Stump the chump! 2 weeks until my checkride. KVNY
Posted by franziskanerdunkel@reddit | flying | View on Reddit | 224 comments
I have my checkride in 2 weeks at KVNY, curious if anyone knows what practice area the DPE might use and what airport we would do landings at since VNY runways are closed to pattern work (whiteman?). From my research the examiner seems to like airworthiness and airspace questions.
Greedy_Requirement_4@reddit
Based on population, it'll be specifically stated in the CHUG
Greedy_Requirement_4@reddit
Why is Los Angeles depicted in a different font than Santa Clarita?
franziskanerdunkel@reddit (OP)
Bigger
randombrain@reddit
Why do Class E cloud clearance requirements change when you reach 10,000' MSL?
Why are Class B cloud clearance requirements "clear of clouds" instead of the more common "some set distance away from clouds?"
Same for SVFR, what makes it safe to operate right up to the edge of a cloud?
Hint: all of these questions are related.
Separate question: where is it possible to be granted an SVFR clearance?
franziskanerdunkel@reddit (OP)
Above 10,000 there are alot more jets and fast moving aircraft where the closure rate between us will be much faster. I don't want to be close to a cloud that could have a jet ripping though it.
Class B provides radar separation from other aircraft
For SVFR, I would assume there is separation provided from ifr aircraft aswell.
I can get a svfr clearance at a class D during the day
randombrain@reddit
Good on the first three! For the last question, it's not complete enough and it's missing some locations. There are more places you can get an SVFR clearance and I also want to know what's the highest altitude at which an SVFR clearance can be valid.
franziskanerdunkel@reddit (OP)
Okay I would say charlie and bravo can offer it as well, as long as the allow svfr. I highest altitude in terms of the airport or how high I can go?
randombrain@reddit
Maybe you should check the regulation on SVFR. "Charlie and Bravo" is both too broad and not fully complete.
franziskanerdunkel@reddit (OP)
Yes looks like I need to. I would probably have it in my personal minimums to not use SVFR. I don't want to be that close to weather as a new ppl
beastboy4246@reddit
Let's go a bit further. Look at your sectional.
Can you get SVFR at LAX? What about SMO?
Let's say you get SVFR at SMO for the day. What weather requirements are needed?
What about night about SMO? Can you get it at night? What's different about Night SVFR vs Day SVFR?
franziskanerdunkel@reddit (OP)
No svfr at lax. Yes at smo.
Needs to be less that 3 miles viz. Then i can leave if they approve svfr and I stay one mile viz clear of clouds. Needs to get to vfr conditions when I leave the airspace.
No svfr at night unless you have a ifr rating.
beastboy4246@reddit
Good so what makes you say no at LAX but not for SMO?
Also visibility is 1 SM not 3 SM
franziskanerdunkel@reddit (OP)
Lax says no svfr above it on sectional
Viz needs to be worse than 3sm in order to ask for svfr.
beastboy4246@reddit
Good. So what that means is you can't get SVFR everywhere only at airports where it is allowed. Where you would find that list is in Part 91 Appendix D Section 3. So it's allowed not everywhere for that reason.
Ah yes I misread your answer before. So yes to ask it needs to be less than VFR mins and with visibility greater than 1 SM. Nicely done!
randombrain@reddit
Not true actually.
Yes, but the book tells us that we can issue an SVFR clearance in worse visibility if an emergency exists. Which is a little bit redundant in that we can always deviate from an rule if necessary to assist with an emergency (2–1–1d3), but I guess they really wanted to drive that one home.
franziskanerdunkel@reddit (OP)
Thank you
beastboy4246@reddit
No problem good luck on your checkride you seem more than ready for it!
franziskanerdunkel@reddit (OP)
I hope so. I just dotn want there to be some stupid thing I fail on
randombrain@reddit
Not correct, although a lot of controllers don't realize this too. 7110.65 7–5–1b.
And you still haven't answered the altitude question. Your anwer should be a direct quote this from the regulation, because it's right there at the front of the section...
Jwylde2@reddit
Can you fly over LAX without talking to ATC?
franziskanerdunkel@reddit (OP)
Yea I can go through the la special flight rules corridor
Jwylde2@reddit
You want to go on a solo flight. You’re one year into your most recent BFR, your medical is current, but you haven’t flown in six months. Are you legal to fly?
franziskanerdunkel@reddit (OP)
I'm legal but not profiecent. I have personal minimums in place that I wpuld want to fly with an experienced pilot or cfi first
Jwylde2@reddit
Now let’s say that under these circumstances, your friend wants you to take him flying. Are you legal to take him?
franziskanerdunkel@reddit (OP)
Nope I need passenger currency 3 to and lngs in the proceeding 90 days
Jwylde2@reddit
Okay.
If you do these takeoffs and landings at night, can you do the landings as touch and goes? And, by doing them at night, would you be able to take him on a day flight?
franziskanerdunkel@reddit (OP)
Well they could but they wouldent count for currency. If i want to be current to carry passengers at night i would need 3 takeoffs and 3 landings to a full stop one hour after sunset to one hour before sunrise in the last 90 days. Yes night currency counts for day also
PencilsAndAirplanes@reddit
You’ll likely use the Simi Valley practice area if your XC is taking you that way. I’d be prepared to do pattern work at KCMA, but it wouldn’t hurt to practice getting in and out of WHP just in case. This all assumes that you actually fly, of course—worst case scenario is that you’ll reschedule or be discontinued and have to finish up with someone else. I’d say odds are about 50/50 on that. Good luck.
franziskanerdunkel@reddit (OP)
Why would we need to reschedule
PencilsAndAirplanes@reddit
Seems like he cancels a lot, or completes an oral and then discontinues and can’t be reached again. It’s a pretty big drag for the candidate.
franziskanerdunkel@reddit (OP)
Did this happen recently
franziskanerdunkel@reddit (OP)
Wonderful 😭
LeoFlightTraining@reddit
What are some tools, outside and inside the cockpit, you can use to help clarify and navigate your busy airspace?
franziskanerdunkel@reddit (OP)
Outside I have airports, freeways, visual points landmarks.
Inside I have atc, gps, vor, ipad sectional.
LeoFlightTraining@reddit
All of your visual checkpoints are pretty compressed on the sectional. What kind of charts could you use to help clean the picture up and see common vfr flight routes?
franziskanerdunkel@reddit (OP)
Could use the tac chart. But I have foreflight so when I zoom in far enough it turns into the tac and it has the visual points listed. Even heli visual points
EHP42@reddit
Don't forget the back of the TAC.
franziskanerdunkel@reddit (OP)

hipsterdad_sf@reddit
Feel free to use this gpt I made to help me train for my IR: https://chatgpt.com/g/g-67c3a8ef004c8191b921871ed071504f-chatcfi - it has as part of the knowledge the ACS, some plates in NorCal, the instrument handbook and some other docs. You can even ask for METARs. For a checkride, you can ask it to behave as a DPE: "I want to try a mock checkride for my PPL. You will play the role of a DPE, in the area of. Ask me questions that would go into the oral portion of the checkride" - or something like that.

God I’d love to fly into LAX one day..
Any_Refuse5318@reddit
Which magneto (L or R) is the impulse coupling on?
How does a magneto work?
What is the wire gauge of the P-lead( and what is its purpose)
Can you conduct an oil change yes or no
If you’re above 10,000 what is your speed restriction and is it True or Indicated?
Calculate cloud base with a 29C temp/ 7 dew point at 769MSL and 20C at 3000 ft msl
Lets say you want to log solo time but you bring your dog aboard, are you still technically solo? Same goes for if you were a pregnant woman (dont make it political)
Lets say you’ve entered an MTR by accident and it has IR298 on the sectional, what direction / alt can you expect hazards from if any?
Lets say you enter restricted airspace and an F16 flys in front of you from right to left, what does this mean?
I got a couple more in the tank but I’ll let you answer these soft ball questions first
franziskanerdunkel@reddit (OP)
Magnetos are a redundant system so if one fails the other should take over. No idea what that is but I would say they both have one. I can look that up.
I answered how a magneto worked in another comment :)
The wire guage of a p lead... if he asks this in going to curl up and die. I would think there isn't a standard guage for the wire in all magnetos so this is some kind of trick question.
I can do an oil change since that's part of preventive maintenance in FAR 43 appendix A
Above 10,000 the speed limit is mach 1. Indicated
11000-769 = 10231 agl. 3500 agl for 20 degrees
Solo time.. i would say yes but maybe there is a regulation for this
Mtr. Well it's above 2500agl and ifr flight. I would expect fast moving military aircraft on that route coming from either direction and within 3 miles of the line.
Interception. I'm going to follow them to the airport they bring me to land at.
Any_Refuse5318@reddit
Pass
But it’s true not indicated
franziskanerdunkel@reddit (OP)
😎
Any_Refuse5318@reddit
I stumped the chump!
franziskanerdunkel@reddit (OP)
Once I get in my blackbird and go mach one I'll make sure to bring my E6B and covert my indicated to true. Wouldent want to break any rules now
Any_Refuse5318@reddit
If u used indicated you’ll have some ‘splainin to do if you live to tell the tale
franziskanerdunkel@reddit (OP)
Haha
Jwylde2@reddit
If you were to depart out of Santa Monica (KSMO), would ADS-B be required? If so, why?
franziskanerdunkel@reddit (OP)
Yes because I'm in the mode c veil of the bravo
Jwylde2@reddit
Are you sure? What regulation states this?
franziskanerdunkel@reddit (OP)
91.215
Jwylde2@reddit
I’m thinking more along the lines of 91.225(d)? 🤔
franziskanerdunkel@reddit (OP)
Ah looks like if it never had an electrical system it wouldent need it. So maybe a cub or something or a glider
Jwylde2@reddit
That’s 91.225(e), and yea if it never had one you wouldn’t need it.
So you were correct in stating that the Mode C & ADS-B Veil requires it. But the examiner may use an example where you’re under, say, you’re departing a satellite airport under a Charlie shelf, where you won’t have the veil. 91.225 is your ADS-B FAR.
franziskanerdunkel@reddit (OP)
Under a bravo and charlie shelf i need mode c and adsb
TheOnlyMuteMain@reddit
You’re going to go fly some friends during the day in a 1966 Piper Cherokee 180 but your anti collision lights aren’t working. Can you legally still fly?
franziskanerdunkel@reddit (OP)
Yes I belive 1966 is before the year they where required. But I'll need to make sure I still have mode c and adsb out if I'm in this airspace.
TheOnlyMuteMain@reddit
Correct, March 11th 1996 is the date. My DPE specifically asked me for that, but I doubt going into that much detail is required on most checkrides. Good luck!
franziskanerdunkel@reddit (OP)
Thank you
3greenandnored@reddit
Though this was nearly 30 yrs ago, Mark used the west practice area over Simi Valley for my students. He'd also have you divert to either CMA or Santa Paula. Again, this was almost 30 years ago. Just know that He will get more agitated as the check ride goes on, this is not your fault!!! It's his nicotine addiction! Also He'd conduct his check ride from his office at Schaffer Air Ambulance Service at the SW corner of the field.
Mark was a fair DPE, but didn't like BS. If you don't know something, you don't know...but if you know where to find it you'll be fine.
Good luck!
franziskanerdunkel@reddit (OP)
Thanks for that info. I keep hearing about this smoking thing and him yelling at people trying to get finished as soon as possible. Sounds like uneeded stress on an already stressful day

What is considered populated airspace?
franziskanerdunkel@reddit (OP)
I would say the yellow areas on the vfr sectional are a good place to start. But when there is a large amount of people, buildings, etc
randombrain@reddit
Trick question, the answer is "anywhere you happen to commit a violation is a populated area if the FAA wants to make an example of you." There's an NTSB case where the FAA successfully argued that 20 houses on a 200-acre subdivision was a "congested area."

Greedy_Requirement_4@reddit
Nav logs, know how to get from TC > MC > MH > CH I know a handful of pilot busted their cfi rides cuz of this
franziskanerdunkel@reddit (OP)
TC is the line on the sectional. Then i can get true heading from adding or subtracting wind correction angle. Then magnetic heading from the variation. Then Compas heading from deviation.
chillvilletilt@reddit
What happens if you pull carb heat and cage the attitude indicator at the same time?
franziskanerdunkel@reddit (OP)
Ooo good one. I have very little time in a 6 pack. But since there is unfliltered air coming in with the carb heat on maybe that could effect the vacuum air? But that has its own filter...

ABCapt@reddit
The -27 NE of LAX, what does that mean?
franziskanerdunkel@reddit (OP)
Whats the context of the question?
kbobbert@reddit
There’s a box with “-27” right north of LAX. They’re referencing what that number/symbol references.
franziskanerdunkel@reddit (OP)
Ah got it. It's actually not a - thats just part of a black line outlining the marina. But that's how high the delta airspace of KSMO goes, 2700MSL. If it was a minus though, it would only go up to 2699MSL.
randombrain@reddit
Nope, that's not actually the SMO Delta...
franziskanerdunkel@reddit (OP)
Well the bravo airspace limits will be those fractions, like 40/sfc. I would think the square with the 27 is for smo
randombrain@reddit
It's not though. The square for the SMO Delta is a little bit to the Northeast of SMO Airport on your screenshot.
The square that's in between SMO and LAX is for a different Class D airspace.
franziskanerdunkel@reddit (OP)
Must be hawthorne!
randombrain@reddit
What? Hawthorne is to the Southeast of LAX. You think their Class D exists in either side of the LAX Class B surface area? That doesn't make much sense.
No, that's actually the LAX Class D airspace.
MixGlad6126@reddit
I just found this on my charts the other day. Never been so stumped in my life, glad I know now.

This will be your DPE's fun gotcha, pretty much guaranteed.

PrettyPineapple461@reddit
I am unfamiliar with the local area/practice areas but that appears up north. Are there any NTAs that you’ve visited for pattern stuff?
franziskanerdunkel@reddit (OP)
Whats nta?
Evening_Football_323@reddit
Non-towered airport, I think is what he means my NTA
franziskanerdunkel@reddit (OP)
I've barely done any. Should be on my list probably before the checkride.
Evening_Football_323@reddit
Ooo! Yes you should! It's so fun. If you're flying a xc flight to KDLO as a new private pilot, how would you land there (go into every detail), let's say the winds favor rwy 15.
franziskanerdunkel@reddit (OP)
I would be coming from the south east, so on the acute side of the airport for that right pattern of runway 15. I can come in at traffic pattern altitude of 1300 at a 45 degree angle to that right downwind. 5 miles out i want to report my position and intentions on joining the pattern to land 15. Then calls for base and final and getting off the runway taxing etc. If i was coming from the west, I would do everything the same except for cross mid field at 1800 (500 above TPA) and extend for 2 miles. Then circle back for the same 45 degree entry and decend to tpa.
Evening_Football_323@reddit
Great, im glad you got the right pattern! A few questions. What frequency are you talking on? Do you get weather info? What frequency is that on. What does AWOS-3P mean? What if you are coming in at night, anything additional you need to do? What does 56 mean in the magenta writing after the *L? Anything interesting with the runway markings? (Check the AF/D)
franziskanerdunkel@reddit (OP)
Ctaf is 122.8
Weather on 119.55
Awos is automated weather observation system so its minute weather. 3p is the type of precipitation sensor.
If it's night I want my nav lights on and I have a landing light.
5600 feet runway
I dont have forflight or my chart supplement infront of me can I gave a hint for the airport markings
Evening_Football_323@reddit
Okay, check out the runway on google maps satellite view, pay attention to the rwy numbers. Also, what would you do at night if you wanted the runway lights to turn on? And also are you sureeee that a right pattern for runway 15 is on the east side of the airport?
franziskanerdunkel@reddit (OP)
Oh lol it says 14. That's interesting. I mistook the direction. So 15 is 150 degrees so almost south. So flip those around.. and I can tap the mic 7 times for high, then 5 for medium, 3 for low.
Evening_Football_323@reddit
Fabulous job man! Isnt that odd, good ol magnetic changes. DLO does not have HIRL, only MIRL, so just 5 clicks should suffice. When you make those 5 clicks do you know how long before they will turn off (or change to preset low intesity at DLO)?
franziskanerdunkel@reddit (OP)
Thank you! I want to say 45 minutes is my gut but could be wrong
Evening_Football_323@reddit
So its actually only 15. So let's say you are at KUAO (a local airport to me) after the twr closes. Those lights will completely shut off. So even if the light are still on, its a very good idea to key em up again on final since that should reset the timer (so that they dont cut off while you are trying to land)
franziskanerdunkel@reddit (OP)
Makes sense. Cool thank you! I'm definitely intimidated by the uncontrolled fields i hear there are of alot of unsafe pilots at them.
Evening_Football_323@reddit
Huh, that stinks. I love my un-towered field. Want me to ask any more questions, or are you all good?
franziskanerdunkel@reddit (OP)
Yeah keep going lol! I need the practice. I'm pretty nervous about this checkride especially since vny is having all this construction and shortened runways. And I haven't been confident at all with my short and soft fields
Evening_Football_323@reddit
Okay, sounds great! I have a very important question. Let's say you are on short final, and some dangerous pilot departs in front of you, cutting you off. You initiate a go around, as they start rolling. What is the potential safety conflict there?
franziskanerdunkel@reddit (OP)
I would want to offset so they don't climb into me. Might even make an early crosswind
Evening_Football_323@reddit
Good answer. What aircraft type do you fly?
franziskanerdunkel@reddit (OP)
Pa28
Evening_Football_323@reddit
Tell me your soft field procedure. Takeoff and landing
franziskanerdunkel@reddit (OP)
Soft field takeoff going to do flaps 25. Full back stick pressure minimum breaking no stopping on runway. Going to let the nose lift off ASAP and push into ground effect until Vx of 76 then climb out, slowly retract flaps.
Landing going to come in full flaps and try to keep the nose off. I've tried adding some power in the flare but it's been making me balloon and then smacking down hard. Keep the weight off the nose gear
Evening_Football_323@reddit
Alright, what about short field?
franziskanerdunkel@reddit (OP)
Flaps 25, use all available runway. Full breaks. Full power, check rpm and engine instruments then release breaks. CFI was telling me today to climb clear of obstacle at 60-65 mph but it's not in poh. Plane is old... slowly retract flaps and get to Vy after obstacle
Evening_Football_323@reddit
No Vx published?
franziskanerdunkel@reddit (OP)
From poh
The best rate of climb at gross weight will be obtained at 85 MPH.The best angle of climb gross weight these speeds may be obtained at 74 MPH. At lighter thanare reduced somewhat. For climbing en routea speed of 100 MPH speed and increased is recommended. This will produce better forwardvisibility over the nose during the climb.
Evening_Football_323@reddit
Okay, so yes. The Vx is 74. Do not climb at 60-65, climb at 74MPH, plus possible gust factor, and +10/-5 knots (as specified by acs).
franziskanerdunkel@reddit (OP)
Yeah i guess my cfi took the lower than max gross reduce somewhat to be way lower. I would hope I can ask the examiner what he expects
Evening_Football_323@reddit
No way, don't ask the examiner. You are the pilot, it's your choice. Please go by the book, and not too much lower. Explain to the DPE you will be using the fully loaded number from the book, even if you are not fully loaded, and explain that it is to provide a margin of safety from your stall speed. What is your clean stall speed btw?
franziskanerdunkel@reddit (OP)
Clean is 68
Yes that's been a point of discontent for me aswell. I'll probably go by the book
Evening_Football_323@reddit
Oh my gosh, clean stall speed is 68 and he told you to climb at 60-65? PLEASE DO NOT DO THAT! Anyway, can you tell me about the landing procedure?
franziskanerdunkel@reddit (OP)
Yeah landing configuration stall is 61. For short field i want to pick a point and land on it -0 +200 feet
Evening_Football_323@reddit
Okay, what approach speed should you use?
franziskanerdunkel@reddit (OP)
Around 75 over the fence, 80-85 on approach
Evening_Football_323@reddit
Okay. What flap setting? Also since you have to hit a spot -0/+200 now would be a great time to show off your go around skills. Do not force it. Also please make sure to take any gusting wind into account on your speeds.
photoinebriation@reddit
Alright pick an alternate for MRY and explain why you chose it
franziskanerdunkel@reddit (OP)
Depends on what's wrong at mry, if airport was closed i could pick an airport that had services close by like salinas. If it's for weather I'd turn around and find a different airport with service
photoinebriation@reddit
What’s a common weather phenomena in Monterrey? Salinas is often affected at the same time, though not as severely
franziskanerdunkel@reddit (OP)
Since it's coastal i would say marine layer and advection fog.
photoinebriation@reddit
Yea! So I’d pic an airport far enough inland where if the fog came up then you could divert there
franziskanerdunkel@reddit (OP)
Cool!
Possible_Beginning15@reddit
On your flight plan, be ready to point out any spot along the route where your engine fails for the purpose of figuring out which airport you will divert to, consider winds sloft/glide distance and why (hint: include winds aloft).
On the maneuvers including short/soft field t/o or landing, go arounds... I was expecting each to be a separate maneuver but my DPE mixed them together and once called a go around while coming in to demonstrate another maneuver.
franziskanerdunkel@reddit (OP)
Good advice.
FlamingoCalves@reddit
Approach controller that works this sector….you’re going to go to kcma…. How are you going to navigate there?
franziskanerdunkel@reddit (OP)
Flight following with socal approach. I could follow the 118 freeway through simi valley or go south and follow the shoreline, talking to mugu eventually.
FlamingoCalves@reddit
I’ll be more specific as I’ve unfortunately have had to educate a lot of pilots (even recently had to ask an instructor if there was an instructor on board I could talk to, not realizing. He was the instructor, remember they aren’t all gods )
When will you call for flight following? What frequency? What altitude will you climb to if you can’t get a word in
franziskanerdunkel@reddit (OP)
I'd get it on the ground at van nuys. 120.4. 4500 feet since im going west.
FlamingoCalves@reddit
Get it on the ground, good. If the tower tells you no or they say they’re busy, you tell them approach told you to, and if not ask their name and call the tracon no we will set them straight.
Frequency will be 134.2. 120.4 is also out of service, the transmitter burned down in the fires. It is not am out. That sector north of vny is using 119.85
Also flying to 4500 south of the 118 west bound( if not talking to anyone) is incredibly dangerous. There will be jets all day long descending from 5000 to 4000 to 3000 on their base turns for the ils into Burbank. If you can also monitor guard on a second radio, I use that a lot to reach out for dummies that spend all day trying to kill people
franziskanerdunkel@reddit (OP)
Ahh. Well hopefully I would of got the frequency hand-off from tower. Makes sense, I wonder why they would make that simi valley area a practice area then. We did maneuvers there a week ago. Approach was super busy we couldent get a word in just like you were saying.
FlamingoCalves@reddit
That’s exactly why I tell everyone to get it on the ground while you’re taxiing or twiddling your thumbs. Doing it in the air only ads to the complexity
As for why? Why does whiteman airport exist with the departure path right through thre van nuys final? With not even Charlie airspace. If you only knew how many near mid airs I’ve seen, you couldn’t pay me to fly in our out of whiteman.
franziskanerdunkel@reddit (OP)
Yeah i always have flight following. I'm not a fan of Whiteman either it's a narrower runway than I'm used to and has those smoke stacks on the upwind...
Key_Research7096@reddit
In the airport data for LAX, on the bottom line there is "L", what does this mean? HHR has "*L", what's the difference?" How high does VNY's airspace extend? How long is L70's Runway? Which runway is right traffic? Partway through a steep turn you notice you're holding the yoke in the opposite direction, why is that? Why is more right rudder needed in a steep turn (or any turn) to the right? What are your daytime VFR fuel requirements? How about night? You're landing behind a larger airplane. What would you do to avoid entering their wake? You want to know about some of the limitations of your airplane, where do you find them? How would you prove your airplane is airworthy?
franziskanerdunkel@reddit (OP)
L means there is airport lighting *L means lighting has limitations Van nuys airspace is delta to 2999' msl L70 4200 feet. Rp 22 Steep turn... maybe not enough rudder or back pressure Left turning tendencies Day fuel requirements is enough fuel to destination plus 30 minutes at cruise setting. Night is 45 mins. Landing behind a large plane I'd stay above their path and land further down the runway than they did Limitations in section 2 of the POH, i can look at the TCDS aswell Airworthiness can be proven by passing inspections and ADs, a thorough pre flight, checking for inoperative equipment

How does density altitude affect the distance of your takeoff roll? Is your IAS faster or slower at higher density altitude? How about your ground speed?(I was asked this on my ppl)
franziskanerdunkel@reddit (OP)
The higher the density altitude the less dense the air will be around my plane. Less air under the wings means less lift, less air pushed by the propeller means less thrust. Going to make my takeoff roll longer. IAS not effected by density alt. Ground speed is effected by wind
Penguin_Named_Piplup@reddit
You got 2/3 of it right. IAS won't be affected, as that remains constant despite the Density altitude. Takeoff roll will be longer as well. In flight, ground speed is affected by wind but on the ground while you're on your takeoff roll, it will be affected. Since the air is less dense, there is less air being "pushed" under your wing. So in order to get the same volume of air under your wing, your aircraft needs to go faster on the ground to get the air under your wing. So essentially, your ground speed will be faster when taking off at a higher altitude airport than at sea level, aka at a higher density altitude vs a lower one
franziskanerdunkel@reddit (OP)
Wouldent that be indicated airspeed? I don't understand
Penguin_Named_Piplup@reddit
Your indicated airspeed is derived from the ram air hitting the dynamic port. When you're at higher altitudes, the air pressure is less as well as the air density. So in order for you to get the same amount of air pressure hitting your dynamic port, you need to increase the pressure. You do this by increasing your ground speed which increases the number of air molecules hitting dynamic port. If your aircraft is physically moving faster, you are having more air molecules hit the pitot system. Hence, your IAS will still show your normal takeoff speed, as the number of molecules hitting your dynamic port will be the same as at sea level, but your aircraft will physically be moving faster to do so, ie your ground speed. I may not be explaining it the best so let me know if that made sense.
If it makes you feel better, I kinda missed this question on my oral as well but the dpe I had was great and helped me get to the answer by asking me other questions to help me understand this
franziskanerdunkel@reddit (OP)
I would say that your true air speed would change not ground speed, isn't ground speed just strictly your speed over the ground?
Penguin_Named_Piplup@reddit
I guess to a degree yes. Your ground speed and TAS are technically the same in this case since you're not actively flying yet. When you're taking off there is no wind velocity so your ground speed and TAS are the same. So I guess in that sense, you're correct and understand the concept.
franziskanerdunkel@reddit (OP)
Kewl
Red-Truck-Steam@reddit
Hey I have my ppl and never even thought of that. That makes perfect sense!
e3027@reddit
Your indicated airspeed will be the same at a higher density altitude but your ground speed will be higher.
franziskanerdunkel@reddit (OP)
Ground speed as in speed over the ground right?
e3027@reddit
Yes, assuming the wind is the same. Its really your TAS that will be higher.
franziskanerdunkel@reddit (OP)
Ahh that makes more sense
Penguin_Named_Piplup@reddit
Say you're flying on a cross country flight and your current route happens to take you to a rural area, about 50 miles to your closest airport. You suddenly suffer a complete electric failure. How long do you have to diagnose your problem and/or land before your engine fails?
franziskanerdunkel@reddit (OP)
I would be about 30 mins to an airport depending on the wind. I have as much time as the fuel on board will take me since the engine is independent from the electrical system. Would expect light gun signals if its a towered airport
Penguin_Named_Piplup@reddit
Perfect! I was asked this on my commercial oral buuutt this exact scenario happened on my first cross country flight after I got my ppl! I was 5 miles away from an airport in my case but I wanted to make sure you remembered they're independent systems. Making sure you're a safe pilot. Dude you got this! You're answering everything well. Don't forget to get a good night sleep the night before. You got this, good luck!
franziskanerdunkel@reddit (OP)
I bet you where still sweating lol! Thank you
Penguin_Named_Piplup@reddit
I definitely was. The hardest part about this was remembering my light signals! xD
franziskanerdunkel@reddit (OP)
I have a general understanding but I have a cheat sheet on my knee board
I-r0ck@reddit
Explain how the vacuum system works on your aircraft. What would happen if the vacuum is too high, and what about too low? What is ADAHRS and what would a failure of it look like?
franziskanerdunkel@reddit (OP)
There is no vacuum system in my aircraft it was removed. But if I did have one it would take vacuum pressure from a pump mounted on the engine and suck air through my gyroscopic instruments. If it's to high or low, the regulator broke. Air data and attitude reference system uses air data computer, magnetomiter, and accelerometer to replace the gyroscopic instruments
I-r0ck@reddit
And what would happen if ADARHS 1 were to fail?
franziskanerdunkel@reddit (OP)
Well I have 2 G5s so I would think I would get some erroneous info on my mfd. I would stop using that one and switch my second g5 to mfd
I-r0ck@reddit
On the G5 it would automatically detect the failure and X out all the inoperative equipment, it will also automatically switch the second G5 to PFD mode. Do you know how this failure would affect other systems in your aircraft?
franziskanerdunkel@reddit (OP)
I would think that it would be isolated to the one g5.
I-r0ck@reddit
It would depend on how your aircraft is configured but you might also expect your GPS to loose some functionality, your transponder might loose its mode C and ADS-B capabilities, and your autopilot might not function.
franziskanerdunkel@reddit (OP)
Well I also have a gns430, I would say the GPS data is from that.
I-r0ck@reddit
Some GPS’s use the altimeter for its altitude information. If your G5 fails you might expect a warning message on the GPS informing your that it lost that information(this won’t matter for you yet but for IFR it’s important)
franziskanerdunkel@reddit (OP)
Ah okay that makes sense. Also the altitude reporting for the transponder right? Although i would think it uses my GPS altitude
I-r0ck@reddit
It would depend on how your specific aircraft is configured. It might be GPS, it might have its own encoder, or it might get the data from the G5.
franziskanerdunkel@reddit (OP)
Cool! Do you think this is more of an ifr question? Or is it fair game on ppl checkride
I-r0ck@reddit
He’s unlikely to get this deep into it, but I do think it’s important to know how a failure of one system effects another and he might ask about it.
franziskanerdunkel@reddit (OP)
Yeah not much of the training talks about the new electronic equipment that replaced the old vacuum stuff
Traditional_Half_788@reddit
As a private pilot, if your friend wanted to go up with you while you just practiced flying the pattern, how would you split the cost?
franziskanerdunkel@reddit (OP)
Well I need to pay atleast the pro rata share of the flight expenses. I'd need to make sure doing pattern work was my idea since we need a common purpose for the flight
Traditional_Half_788@reddit
This tripped me in mine, I thought like you.
According to my DPE, in reference to AC 61-142 (when they start pulling ACs I feel like they are just digging for a stump), we could not do pro rata as there would be no common purpose. It being your idea wouldn't matter as there is no real reason your friend being up there would qualify because he is just along for ride and you're not going to a different location. At least that's how it was explained to me, the AC does go into more detail.
franziskanerdunkel@reddit (OP)
Seems pretty ridiculous lol. Did you fail for that?
Traditional_Half_788@reddit
Lol, no.
You shouldn't fail an oral on non-safety related questions. Check ride orals are more or less a DPE gauging you're overall knowledge, hit a predetermined level in THEIR head (the ACS doesn't have a percentage, remember?) and you pass.
franziskanerdunkel@reddit (OP)
Ah. Yeah so would that make going for a little sight seeing flight and heading back to the same airport you started at would be illegal lol
Significant_Yam3012@reddit
What is the speed limit of a Bravo airspace?
franziskanerdunkel@reddit (OP)
250kts
Significant_Yam3012@reddit
This is a common misconception, the reg you're referring to is 91.117 (a). but it never states a speed for a class B airspace
franziskanerdunkel@reddit (OP)
What would the answer be then? No speed limit?
Significant_Yam3012@reddit
Since bravos start TYPICALLY SFC-10000MSL you still abide by that reg, however the Denver bravo goes up to 12500msl so in that 2500’ there is no speed limit while in the bravo
franziskanerdunkel@reddit (OP)
Ahhh tricky
Significant_Yam3012@reddit
Except up to but not including Mach 1
Kai-ni@reddit
Gee I wonder why the examiner likes airspace questions e-e
franziskanerdunkel@reddit (OP)

What do magnetos do?
How does your pitot static system work?
What type of atmosphere is generally associated with thunderstorms?
How do you get forecasted weather at your destination?
franziskanerdunkel@reddit (OP)
Magnetos use an electromagnet to send electricity to the spark plugs to ignite the fuel air mixture in the cylinders. They run off the rotational force of the engine so they don't need outside electricity to work.
Pitot tube hole is poiting forward and gathers ram air. Static port is in a place where air is calm. These can be compared to gather airspeed information. Static port air can also be sent to altimeter and vertical speed indicator where the air goes into an aneroid wafer (in my case an air data computer).
Unstable atmosphere, moisture, lifting force
I can call 1800wxbrief for a weather briefing, look at TAFs, prog chart
Effective-Scratch673@reddit
Why do we do the magneto check?
franziskanerdunkel@reddit (OP)
We want to make sure both magnetos are working since i want that redundancy if one fails. Make sure there is no fouled spark plugs, normal rpm drops
Effective-Scratch673@reddit
Good, but you're missing something else that is really important...
franziskanerdunkel@reddit (OP)
Ungrounded p lead could be a problem, no rpm drop
Effective-Scratch673@reddit
Great! And by ungrounded you mean what? What is that potential problem ?
franziskanerdunkel@reddit (OP)
Well when you ground a magneto, like when you turn it off, the electricity made by the magneto takes the path of least resistance into "ground" which is the aluminum frame of the aircraft where the electricity can disappate. If ungrounded the electricity would make it to the spark plugs and could ignite the fuel in the cylinder. So if the p lead broke and the magneto was not grounded, if someone came and spun the propeller the magnetos could click off and start the engine
Effective-Scratch673@reddit
Niceee! I'm not being anal just because, but expect this kind of stuff on your Checkride... DPE is not out trying to get you, most of the time they just want to know how deep your knowledge goes, so don't get nervous if this happens. Keep your answers simple as you were doing with me, unless asked to elaborate. If you don't know something, say so, and explain where you would be able to find the answer. You seem well prepared ! Good luck !
franziskanerdunkel@reddit (OP)
Got it. Thank you
SpacisDotCom@reddit
How do we stump you?
Traditional_Half_788@reddit
Give him questions that would be asked to a PPL student during a check ride... unless you're being facetious.
SpacisDotCom@reddit
Like what?
rFlyingTower@reddit
This is a copy of the original post body for posterity:
I have my checkride in 2 weeks at KVNY, curious if anyone knows what practice area the DPE might use and what airport we would do landings at since VNY runways are closed to pattern work (whiteman?). From my research the examiner seems to like airworthiness and airspace questions.
