Delay in Filing When Using ARINC

Posted by InsuredApple@reddit | flying | View on Reddit | 9 comments

So, I’m at a new 135 and we use ARINC for filing. I’m used to ForeFlight to file all flight plans, and when I “file” a flight plan, it gets sent off and I receive a confirmation email right away, and ATC updates to my filed route come through pretty quickly as well.

Now with ARINC, it seems to file “something” because I can see the flight in FlightAware, but there is no route.

I was told that ARINC will file the flight plan 2 hours before the flight.

Is that… is there any way I can push a flight plan out sooner, so I can prepare for a next-morning flight fully the night before?

Why can't you prepare the night before ? Whem I file with arinc I just know that 2 hrs prior I'll get the email. It doesn't prevent me from doing any necessary planning just because it hasn't pushed out yet.

Hm, well then any ATC changes will come through when I’m driving to the airplane. It’s not the apocalypse, but it would be nice to get the “final” route all loaded in ForeFlight and stuff… :) I’ve got a flow.

A lot of times those route changes are because of the airspace situation 2 hours before departure. We can't tell you what amendments might happen the day before because we don't know what will be happening tomorrow. The closer to departure the better we can make strategic edits. That's why sometimes you'll get a new route just as you're about to take the runway or already enroute.

Gotcha. So ERAM applies some “logic” to the submitted flight plans, then it gets sent to different facilities and is queued up for review closer to the departure time?

I'm not a pilot and I've never used ForeFlight, but here's what I think is happening based on comments from pilots on Reddit.

There are two broad categories of amendments: Adapted [Departure, Arrival, Departure-Arrival] Routes, and manual changes.

ADRs/AARs/ADARs are automatically applied by ERAM based on certain parameters, namely: your departure airport, your destination airport, and your requested altitude. They can also depend on the airspace flow in use at the time. Only the very first controller to see your printed flight progress strip will even know that you filed anything different; everyone else down the line will see the adapted route only, with no indication that your route was even changed.

A manual change is just that, a manual change.

What I think happens is that ForeFlight (maybe ARINC too) can advise you if you're going to get an ADR/AAR/ADAR. Perhaps ERAM sends a message back to ForeFlight, or perhaps ForeFlight has just asked the FAA "please can we see the config file so we can add that logic into our software too." But ERAM does not report back when a controller makes a manual change to your route.

I'm not sure what's going on with timing differences between ForeFlight and ARINC though.
