6 seater rental for Catalina island?

The context is carrying passengers during paid Part 91 flight. For passenger-less training the student is consider part of the crew. So no, the lunch-stop example during a standard cross country training flight doesn’t apply here. For Part 91 with passengers you are able to stop for human or aircraft needs. So yes you can be cute and say that while flying over the ocean during this HP endorsement training flight with 3 pax we decided to use the bathroom at this popular tourist destination for several hours. For your specific case, what would really suck is to have the school agree over the phone, travel to the airfield, and then go through paperwork only to have the randomly assigned CFI decline to do the flight when they see that this is really a charter flight with some training sprinkled on top. Now you’ve burned 3 hours of trip. Also, you’ve already said that the CFI would be acting PIC, so why put him in that position? Google “FAA Dual Use Memorandum”. There are a dozen or so memorandums that touch on this very topic of pax and paid Part 91 operations. I fly for engineering firms and this situation becomes tricky with how we can onboard and offload 3rd party operators during tests without triggering a dual-use flight. Most involve the gov so sure, we have more oversight than Joe Blow’s flight school.
