Floppy Link,
What do these airplanes do if the pilots don't do anything after the cleared route is programmed in? Does it fly any clearance limit and hold? If you are cleared to the destination airport will it just shoot an approach or hold at the IAF, or something else altogether? If it's an N-reg I guess it needs the instruction manual to be on board, I suppose you could always get it out and look PTT button up in the index
