Very interesting, thanks for the informative replies, I'm surprised that autothrottles have been around for some time in fighters but I can see how it makes sense.
Couple more questions, any of these autopilots have a vertical speed / ias hold mode for use in climb or descent and lastly does your on board nav data base contain named civilian waypoints or even airways that you could proceed direct to or navigate on ?
I would doubt you would have a civilian data base like that as It would use up so much memory that you want for the military mission,I suppose you don't fly routes or to waypoints like us civilian types but just curious.
