This is just some cool-golly-gee-whiz stuff.
I was playing around with the cruise control with auto throttle armed last night. If the throttle was up to maintain a speed and you bring the engine back to idle, then resume cruise, it will command the throttle to maintain speed. (I thought auto throttle was strictly tied into the eHydro pedal position) Does not work with Auto Throttle disarmed.
Just some stuff to impress your friends and neighbors with,.....
