True enough for stick-controlled aircraft, but "modern" ones with control wheels are usually flown with the left hand (leaving the right one free for power controls/navigation/communications/etc.). Unless, of course, the pilot is an instructor and flying from the right seat (and that's probably the rear seat for planes with sticks). -- GregR > Pilots of fixed wing aircraft have traditionally held the stick with > the right hand using the left hand for handling the power controls. > > The throttle for most helicopters is a twist grip (like a mororcycle) > mounted on the colective (which is moved up and down) and so is the > power control used by a helicopter pilot with hi left hand, same as > fixed wing.
