I don't understand the C* lingo, nor do I fly an Airbus or any of these new-fangled FBW machines, but doesn't the Airbus just automatically trim the speed out ie it's pitch stable (slow down, no backtrim required), instead of Boeings being speed stable (slow down, back trim required)?
In any case, with other underslung aeroplanes eg 777, doesn't the FBW remove any thrust-pitch coupling using I imagine first the elevators then trim with the pilot even knowing it's happening?
I'm with ACMS. Control a "normal" aeroplane with the elevators, then trim away any residual force. You can use Vesspot's technique of anticipating trim requirements (flaps extension say) but you run the real risk of subconsciously doing it more and more. This is bad.
Pulling and pushing in the sim I say to myself occasionally "Bloggs, the speed and config hasn't changed, stop trimming!!".
