B777 Speed Trim
Can any one who flies the 777 enlighten me as to how the speed trim works?
I fly the airbus and many years ago the 737, so it's a new concept to me.
The way I have read it is that in the Airbus if you only increase thrust you will fly straight and level but will speed up. The aircraft will compensate trim automatically for speed changes.
In the Boeing if you only increase thrust, the aircraft will pitch up to maintain the speed it was trimmed at.
So the Airbus is flying straight and level but faster, and the Boeing is now climbing but at the same speed.
I'm assuming speed trim is used for the Boeing because the flight control system uses the stab as well as the elevator to give the pilot what he wants when he makes a pitch control input, but I can't get my head around how it works.
Is it as simple as set pitch and power and then trim out the force?
Thanks in advance
