Comet 2C Elevator Trimming
The Comet 2C as used by the RAF had a large elevator trim wheel handily beside the centre power lever quadrant. The break-out force for elevator using the spring feel powered flying controls was measured at 5 pounds. There was a tiny amount of friction on the trim wheel. Consequently I found that nearly all manoeuvres in pitch could be best achieved by resting the left hand on the yoke and making all pitch inputs with the right hand using the trim wheel.
It was a bitch of a thing to fly otherwise having breakout forces for ailerons of 11 pnds and 35 pnds for rudder. Spring feel gave absolutely no feel of indicated airspeed.
We TPs at Boscombe Down recommended a change from spring feel to Q feel.
