All figures referencing 4 decade-old, sturdy, yet uncalibrated limbs
Aileron:
Breakout 5-6 pounds at the horn. 25 degree bank ~8-10 pounds.
Elevator:
Breakout at least 10 pounds. 5 degree nose up 20-25 initial then 15 pounds untrimmed.
Rudder:
25 pounds or more breakout. around 35 pounds for 15-20kt crosswind landing correction. V2 engine out before trim over 75 pounds in the sim (CAE)
Aircraft speed vs control column forces:
In comparing cruise vs approach speed control forces, we need to remember the deflection angles will differ by a factor of 2-4x or more for the same command request. Add in the by-statute (FAR/JAR) force gradient requirements and we are entering complex ratio territory, however, generally inputs at slow speeds require more force for the same maneuver.
