A320 Sidestick resistance
Anyway here know the amount of force required to maintain an Airbus sidestick at full displacement, both fore and aft? Specifically 320, but I'd bet Granny they are all the same figures. Also, but secondary, would be the amount of degrees displacement from the vertical at max. displacement all-axis. Questions are from a physiotherapist for rehabilitation purposes.
Thanks,

(Putting anorak well and truly on)
The figures copied from an Airbus publication and converted from horrid Euro units to pounds are:
Breakout force: 1.1 pounds
Pitch: Fore and aft. +/- 16 degrees 22.5 pounds
Roll: Outboard 20 degrees 5.6 pounds.
Roll: Inboard 20 degrees 7.8 pounds.
Note that the force is different for inboard and outboard roll. Airbus found during development that your arm is stronger moving inboard than outboard and fine tuned the forces to make left and right roll feel the same. Try moving the stick left and right holding it from above next time you are at work, you can clearly feel the force difference.
(Anorak off and safely stowed till next time)
