Control

Pilot force daN

Method of force application assuming single lever control systems

Elevator

35

Push and pull handgrip of control stick

Ailerons

20

Move handgrip of control stick sideways

Rudder

90

Apply forward pressure on one rudder pedal

Airbrakes

Spoilers

Wing-flaps

35

Push and pull handgrip of control lever

Towing cable release
