API Documentation: Sidestick

Sidesticks

The sidesticks are the pilots' primary control for manual flight.

They are springloaded and automatically return to the neutral position. They do not receive any feedback from the control surfaces as Airbus use the fly-by-wire system without force feedback.

When the autopilot is engaged the sidsticks are locked in neutral position.

If the pilot applies a force above a given threshold:

  • The sidesticks unlock
  • The autopilot disengages
  • The AUTO FLT AP OFF alert triggers

Each sidestick has two controls:

  • The Radio Push To Talk switch
  • The sidestick pb, for autopilot disengagement, or sidestick priority

At all times, only one flight crewmember should fly the aircraft. However, if both flight crewmembers use their sidesticks simultaneously, their orders are algebraically added. The flight control laws limit the combined order to the equivalent of the full deflection of one sidestick. In this case, the two green SIDE STICK PRIORITY lights on the glareshield come on and "DUAL INPUT" voice message is activated.

A flight crewmember can deactivate the other sidestick and take full control, by pressing and keeping pressed the sidestick pb. To deactivate the other sidestick, the flight crewmember must press their sidestick pb for 40s. The other sidestick is permanently deactivated, until any flight crewmember presses their sidestick pb. If both flight crew members press their sidestick pb, the last pilot to press gets the priority. If one sidestick was deactivated on ground, the CONFIG L(R) SIDESTICK FAULT alert is triggered at takeoff power application, or during the TO CONFIG test.

Sidestick priotity is currently not available or INOP in the FBW A32NX for Microsoft Flight Simulator.

Steering Handwheels (Tiller)

The steering handwheels, also called tillers, which are interconnected, can steer the nose wheel up to 75 ° in either direction.

After takeoff the steering system centers the nose wheel automatically.

The center button on either handwheel removes control of nose wheel steering from the rudder pedals until the button is released.
