Which of these statements about rudder pedal nose wheel steering is correct?
  • A
    Rudder pedal nose wheel steering does not function during take-off.
  • B
    Rudder pedal nose wheel steering functions on the ground only.
  • C
    Rudder pedal nose wheel steering provides a larger deflection of the nose wheel as hand wheel steering (tiller).
  • D
    Rudder pedal nose wheel steering provides the same deflection of the nose wheel as hand wheel steering (tiller) control.

Nose wheel steering on commercial aircraft is hydraulically powered and is only possible when the aircraft on the ground by the use of squat switches. The hand wheel steering (tiller) has a large deflection, up to 78 degrees, and the rudder pedals can also be used for nose wheel steering but only to a maximum of 7 degrees.
