11.13 Steering Flashcards
How are light aircraft steered
By direct mechanical steering linkages connected to the rudder pedals
How is steering normally controlled on large aircarft
Via a small wheel or tiller located in the flight deck
What keeps system under pressure at all times
Accumulator and relief valve
How is NWS often controlled
Mechanically via cables
How is NWS often actuated
Hydraulically
What stops the nose gear turning past the desired point
Follow up linkage
What is a second advantage if having NWS
Acts as a shimmy dampener
What is shimmy dampening
Dampening vibration or shimmy of movement
When do aircaft NWS self centre
When there is no weight on wheels
What causes NWS to self centre
A cam inside the strut which lines wheels up to be straight when there is no weight on them
What are 3 advantages of main gear steering
Reduces tyre scrub, reduce aircraft turn radius and decrease force necessary to turn aircraft
When should be done to NWS when towing
Safety towing pin should be inserted to keep system neutral
