12.54.4. Explain typical steering and braking systems.

12.54.2. Describe the two common types of undercarriage system (tricycle/tail wheel).

Tricycle
– steering is nosewheel steering controlled by rudder pedals
– braking is from main wheel brakes / disk brakes fitted to each main wheel and operated independently through the upper portion of the rudder pedal
– visibilty is good
– taxiing speeds must be kept under control, but control is easy to achieve
– watch when crossing line depressions as the propeller tips are close to the ground – and cross at an oblique angle

Tail Wheel
– older tailwheel aircraft may not be fitted with brakes
– taxiing controlled by rudder and slipstream (engine)
– forward visibility is usually restricted
– weaving when taxiing enables pilot to see ahead
– unstable on the ground
– directional control may be lost if a large swing occurs (ground loop)
–
– steering
– braking
