11.13 Landing Gear Flashcards
What are the advantages of a nose tricycle gear system over a tail system
Less lift, able to brake harder, more vision
What part of the undercarriage supports the aircraft weight
Shock strut
What characteristics will a shock strut display if over serviced with oil
Very harsh
What two internal components of a shock absorber provide damping during extension
Laminar flow orifice and tapered metering pin
What component will transfer vertical load to the airframe with out imparting torque
A spherical bearing
When will the auto brake system disengage
When the pilot uses the brakes
What is the principle operation of a wheel speed transducer
Converts speed of the wheel to an electrical signal
What component will close if the brake line pressure differential gets too high
Hydraulic fuse
What effect will thrust reverse have on the auto brake system
The auto brake will reduce pressure to keep preselected deceleration rate
What is the purpose of the torsion link in the MLG
Prevents inner and outer cylinders turning
How does the shock strut act on landing
Compresses quickly and extends slowly
What is the purpose of the truck position actuator
Moves gear back and allows for retraction
What is tyre size 8 for
Very heavy or freighter aircraft
What is the purpose of the red dot on the fire
