Landing Gear, Brakes, Nose Wheel Steering Flashcards
How is the main landing gear held in the up and down position
Mechanical up and down locks
How is the nose gear held in the up and down position
Over center mechanism
Do the forward nose gear doors remain open after a normal extension
Yes
How are the nose gear doors actuated
Mechanically
Note: The nose gear doors will remain open whenver the nose gear is extended.
What is the purpose of the brushes on the main wheel wells
They create an aerodynamic seal for the main landing gear bay
Where do you look to determine the position of the landing gear
EICAS primary page
