Landing Gear system description

Question 1

How is the landing gear operated

Answer 1

Hydraulically actuated via a reversible electrical pump.

Question 2

How is the gear maintained in the retracted and extended position respectively?

Answer 2

Hydraulic pressure keeps the gear retracted. Should a leak develop springs, and aerodynamic loads will cause it to drop and downlock hooks pressurized by springs lock the gear into place.

Question 3

In case of an emergency extension, why should the gear selector be placed in the down position before pulling the emergency gear extension knob?

Answer 3

Placing the gear selector in the down position prevents the pump from trying to raise the gear.

Question 4

Describe the nose gear steering

Answer 4

Steering arc is 42 degrees, upon retraction the steering linkage is disconnected to reduce rudder pedal loads. Shimmy tendencies are reduced by a gear centering spring

Question 5

Where is the hydraulic reservoir located?

Answer 5

Behind a panel in the nose baggage compartment
