Landing Gear Flashcards
Which hydraulic systems must be powered when checking the brake wear indicators?
System 2 and 3, with the parking brake set.
Which hydraulic system powers the landing gear?
System 3.
Which hydraulic systems can be used to assist manual landing gear extension if the main system fails?
System 2.
What effect will the loss of both the #2 and #3 hydraulic system have on the landing gear?
You will not be able to lower the nosegear—no pressure available to force it off the uplock.
In the event of a #2 and #3 hydraulic system failure, what emergency braking is available?
Brake accumulators in both systems should provide reserve pressure for six applications with the anti skid OFF.
How is the Anti-Skid test performed?
The Anti-Skid Control Unit is equipped with a self test feature. It is also tested during the originating check by cycling the Anti-Skid switch.
What should you do if you are unable to raise the gear handle after takeoff?
Use the DN LCK REL button next to the gear handle to release the downlock mechanism
What effect will the loss of either the #2 or #3 hydraulic system have on braking capability?
Anti-skid braking will be available from the remaining system, with a 50% loss of stopping capability.
Locked wheel protection is provided by the anti-skid system upon landing. When will the system allow braking to occur?
Wheel spin up speed reaches 35 kts or 5 seconds after WOW signal is present.
When the parking brake is set and hydraulic systems are deactivated, what effect does it have?
Pressure will bleed off in the #2 system but will be maintained from the #3 system brake accumulators because of a parking brake shutoff valve.
After an overheated brake is cooled in flight by lowering the gear, how can the pilot reset the BTMS indicating system?
Press the BTMS OVHT WARN RESET button on the landing gear panel.
With the same indications of an overheated brake on the ground, what should you do?
Do not reset the BTMS system until maintenance has had a chance to inspect the brake.
The nosewheel steering system allows travel of _______ from neutral with the rudder pedals and ______ with the handwheel control unit.
8 degrees/80 degrees
With a failure of the nosewheel steering system, the nosewheel will go into the ____________.
Free castering mode
Bumping or moving the nosewheel tiller after landing gear extension will interfere with a system test and cause the nosewheel steering to be: ____________.
Inoperative upon landing, with no advance warning to the pilot in flight
