Flashcards in Landing Gear Deck (49)
What is OFF position for for the landing gear?
Removes hydraulic pressure from the system.
The landing gear indicator lights indicate red when:
one or more of the gear is in disagreement with the lever or they are in transit. Lights also illuminate when the a/c is below 800' AGL with the gear not down and locked and one or both thrust levers are retarded to IDLE.
The landing gear lights show green when:
gear is down and locked.
Where is there another set of gear indicator lights?
Aft overhead panel. They operate from separate circuits.
T/F: Only one light, either center panel or overhead panel needs to be lighted for a gear to be considered down and locked.
Landing gear ______ and ________, as well as _______, receive power from hyd sys A.
extension, retraction, nose wheel steering.
T/F: Autobrakes are available with both normal and alternate brakes.
False. Just normal.
When anti-skid is inop, what can't you do for takeoff?
not able to use an assumed temperature reduced takeoff thrust takeoff.
How many air ground sensors are there?
6, 2 on each gear
On the _____, RTO mode is available.
After touchdown, and once wheel speed is greater than 30 kts, an _________ landing mode may be selected.
On the ground, the LANDING GEAR _____ solenoid is latched.
Flight locks(doors): when ___ or more entry /service doors are closed and either engine N2 RPM is greater than 50%, the flight locks become engaged.
Flight locks become disengaged on the ground when either thrust lever is less than _____.
Below 2000 feet RA the AT (provided armed) is available for a _______
AT are disengaged ______after touchdown.
With an airborne cargo fire, the _______extinguisher bottle timer is enabled.
If sys B resivoir fluid is lost due to a leak downstream of the landing gear transfer unit, a sensor closes the LGTU and alternate steering is ________.
The plane must be ________ for nose wheel steering to be powered.
on the ground
Nose wheel tiller inputs can be rotated up to
+/- 78 degrees.
Rudder pedals can supply steering control of up to
+/- 7 degrees
When does nose wheel steering deactivate?
on takeoff as the nose wheel strut extends
For aircraft _______ or ________ without having to depressurize the hydraulic systems, a lockout pin installed in the towing lever will depressurize nose wheel steering.
What hyd sys supplies pressure for the brake accumulator?
T/F: anti-skid is available with both normal and alt brakes.
What is the difference in anti-skid protection in normal vs alt?
Normal: anti skid for each individual wheel
Alternate: just wheel pairs.
Brake systems provide protection from what?
Skid, locked wheel, touchdown, hydroplanning.
T/F: Anti-skid is available with loss of both hyd systems
What hyd system provides pressure for autobrakes?
