How is the landing gear extended and retracted?
The nose and main landing gear can be retracted only during ground operations. The landing gear reach the full-down and extended position within 10 seconds and are locked in the down position by spring-loaded downlock bungees.
What happens when a temperature selector rotary knob is adjusted?
When there is smoke in the cabin. Q 30: What happens when a temperature selector rotary knob is adjusted? A: A signal is sent to the zone controller requesting a different temperature.
When should the landing gear be retracted?
Normally, the landing gear is retracted after lift-off when the airplane has reached an altitude where, in the event of an engine failure or other emergency requiring an aborted takeoff, the airplane could no longer be landed on the runway.
How does a landing gear retract?
A hydraulic landing gear retraction system utilizes pressurized hydraulic fluid to actuate linkages to raise and lower the gear. When the switch is moved to the UP position, hydraulic fluid is directed into the gear up line. The fluid flows through sequenced valves and down-locks to the gear actuating cylinders.
Why do the center tank pumps switch off automatically when the slats are extended for take off?
Why do the center tank pumps stop automatically when then slats are extended for takeoff? To keep the center of gravity as low as possible. During takeoff, the center tank fuel is gravity fed only.
What does pushing the APPR push button do? Arms the Flight Guidance system to capture a localizer and glide slope if the information has been entered into the MCDU. During a turnaround, you notice that ther is a residual ground speed on both NDs.
What kind of landing gear does an A320 have?
The A320 family aircraft are equipped with dual wheel main landing gear, which retracts inboard. Gears and main doors are hydraulically operated and electrically controlled by two computers named Landing Gear Control and Interface Units (LGCIU). The doors which are fitted to the landing gear struts are operated mechanically by the gear.
What should the speed of a landing gear be?
Landing gear operation is inhibited at speeds: · Below 100 knots. · Above 260 knots +/- 5 knots. · below 100 knots and above 260 knots. · Above 250 knots. 22. Can the gear be extended above 260 kts if necessary · Never.
Can a landing gear be extended above 260 KTS?
Can the gear be extended above 260 kts if necessary · Never. 23. How can the brake accumulator be re-pressurized · With the yellow electric hydraulic pump. · With the blue electric hydraulic pump.
Where is the gravity extension handle on a landing gear?
The landing gear gravity extension handle is located on the center pedestal. It mechanically operates the doors and gear. The steering hand wheels are located on each side of the cockpit, so either pilot can taxi the aircraft. They control the nose wheel steering through the BSCU.
