GV Landing Gear Flashcards
How is the landing gear operated?
Landing gear is electrically operated hydraulically actuated for operation.
What hydraulic system is used for lowering and raising the landing gear?
The left hydraulic system.
The PTU can be used if the hydraulic system fails
Lastly the gear and be extended using compressed nitrogen
What are the limits of the nosewheel steering?
80° left and right
What are the limits of nosewheel steering through the rudder peddles
Left and right 7°
What charges the parking brake?
Dual chamber cylinder with nitrogen pressure at 1200 psi and hydraulic pressure from the Aux system at 3000 PSI
At what speed will antiskid take effect?
Above 8 knots
The D spin feature decelerates the gear in
Three seconds
In order to move the landing gear handle it must be pressed to….
Press to the left prior to movement.
When will the gear unsafe warning horn and light illuminate?
- At 350 feet AGL with thrust levers less than 5° - horn can be silenced
- Flaps set greater than 22° - Horn can not be silenced
Pulling the emergency landing gear handle….
- Moves the dump shuttle valve that cuts off all hydraulic fluid to gear extension system
- Opens nitrogen release valve that ports high-pressure to gear extension
- Blue dump caption will illuminate
What is the minimum pressure for the parking brake?
1700 psi
Where can break accumulator pressure be read?
On the accumulator brake synoptic page
Break accumulator gauge on copilots forward panel
During preflight The AUX pump is tested by…..
Arming the AUX pump and depressing brake pedals beyond 10°
With the PTU and AUX system armed prior to taxi the left hydraulic system will power the brakes.
If the left hydraulic PUMP fails the PTU will automatically provide pressure
If the left hydraulic system fails what will activate breaks?
Emergency brake accumulator by pulling the parking brake handle
Maximum airspeed for gear operation?
Maximum airspeed with gear extended?
225 knots
250 knots
