(35 cards)
What does the amber AUTO BRAKE DISARM light indicate if it illuminates while arming the system for landing?
In this situation, a malfunction exists in the automatic brake system.
When is the use of flaps 40 recommended
Flaps 30 is normal setting for landing, but flaps 40 landings are recommended in the following situations:
- Negative {bracketed] OPC stopping margin under Min (2) for flaps 30
- Reported braking action is less than GOOD
- Wx is at or near mins for the approach to be flown
In order to meet AUTOBRAKE MAX OPC generated approximate stopping margins, Max manual braking must be initiated at what point?
Nose wheel touching down
Is landing authorized on a runway that has brackets around the Max stopping margin for a given flap setting?
NO
Choose another flap setting or runway that provides a positive stopping margin.
Can you safely initiate a rejected landing after reverse thrust deployment?
No
A go-around is not an option after the reverse thrust reverser levers are raised.
What would cause the landing gear handle to not move UP after takeoff?
Failure of the air/ground safety sensor of failure of the landing gear lever lock solenoid.
If the air/ground safety sensor has failed in the ground position, what indications might you have?
CDU will still display the Takeoff Reference page…
The intermittent warning horn will sound with the TE Flaps retracted…
and/or
Takeoff Configuration warning light will illuminate with the TE Flaps retracted.
What is the purpose of the landing gear lever lock solenoid?
Prevents the LANDING GEAR lever from being moved to the UP position while on the ground.
What is the purpose of the override trigger on the LANDING GEAR lever?
The trigger bypasses the landing gear lever lock.
How does the Manual Gear Extension Access Door affect operation of the landing gear in an NG?
If the Manual Gear Extension Access Door is open, normal landing gear extension is possible if System A pressure is available. Landing gear retraction is disabled.
If the Manual Gear Extension Access Door is open in an NG, will the landing lever move to the UP position?
YES
If the access door is open the gear lever would be able to be positioned to UP but all three landing gear would remain down and locked. In addition, all three red lights will be illuminated.
How does the Classic differ from the NG as it pertains to the Manual Gear Extension Access Door?
The Manual Gear Extension Access Door does no affect operation of the landing gear?
Where can you find the max landing gear extension / retraction speeds?
Placard on the forward panel near the gear handle
Retract - 235 KIAS
Extend - 270 KIAS
During landing gear retraction, what stops the wheels from spinning?
Main Gear wheels are stopped by the brakes.
Nose wheels are stopped by snubbers
If a main wheel tire is damaged on an NG during takeoff roll, braking of the main gear during retraction may be affected.
What protection is provided to prevent damage to components in the wheel well?
A fitting is provided in the wheel well ring opening.
If a spinning tire with loose tread impacts the fitting, the affected gear stops retracting and free falls back to the down position.
What happens when the LANDING GEAR lever is placed in the OFF position?
Hydraulic pressure is removed from the landing gear system.
In the CL, how can you verify the main landing gear position?
Main Landing Gear
- Use the viewer in the main passenger cabin located adjacent to the third window behind the aft overwind exit and one foot left of center.
~ You must lift the carpet to sight through the viewer.
~ The WHEEL WELL switch light switch should be placed ON
-
What visual indications are you looking for when checking the main landing gear via the viewer?
If the gear is down and locked the red paint stripes should be aligned on the down lock and the side struts.
How can you verify landing gear position in the NG?
The landing gear indicator lights on the overhead panel provide a verification of landing gear position.
How can the gear be manually extended?
Manual gear extension can be attempted by pulling the manual gear release handles on the floor of the flight deck.
What happens when the gear handles are pulled?
Pulling the handles releases the unlocks which allows the gear to free-fall to the down and locked position.
Is the gear warning horn still available after manual gear extension attempt?
YES
The landing gear warning horn is deactivated only when all gear are down and locked.
Is normal gear available after manual gear extension?
YES
Would have to do manual extension because of loss of system A. System B is still fine which powers normal brakes.
Is nose wheel steering available after manual gear extension?
Yes,
Unless the gear lever was stuck in the OFF position
