Brakes & Landing Gear Flashcards
What is the function of the landing gear transfer valve during gear retraction when #1 engine RPM drops below a limit value that is less than idle
?
When does the landing gear transfer unit operate (aircraft airborne)
?
How is wheel rotation stopped during gear retraction
Nose wheel by snubbers and main wheels by auto- hydraulic braking
How is the landing gear extended manually
Individual manual extension handles release up locks
Which conditions are necessary to use the nose wheel steering
“A” system pressurized, gear lever in DOWN position, nosewheel steering switch NORMAL
Which hydraulic system supplies pressure for normal brakes
System “B” for all main wheel brakes
How does the ANTI-SKID system control normal braking when a single wheel skid is detected
Modulates pressure to the individual wheel brake
Autobrakes are available with a system “B” failure as long as the alternate brakes are operational
False
What does a momentary AUTO BRAKE DISARM light indicate when RTO mode is selected
Successful automatic self- test
A successful test of the Autobrake RTO feature is indicated by
After the RTO position is selected, the AUTO BRAKE DISARM light illuminates briefly and extinguishes
What occurs during a rejected takeoff between 60 and 90 knots with RTO selected
Autobrakes will not be applied; AUTO BRAKE DISARM light illuminates
Autobrakes may be disarmed after landing by
All answers are correct
What occurs if a landing is made with RTO selected
No automatic braking, AUTO BRAKE DISARM light comes on
When would braking with only accumulator pressure occur
With loss of “A” and “B” system hydraulic pressure
What is the hydraulic pressure source for the alternate brake system
Hydraulic system “A”
How is the alternate brake system activated
Automatically when “B” HYD pressure is low
While setting the parking brakes, the ANTI-SKID INOP light illuminated. This indicates
A malfunction in the parking brake system
Auto Brakes are available
With “B” system pressure
Brakes should not be applied until after touchdown
True
A Landing Gear Transfer Unit provides a backup hydraulic power source to
Retract the landing gear in the event #1 engine fails on takeoff
What is the maximum speed at which a pilot may extend the landing gear
270 kts
Is the RTO position of the autobrakes required for takeoff if the autobrakes are operational
Yes
A check of the brake wear indicators is valid when the parking brake is
Set with hydraulic pressure
When the aircraft is towed, the ____ should be off or a steering lockout pin must be installed
“A” system pressure
With failure of both “A” and “B” hydraulic systems, approximately what will the brake pressure indicator read when no more accumulator braking is available
1000 psi
What is the maximum nosewheel turning angle in either direction that can be commanded by the rudder pedals
7 degrees
In flight , with the landing gear up, a warning horn that can not be silenced with the HORN CUTOUT will sound
Anytime the flaps are at 25 degrees
What is the maximum speed at which the pilot may retract the landing gear
235 kts
The gear is down and locked with three green lights. What is the speed limit
320 kts
When must the autobrake RTO feature be selected
For all takeoffs with autobrakes operative
