Landing Gear Flashcards
Recall the function of Gear Horn button
The landing gear warning horn and vocal
warning will sound in the following conditions:
• Landing gear is not down and locked with flaps extended in the landing range (cannot be silenced).
• Landing gear is not down and locked,
throttles retarded, airspeed is less than 210 KIAS, and altitude is below 1200 feet (may be silenced)
Recall primary and secondary gear position indications
Landing gear positions are indicated by the primary gear position lights and/or the secondary landing gear position indicators on the CONFIGURATION synoptic
A set of three green gear light indications on either the gear position lights on
the instrument panel or the gear position indicators on the CONFIGURATION
synoptic constitute a gear down and locked confirmation
Recall the maximum brake temperature for takeoff without referring to the ODM.
Brake temperature must not exceed 115°C for airport elevations up to 2,200 feet MSL.
Temperature limits are based on a 120K pound aircraft and a V1of 140 knots. To
confirm actual brake temperature limits based on different conditions, reference ODM
Recall indications of a brake overheat (3)
After landing, brake temperature
differential up to 60°C on the same gear
is considered normal
Master Caution Light
BRAKE OVERHEAT on EAD
BRAKE OVERHEAT on CONFIG SD w/ boxed temp in amber.
Recall indications of Low Brake Pressure (3)
Master Caution Light
BRAKE PRESSURE LO on EAD
BRAKE PRESSURE LO on CONFIG SD w/ pressure boxed in amber.
Recall how to determine the Parking Brake is set
• The parking brake is set by pushing the brake pedals, lifting the PARK BRAKE
knob and releasing the brake pedals
• When the parking brakes are set, the PARK BRAKE ON alert is displayed on the
EAD
Recall aircraft turn capabilities with the nose gear steering wheel and rudder pedals
Nose Gear Steering Wheel – Overrides the rudder pedal steering and provides up to 82 degrees of turn in either direction
Rudder Pedals – Full deflection provides up to 17 degrees turn capability in either direction
Recall features of the aircraft Ground Shift Sensing system
- Located on aircraft nose gear
- Signals various airplane systems as to whether the airplane is on the ground or in flight
- Inability to raise the gear due to a failed ground shift sensor can be overridden after takeoff by the GEAR HANDLE RELEASE button
Push and Hold – Landing gear handle can be raised in the
event of a ground shift system malfunction after takeoff
Recall the location and operation of the Emergency Gear Extension Lever
The emergency gear extension lever is located in the floor on the right side of the pedestal and is used to extend the gear if the normal method fails
When the lever is raised and latched, the landing
gear will free fall to the down and locked position
Recall Cautions associated with ground operations when landing after an Emergency Gear Extension.
- When the Emergency Gear Extension Lever is raised, the right hydraulic system is isolated from the landing gear. As a consequence, although steering is available in both directions, nose gear steering is limited in turn deflection to the left (no right push cylinder), even when both hydraulic systems are operating
- Stop airplane on runway
- Close and latch the main gear doors manually
- Verify landing gear pins are installed prior to taxi or tow
Recall how braking is effected with a loss of both hydraulic systems
• Each main gear wheel is equipped with disc-type brakes operated by two
independent hydraulic brake systems
• Both hydraulic brake systems power each brake assembly
• Should both hydraulic systems fail, each system is equipped with an accumulator of sufficient capacity to provide brake pressure to stop the airplane
Recall features of the antiskid system
- Allows maximum wheel braking without skidding the tires
- Prevents brake application until after main wheel spinup
- Automatically disabled at low taxi speed
- Automatically tested when power is applied
Recall the function of the ANTISKID switch (ON, OFF)
ON – Activates antiskid system
OFF – Deactivates antiskid system
ANTISKID OFF does not indicate
failure; it indicates the system is
selected off
Recall indications of an Anti-Skid failure (4)
- Master Caution
- Boxed amber ANTI SKID L FAIL/ANTI SKID R FAIL on EAD and CONFIG SD along with ANTI SKID OFF (not boxed)
- ANTI SKID FAULT on STATUS SD
