What happens if an uplock is found in wrong position during preflight and AUX pump pressure is applied?
Below what speed is antiskid protection no longer available?
The nose landing gear drag brace provides additional support and is attached to the fuselage structure at the aft end of the nose wheel well and nose landing gear strut. The drag brace forces the nose landing gear down and forward during extension.
The drag brace forces the nose landing gear up and forward during retraction.
What is the purpose of landing gear LOCK RELEASE button?
What is the position of landing gear doors following an emergency extension?
During ground operations, if the parking brake is used, selecting the AUX pump 'ON' will only recharge the Left Inboard Parking Brake accumulator. This action will:
Landing gear position indicators and an audible warning system are incorporated to provide positive indications of the position of the landing gear. A Weight-On-Wheels (WOW) system is included in the landing gear system, to furnish 'ground' or 'air' mode reference signals to various aircraft systems during ground maintenance. Each gear incorporates _____ for movement.
A Landing Gear Control Maintenance Panel is provided to operate the gear doors for preflight purpose and landing gear and door operation for maintenance functions.
The two accumulators located aft of the main wheel well supplies hydraulic pressure for the parking brake system. Lifting up on the parking brake handle opens the parking brake valve, which release the hydraulic pressure stored in the left accumulator and directs the pressure to the outboard brakes.
It releases the hydraulic pressure stored in the left accumulator and directs the pressure to the inboard brakes. The pressure will also be ported to the repeater valve. The repeater valve, ports right accumulator pressure to the outboard brakes. Pressure loss between the inboard and outboard brakes through the repeater valve is less than 200 psi.
If the flap position is greater than 22 degrees, the warning horn can only be silenced by:
The BRAKES synoptic page displays applied pressure and temperature for each brake. Brake synoptic page pressure range is from 0 to:

The emergency extension system may only be used once and cannot retract the landing gear.
For emergency landing gear extension purposes, there is one nitrogen bottle located in the wheel well bay.
There are 2 bottles which are interconnected and located on the forward left and forward right side of the nose wheel well. Their combined capacities provide enough nitrogen pressure to emergency extend (blow down) the landing gear. The nominal pressure on a fully serviced emergency landing gear extension bottle is 3000 psi.
What should nose wheel strut extension be during pre-flight?
Crew Alerting System (CAS) Messages – The blue L-R INBOARD BRAKE DEGRADE' message is displayed when the inboard wheel speed sensor is inoperative.
What is the purpose of the brake fuses?
For takeoffs rejected at or below _____ wheel speed, a constant brake pressure of 600 psi is applied to all four main landing gear (MLG) brake assemblies.
What happens when you depress either DUMP VALVE switch?
CAS messages associated with landing gear and/or door position are not presented until _____ after the landing.
At which radio altitude will the audio warning horn alert the crew that the landing gear is not down and locked?
Depressing the HORN SILENCE button on the landing gear control panel silences the landing gear warning tone (provided flap position is less than 22 degrees).
How are gear failures depicted on flight control synoptic page?

The Landing Gear Control Maintenance Panel (LGCMP) is used to open/close gear doors.
Maintenance can change WOW status, retract or extend the gear. In maintenance mode, gear handle input is ignored.
Each MLG wheel has a dedicated brake assembly which functions as normal toe brakes and parking brakes. What other functions do they perform?
After performing an emergency extension, a blue DUMP legend illuminates inside both DUMP VALVE switches. What does this indicate?
The landing gear is electrically controlled, hydraulically actuated, and electrically sequenced.
If the LGCU does not detect that the doors are in the OPEN position the landing gear will not retract.
Crew Alerting System (CAS) Messages – The amber 'BRAKE OVERHEAT' message is displayed when one or more brake assemblies has exceeded temperature limit of:
There is one Weight-On-Wheels (WOW) sensor installed on each landing gear. The WOW sensors provide the ground or air mode reference signals to the Landing Gear Control Unit (LGCU), which in turn provides the WOW status to various aircraft systems.
Two Weight-On-Wheels (WOW) sensors are installed on each landing gear.
In the event of a rejected takeoff, the pilot should apply manual braking regardless of the RTO mode selection.
What is the meaning of magenta gear indication on flight control synoptic page?
When parking brake handle is set, what component ensures the pressure coming from outboard accumulator is equal to or slightly less than pressure coming from inboard accumulator?
A repeater valve is located behind the right main wheel well bulkhead. The valve supplies metered pressure to the outboard brakes (based on the corresponding input from the parking brake valve). The parking brake valve provides left accumulator pressure to the repeater valve. The resulting pressure positions a piston which acts on a set of springs, repositioning another piston which allows right accumulator pressure to be ported to the outboard brakes. The repeater valve is designed so the left and right hydraulic systems are not mixed.

To set the parking brake, the handle must be lifted to approximately ____.
At 65 degrees, the handle will be locked in the set position.
