2011 Cqt-landing Gear And Brakes

The normal braking system receives its hydraulic power from the hydraulic system. This system uses hydraulic fluid to transfer force from the brake pedal to the brake calipers, which then apply pressure to the brake pads and create friction against the rotors. This hydraulic power allows for efficient and effective braking, as the force applied to the brake pedal is amplified by the hydraulic system to provide the necessary stopping power.

The solenoid sequence valve receives its signal to open or close the gear doors from the PSEU. This means that the PSEU controls the operation of the solenoid sequence valve, which in turn controls the gear doors. Therefore, the statement is true.

The anti-skid system is not available when using the emergency brake. The emergency brake is a mechanical system that directly applies pressure to the brake pads or shoes, bypassing the anti-skid system. This means that when the emergency brake is engaged, the wheels can lock up and skid, leading to a loss of control. Therefore, the correct answer is "No".

The emergency parking brake receives its hydraulic pressure from the hydraulic system.

The LDG GEAR INOP caution light requires an alternate gear extension. This means that if the LDG GEAR INOP caution light illuminates, the pilot must use an alternate method to extend the landing gear. This could include using a manual gear extension procedure or relying on backup systems to lower the gear.

The gear lever lock release button must be held down when making a gear selection. This button is designed to prevent accidental gear changes and ensure that the driver intentionally selects the desired gear. Requiring the button to be held down adds an extra layer of safety and helps prevent any potential mishaps while shifting gears.

The brakes are available immediately after touchdown when the anti-skid system is on and operating. Additionally, the brakes are also available 2.5 seconds after touchdown when the wheel spin-up reaches 35 kts. Therefore, both options A and B are correct.

The rudder pedals provide approximately 7 degrees of nosewheel steering either side of center with the nosewheel steering turned on. This means that when the pilot uses the rudder pedals, they can turn the nosewheel up to 7 degrees to the left or right from its center position.

During an alternate gear extension, if the landing gear fails to free-fall to the down and locked position, the main and nose gear cannot be manually pumped down.

The nose wheel free-caster is the mechanism that allows the nose wheel of an aircraft to rotate freely. It is typically set at an angle to the centerline of the aircraft, which helps with steering during taxiing. In this case, the correct answer of 120 degrees indicates that the nose wheel will be positioned 120 degrees to the left or right of the centerline.

The tiller provides 60 degrees of nosewheel steering either side of center.

During ground testing, the anti-skid lights stay on for 6 seconds. This duration allows the tester to observe and analyze the performance of the anti-skid system. Holding the switch for an indefinite period of time is not necessary as the 6-second duration provides sufficient time to evaluate the system's functionality.

With the accumulator charged to 3000 psi, the braking system is capable of providing approximately four brake applications. The accumulator stores hydraulic pressure that is used to engage the parking brake. Each brake application requires a certain amount of pressure from the accumulator, and with it charged to 3000 psi, it is able to provide enough pressure for approximately four brake applications.

The LDG GEAR INOP caution light indicates a failure associated with the Solenoid Sequence Valve.

The landing gear warning horn can be muted when the airspeed is below 130 kts, one power lever is near flight idle, and the gear is not down and locked.

The PSEU (Proximity Sensor Electronics Unit) is responsible for monitoring the position of the uplocks, downlocks, and gear door positions. It uses proximity sensors to detect the position of these components and provides feedback to the aircraft's systems. The PTU (Power Transfer Unit) is not involved in monitoring these positions. The Solenoid Sequence Valve and WOW Sensor are also not directly related to monitoring the position of the uplocks, downlocks, and gear door positions. Therefore, the correct answer is PSEU.

The landing gear warning horn will sound when the following conditions are met: autofeather is not armed, flaps are greater than 15, power levers are not at take-off, and the gear is not down and locked. Additionally, the horn will also sound if the airspeed is less than 130 kts, the gear is not down and locked, and the power levers are near flight idle. Therefore, the correct answer is A & C.

After a normal extension, the aft nose gear doors and forward main gear doors remain open.
