Airframe 10 (MLG2)

What action should be taken whenever maintenance is performed that will affect the landing gear system performance?. A test flight should be performed to conduct an operational check. A technician with an inspection authorization should perform a visual inspection. The aircraft should be placed on jacks and a retraction test should be performed.

Debooster cylinders are used in brake systems primarily to. reduce brake pressure and maintain static pressure. relieve excess fluid and ensure a positive release. reduce the pressure to the brake and increase the volume of fluid flow.

What would be the effect if the piston return spring broke in a brake master cylinder?. The brakes would become spongy. The brake travel would become excessive. The brakes would drag.

On an air valve core stem, what indicates high-pressure type?. An embossed letter 'NP'. An embossed letter 'HP'. An embossed letter 'H'.

The purpose of a sequence valve in a hydraulic retractable landing gear system is to. Prevent heavy landing gear from falling too rapidly upon extension. Provide a means of disconnecting the normal source of hydraulic power and connecting the emergency source of power. Ensure operation of the landing gear and gear doors in the proper order.

How is it determined in a master cylinder brake system that all of the air has been purged from the system?. By operating a hydraulic unit and watching the system pressure gauge for smooth, full-scale deflection. By depressing the brake and noting that the brake is firm and not spongy. By measuring the amount of fluid return to the master cylinder upon brake release.

Excessive wear in the center of the tread of an aircraft tire is an indication of. Misalignment. Underinflation. Overinflation.

Antiskid braking systems are generally armed by. the application of brakes. a switch in the cockpit. the rotation of the wheels above a certain speed.

If an aircraft shock strut (air/oll type) bottoms upon initial landing contact, but functions correctly during taxi, the most probable cause is. low fluid. low air charge. a restricted metering pin orifice.

Refer to Figure 20.) What is the minimum circumstance that will cause the landing gear to move to indicate an unsafe condition?. All gears up and one throttle retarded. Any gears up and both throttles retarded. Any gear not down and locked, and one throttle retarded.

In shock struts, chevron seals are used to. absorb bottoming effect. prevent oil from escaping. serve as a bearing surface.

If the extended longitudinal axis of the main landing gear wheel assembly intersects aft of the aircraft, the wheels can be termed as having. toe-out. toe-in. Negative camber.

A close inspection of a fuse plug reveals the core has experienced some deformation. What is the appropriate maintenance procedure?. Replace all the fuse plugs. Replace the affected fuse plugs. Replace with a new wheel assembly.

The fusible plugs installed in some aircraft wheels will. Indicate tire tread separation. Prevent overinflation. melt at a specified elevated temperature.

At what point in the landing operation does normal skid control perform its function?. When wheel rotation deceleration indicates an impending skid. When wheel rotation indicates a hydroplaning condition. Anytime the wheel is rotating.

In a brake antiskid system, when an approaching skid is sensed, an electrical signal is sent to the skid control valve which. acts as a bypass for the debooster cylinders. relieves the hydraulic pressure on the brake. equalizes the hydraulic pressure in adjacent brakes.

Nose gear centering cams are used in many retractable landing gear systems. The primary purpose of the centering device is to. align the nosewheel prior to touchdown. engage the nosewheel steering. center the nosewheel before it enters the wheel well.
