Exercise 15. Translate the text . Put 3 key questions on it.

Text 3. System Interface - Brake System

Braking is provided by four brake assemblies located on the main gear wheels. The brakes are applied either manually using brake pedal input or automatically using the autobrake systems. In either case, the antiskid system, using normal or alternative antiskid valves, is used to modulate brake pressure to optimize braking for any given runway condition. The controls for the antiskid and autobrake systems are located on the panel, adjacent to the landing gear selector lever. The parking brake permits setting the brakes when the airplane is parked or moored. A red light on the control stand indicates when the parking brake is set.

Exercise 16. Translate text 4 and entitle it.

Text 4

The landing gear hydraulically actuated to extend and retract by means of a Landing gear selector lever, is placed in the UP position, all three gears retract. Each main gear retracts inboard into the fuselage. The nose gear retracts forward into the nose wheel well. When the selector lever is placed in the DOWN position, all three gears extend. The OFF position is the normal cruise mode and ail Landing gears are locked up and depressurized. A solenoid Lock system restricts the selector lever from being placed in the UP position when the airplane is on the ground.

Six Lights Located above the Landing gear selector lever provide indication and warning for the Landing gear. A green light is illuminated when the respective gear is down and locked. The red light is illuminated when the Landing gear is in transit or the Landing gear lever and the Landing gear do not agree. The red lights also serve as warning lights when the airplane is in a possible Landing configuration and the gear is not down and locked.

Three red manual extension handles are located on the floor of the flight compartment, just aft of the first officer's station, for manual extension of the Landing gear in case of hydraulic malfunction in system 'A', the manual extension handles are independently operated for each gear. The Landing gear selector lever should be in the OFF position for manual extension.
