The exact content of the Abnormal Procedures Section shall be determined by each Handbook producer, considering the design features of each airplane.

A. If the wheel temperature reaches as high as 177 deg., the core of safety plug shears off and the tire slips.

B. If the wheel temperature increases to more than 177 deg., the core of the fusible plug melts and the tire deflates.

C. The core of the filter element melts once the wheel temperature is above 177 deg., causing the tire to deflate.

A. Remove the sleeve to tighten the sliding tube.

B. Remove the sleeve to install the sliding tube.

C. Remove the sleeve to free the sliding tube.

A. Make sure that the cabin differential pressure is zero before you unlock the door.

B. Be sure that the variance of the cabin pressure is zero before you open the door.

C. Make certain that the difference of the compartment compression is zero before you open the door.

A. In order to avoid edge effects on vibration routes that may misinterpret test readings, the test pitot should be moved so that the detection route moves along the surface edge to provide a constant edge for the test pitot detection.

B. To avoid edge effects on vibration paths which give a test reading that may be misinterpreted, the test probe should be moved so that the inspection path follows the surface edge, giving a constant edge for the test probe to inspect.

C. The detector should be removed along the inspection route which follows the surface edge to provide an immobile edge to detect, so as to avoid the effects on vibration route edge which may lead to the misunderstanding of the test reading.

A. Move the sensor downstream and calculate the temperature again.

B. Move the probe downstream and monitor the temperature again.

C. Move the part downstream and measure the temperature again.

A. 描述飞机电源系统时，应说明线束保护功能。

B. 描述飞机电源系统时，应提供线路保护的描述。

C. 描述飞机电源系统时，应说明回路保护。

A. 不同的设计和复杂的型号使得飞机有一个重大的作用来决定特殊的失效是否更适合列举为“紧急”或“正常”程序。

B. 飞机的不同型号和机型的设计差异和复杂性，在决定某一特定故障是否更适合列为“紧急”程序或“异常”程序上发挥了重要的作用。

C. 各种型号的飞机的复杂设计差异很大程度能够决定特定失效是否能够更方便地列入“加急”或“反常”程序。

A. Unscheduled maintenance checks are those maintenance checks and inspections on the aircraft, its systems and units which are recognized by the manufacturer as special or unusual conditions which are not related to the time limits specified in -10 above.

B. For the unscheduled maintenance checks and inspections of aircraft, aircraft systems and components, the manufacturer shall not include special or unusual conditions from the time limits specified in -10.

C. If the unscheduled maintenance checks and inspections on the aircraft, its systems and units are special or unusual conditions, the time limits specified in -10 shall be referred to by the manufacturer＇s.

A. The Boeing-777 airplanes are different from the previous Boeing series ones mainly in that they are flown by wires.

B. The difference between the Boeing-777 airplanes and the subsequent Boeing series is that they are operated by wires.

C. Fly-by-wire is the main difference between Boeing-777 airplanes and the subsequent Boeing series.

A. 确保L和R PACK开关在P5-10空调面板上显示OFF位。

B. 确保P5-10空调面板上的L和R PACK开关处于OFF位置。

C. 确保P5-10面板上的L和R PACK在OFF位时，空调按钮在关闭位。
