单选题最大操作限制速度是指在正常飞行操作中不得故意超过的速度限制。V用节表示，M用马赫数表示。

A、Maximum Limiting speed Unsticks is the speed restrain which will not be intentionally surpassed in typical flight operations. V is communicated in knots and M in Mach Number.

B、Maximum Restriction Speed is the fastest a plane can fly without breaking the rules in normal flight. The speed is measured in knots and Mach Number.

C、Maximum Operating Limit Speed is the speed limit that may not be deliberately exceeded in normal flight operations. V is expressed in knots and M in Mach Number.

单选题操作测试相关描述对应的英文是以下哪个？

A、Operational Test: That procedure required to ascertain only that a system or unit is operable. These tests should require no special equipment or facilities other than that are installed on the aircraft and should be comparable to the tests performed by the flight crew. It is not intended that the operational test of the unit shall meet the specifications and tolerances ordinarily established for overhaul, or major maintenance periods.

B、On pressurized aircraft, the cabin air is distributed with a system of air ducts leaded from the pressurization source into and throughout the cabin. Typically, air is ducted to and released from ceiling ventilation.

C、Crucial angle of attack is the angle at which a stream or air flow begins to split from a surface,causing a decrease in efficiency. It is important for designing dynamic surfaces ,such as airplane wings,turbine blades,as it determines the maximum attack angle that can be achieved without causing loss of lift or thrust.

单选题地面慢车功率指满足飞机以最小推力在地面尽可能慢地运行，但足以保证发动机、发动机附件和飞机正常运行所需的发动机功率。

A、Ground Idle Power refers to the power required to run an engine on the ground, as slowly as possible, yet sufficient to ensure satisfactory engine, engine accessory, and airplane operation with a minimum of thrust.

B、Ground Idle Power refers to the power required to run an engine as slowly as appropriate on the ground while still ensuring satisfactory airplane operation with a maximum of thrust of engine and engine accessory.

C、For Ground Idle Power, it determines the minimum power necessary to initiate and maintain safe airplane operation, engine accessory function, and satisfactory engine performance while limiting the degree of thrust utilized.

单选题在某些涡轮螺旋桨驱动的飞机上，状态杆是发动机启动和停车的主要控制装置。在其它类型的飞机上，状态杆主要用来控制设置发动机和螺旋桨速度。

A、On some turbopropeller powered airplanes, the condition lever is the primary control for starting and stopping the engine. On others, it is the primary control used to set engine and propeller speed.

B、On some piston powered airplanes, the condition lever is the secondary control for starting and shutting the engine. On others, it is the secondary control used to set engine and piston speed.

C、On some turbopropeller powered airplanes, the status lever is the secondary control for starting and shutting the engine. On others, it is the secondary control used to set engine and propeller speed.

C、Critical angle of attack is the angle at which a fluid or air flow begins to separate from a surface, causing a reduction in the efficiency of the flow. The critical attack angle is an important consideration in the design of aerodynamic surfaces, such as airplane wings, turbine blades, as it determines the maximum angle of attack that can be achieved without causing a loss of lift or propulsion.
