A、 When the weight or torque of the aircraft change, illustrate how to keep this record in order to save the exact initial values to measure the weight and heavy center in normal flight.
B、 Explain how to maintain this record when changes to the weight or moments of the airplane are made so that accurate starting data is available to calculate the weight and center of gravity during normal operation of the airplane.
C、 When the changes to the mass or momentum occur, show the way to hold this record to get the beginning information easily to compute the mass and gravity core.

答案：B
A. Adapt the pressure connection to the pitot head.
B. Adjust the pressure connection to the pilot head.
C. Absorb the pressure connection to the pitot port.
A. The direction of tail wind is the same as that of the aircraft is moving.
B. The direction of tail wind is opposite to that of the aircraft is moving.
C. When the aircraft is flying with a tail wind, its speed over the ground is equal to its speed through the air, minus the speed the air is moving over the ground.

B. 由于对设备进行维修需要先完成其他维护工作。
C. 由于完成其他维护工作而需要对设备进行的维修。
A. When hydraulic system B engine drive pump pressure is under normal conditions, the hydraulic power transfer unit system supplies standby hydraulic pressure to the leading edge flaps and slats.
B. The hydraulic power transfer unit system is provide spare hydraulic pressure to the leading edge flaps and slats when hydraulic system B engine-driven pump pressure is abnormal.
C. The hydraulic power transfer unit system supplies alternate hydraulic pressure to the leading edge flaps and slats when hydraulic system B engine-driven pump pressure is below normal.
A. Use some auxiliary screws to assemble the unit temporarily
B. You shall use some additional screws to install the unit permanently
C. Temporarily disassemble this unit using some auxiliary screwdrivers.
A. Operators should negotiate with their local regulatory agency to adjust intervals to a best fit for their individual operational environments.
B. Airlines should consult local authority, the interval shall be adjusted although it best suits their unique operational environment.
C. In order to get the best intervals for their operational environments, operators should consult with local administration.
A. In order to do the engine bleed system leak check use APU to pressurize the system and check if there are leaks in the sensing tube and these system components.
B. The leak inspection of the engine bleed air system describes how to use APU to pressurize the system to inspect whether the sense lines and the system parts leak or not.
C. The way to check the leakage of the senses pipes and the system components by compressing system using APU is described.
A. In order to achieve the objective of providing the pilot with required, useful or desirable information concerning the operation of the particular airplane, in a form reasonably uniform throughout the industry,drafters of Handbooks shall follow the Specification to the extent practical.
B. In the cause of achieve the objective of offering the pilot with required, useful or desirable information concerning the operation of the particular airplane, in a form reasonably agree with throughout the industry,drafters of Handbooks have to after the Specification to the extent practical.
C. The drafters of the manual shall,to the extent practical,comply with this Specification for the purpose of providing the pilot,in a reasonably uniform form,with information necessary,useful or desirable in relation to the operation of a particular aircraft throughout the industry.
A. 对机场设备的持续投资,包括跑到、航站和技术,将确保源于空管系统更换和飞机机队的更新所带来的最大收益。
B. 对机场基础设施的持续投资,包括跑到、航站和技术,将确保源于空管系统更换和飞机机队的管理所带来的最大收益。
C. 机场基础设施的持续投资,包括跑到、航站和技术,将确保源于空管系统更换和飞机机队的更新所带来的最大收益。
A. In general, when describing the aircraft or its system, you should use third person such as there is shimmy damper on the nose wheel in order to prevent the wheel shimmying and rolling on the ground.
B. Generally speaking, third person should be used while describing the air craft or their system. For example the nose wheel is available on the shimmy damper so as to shimmy or roll on the ground.
C. Generally, in describing the airplane or its system, third person wording should be used. (For example: The nose wheel is provided with a shimmy damper to keep the wheel from shimmying while rolling on the ground. )
