A. Bleed the hydraulic system.
B. Pressurize the hydraulic system.
C. Depressurize the hydraulic system.
A. Ensure that you do activate the control adjacent to it.
B. Adjust the adjacent control for optimal results.
C. Make sure that you do not operate the adjacent control.
A. 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.
B. Crutial angle of attack is the angle at which a stream or air flow begins to seperate from a surface,causing a decrease in efficiency.It is important for designing aerodynamic surfaces ,such as airplane airfoils,turbine blades,as it determines the maximum attack angle that can be achieved without causing loss of lift or thrust.
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.
A. This is the maximum portion of flammable vapors in air.If the portion is bigger,when an ignition source touched the gas,it would cause the fire to be diffused.
B. This is the minimum volume of flammable vapors.If the volume is lower,when the gas contacted with an ignition source,the fire would not come out.
C. This is the minimum density of flammable vapors in air.If the density was lower,when an ignition source touched the gas,it would not cause the spread of flame.
A. 在某些情况下,延长检查频率可能会对疲劳检查造成不足,从长远讲会造成实际飞行小时数低于最初预测。
B. 在某些情况下,如果数据表明疲劳问题发生在比最初预测的飞行小时数更多,则可以放缓检查频率。
C. 在某些情况下,延长实际飞行小时将影响疲劳检查,因此会造成维修检查的小时数远低于最初预测。
D. B.在某些情况下,如果数据表明疲劳问题发生在比最初预测的飞行小时数更多,则可以放缓检查频率。
E. C.在某些情况下,延长实际飞行小时将影响疲劳检查,因此会造成维修检查的小时数远低于最初预测。
