| 1. | The same considerations apply to the correct banking angle of a plane when it makes a turn in level flight .
当水平飞行的飞机转弯时，同样应有一定的倾斜，倾斜角的大小可按与上面相同的考虑来决定。
|
| 2. | Okay , adjust for the wind . nice , level flight
好，适应一下风向不错，平飞
|
| 3. | Okay , adjust for the wind . nice , level flight
好，适应一下风向不错，平飞
|
| 4. | The aircraft is lost control now , i can not maintain level flight at present altitude
飞机现在失去操纵，我在现在的高度上不能保持平飞。
|
| 5. | We will stop dumping for the time being , the dumping must be carried out at straight level flight
我们将暂时停止放油，放油必须要一直平飞。
|
| 6. | From straight and level flight , after the helicopter passes the pilot , execute a 180 degree turn away from the pilot
先保持水平直线飞行，当直升机通过操控者后，开始执行外侧180转弯的动作（远离操控者） 。
|
| 7. | Starting from straight and level flight after the helicopter passes the pilot , the helicopter is smoothly pulled vertical ( aft cyclic )
先保持水平直线飞行，当直升机通过操控者后，开始平滑地拉高机头（打升舵） ，使机头朝上垂直爬升。
|
| 8. | Starting from straight and level flight after the helicopter passes the pilot , the helicopter is smoothly pulled through a loop ( aft cyclic )
先保持水平直线飞行，当直升机通过操控者后，开始平滑地拉高机头（打升舵） ，使飞行轨迹成为一个环状。
|
| 9. | The helicopter is allowed to fall the same distance that it climbed at the beginning of the maneuver before pulling the helicopter back to straight and level flight
待直升机垂直俯冲的距离与垂直爬升的距离相同时，拉起机头恢复成水平直线飞行。
|
| 10. | Based on the mathematical model developed by the paper , the trim calculations are carried out in the conditions that the example aircraft converts from helicopter to airplane mode in level flight with zero longitudinal acceleration and angular rate
本文依据所建立的样例机纵向动力学模型,假定飞机在给定高度平飞,纵向加速度和角加速度均为零,完成过渡模式下的动力学配平。
