A. Distances shown are based on weak wind.
B. Distances shown are developed with no wind.
C. Distances shown are on the basis of gentle wind.
解析：首先，这道题考察的是对风速对距离的影响的理解。在航空领域，风速对飞行距离有很大的影响。如果风速为零，那么所显示的距离就是在没有风的情况下测量的距离，也就是答案B所说的"Distances shown are developed with no wind"。
举个例子来帮助理解，想象一架飞机在没有风的情况下从A点飞往B点，飞行距离是100公里。但如果有风的话，飞机在风的影响下可能需要调整飞行路线，实际飞行距离可能会有所变化。因此，为了准确测量飞行距离，通常会以零风速为基准来显示距离。
A. The airworthiness problem needs to be resolved by the way any other airplane does in the operator＇s fleet has equal or more damaging corrosion, and it has to be done before the regular check of that zone.
B. The airworthiness problem needs immediate action ahead of the next planning inspection of that zone, because it would probably occur on another plane in the operator＇s fleet, causing equivalent or more serious corrosion.
C. Due to any other airplane in the operator＇s fleet could have the comparable or more vital corrosion, the airworthiness problem should be investigated immediately before the next periodic inspection of that zone.

A. Remove the test cap between the Precooler Control Valve and the 3908 sensor on the control pressure sense line and ensure that there is air flowing out of the port.
B. From precooler control valve to 3908 sensor, remove the sense line test cap, make certain that the air flows from the test hub.
C. The purpose of the test cap removal from the Precooler Control Valve to the 3908 sensor is to guarantee that there is airflow at the test port.
