A. Because the inflation tests and material inspections can identify and condemn rafts which have more than minor installation defects, rafts which pass the tests and inspections may be in service for a period time with no fixed limit.
B. As the inflation tests and material inspections can affirm and declare the minor installation defects of the rafts, rafts checked by tests and inspections may come into service with no definition.
C. Rafts succeed in tests and inspections may keep the service indefinitely from a time that the inflation tests and material inspections identified and announced the rafts with many minor installation defects.

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 delivery of the aircraft is required to ensure its airworthiness, therefore it is subject to customer inspection procedures.
B. The airplanes are airworthy because they were delivered in accordance with advised inspection procedures.
C. The airplanes are delivered with mandatory inspection procedures to ensure their airworthiness.
解析：这道题考察的是飞机交付时的检查程序对于保证飞机适航性的重要性。正确答案是B选项：The airplanes are airworthy because they were delivered in accordance with advised inspection procedures.
解析：这句话的意思是飞机之所以适航是因为它们在交付时按照建议的检查程序进行了交付。这说明飞机在交付时已经经过了必要的检查和程序，确保了它们的适航性。因此，选项B是正确的。
举个例子来帮助理解：就好比你买了一辆二手车，但是卖家告诉你这辆车在交付时已经按照建议的检查程序进行了检查，所以它是适合上路行驶的。这样你就可以放心地驾驶这辆车，因为它在交付时已经确保了安全性。所以，飞机交付时的检查程序对于保证飞机的适航性非常重要。
