游戏需要设定飞行路线，来安全引导特大喷气客机到大型跑道、引导小型螺旋桨飞机至简易跑道、以及引导直升机到直升机场。

The game involves setting flight paths to safely direct jumbo jets to the large runway, smaller prop planes to the airstrip, and helicopters to the helipad.

那么其他的一些飞行器，比如说直升飞机，螺旋桨飞机，他们没有喷气式引擎，可以在这种条件下飞行吗？

So can other aircraft, such as helicopters or prop-planes that don't have jet engines, fly through these conditions?

他的喷气流不需要螺旋桨，而是由一个两端开口的管子来实现。

His jet needed no propellers. It was a tube, open at both ends.
