The physical causation of the optimal trajectory and the corresponding angleofattack profile are presented. It is a good reference for schematic trajectory design for gliding type reentry vehicles.

分析了沿最优轨迹飞行的物理原因和基本迎角控制规律，可为滑翔式再入飞行器的最优轨迹方案设计提供依据。

The data is then analysed to produce a schematic read-out for immigration officials that shows the risk profile for every single passenger on an incoming flight, seat by seat, high risk to low risk.
