Description

A large number of modern jet aircraft, of all sizes and including Very Light Jets (VLJs)s, routinely cruise at high altitudes.

The record of Accidents and Serious Incidents which have accompanied this increase in high-altitude flight has suggested that pilot understanding of the aerodynamic principles of safe high-altitude flight may not always have been sufficient. This applies particularly to attempts to recover from an unexpected loss of control. The subject is introduced in this article and covered in comprehensive detail in the references provided.
