High Altitude Operation

OBJECTIVE

The goal of this High Altitude Operations training (HIA) is to provide applicants knowledge of operating aircraft at high altitudes and high airspeeds, of the special physiological, equipment, and aerodynamic considerations involved in these kinds of operations. It also provides information to aid crews in becoming familiar with the basic phenomena associated with high-altitude and high-speed flight.
