Title: Define terms related to airspeed.
Course: Aircraft Pilot Training I (20053-I) > Section: Examining Aircraft Instruments, Components, Systems, and Performance

Definitions should include the following:

- Equivalent airspeed (EAS)—the ASI reading corrected for position (or installation), for instrument error, and for adiabatic compressible flow for the particular altitude
- Velocity of normal operations (V_NO)—the maximum speed for normal operation or the maximum structural cruising speed. This is the speed at which exceeding the limit load factor may cause permanent deformation of the aircraft structure.
- Velocity to never exceed (V_NE)—the speed that should never be exceeded; if flight is attempted above this speed, structural damage or structural failure may result.
