Title: Describe a height-velocity diagram.
Course: Aircraft Pilot Training II (20053-II) > Section: Examining Atmospheric and Meteorological Conditions

Description should include the following:

- The height-velocity diagram depicts altitude and airspeed situations from which a successful auto-rotation can be made.
- The time required, and therefore, altitude necessary to attain a steady-state, auto-rotative descent is dependent on the weight of the helicopter and the density altitude.
