Relative speed gauge for controlling an unmanned air vehicle

摘要

The device has a display and a receiving unit for receiving data of two vertical absolute speed (V1, V2) originating from an aircraft (10). A calculator generates a graduated speed gauge on the display, where the gauge comprises a fixed cursor indicating a value of the former speed, a moving cursor indicating a value of the other speed and another moving cursor indicating a setpoint. Graduation of the gauge is centered around the value of the former speed.
