Abstract
The invention relates to the technical field of pilotage aids for helicopters. In a speed measuring device having two measuring devices for longitudinal speed and lateral speed of the helicopter, each measuring device comprises a single sensor (9a, 9b) for sensing the position of the cyclic rotor pitch control along the axis concerned, and for sensing the acceleration component along the same axis. Each measuring device further includes a computer to provide the air speed components of the helicopter. Applications include flight testing, and the construction of firing computers and flight computers.
