JOINT U.S./FRANCE INVESTIGATION OF HELICOPTER FLIGHT ENVELOPE LIMIT CUEING

Under the auspices of a memorandum of understanding (MOU) for cooperative research in helicopter aeromechanics, a joint program has been performed by the U.S. Army and the French Ministry of Defense to investigate methodologies for aiding the helicopter pilot in avoiding flight envelope limits. A series of piloted simulation experiments were conducted using the NASA Ames Vertical Motion Simulator and the Eurocopter France SPHERE simulator to investigate cueing algorithms and cueing modalities including head-up display symbology, panel mounted display symbology, aural tones, automated voice warnings, and inceptor force feedback.
