FIELD: complex testing of key transmitters of flying and navigation information, namely, of vertical reference and transmitters of angular velocities of aircraft. SUBSTANCE: device is predominantly employed to test instruments of light, maneuverable aircraft not carrying surplus meters on board. Essence of invention lies in determination of projections of absolute velocities of vectors oriented along horizontal axes via their projections in body axes system. Computation of these projections and check of relations by readings of vertical reference and transmitters of angular velocities make it possible to determine failure of instruments. EFFECT: increased reliability of device. 2 cl, 6 dwg
