FIELD: complex monitoring of flight information sensors, including pitch sensors (horizon sensors), velocity transducer and longitudinal acceleration sensors. SUBSTANCE: device has differentiator, comparator and indicator connected in series and three-input adder whose first subtracting input is connected with differentiator input whose input is connected in its turn to velocity transducer output, second adding input is connected with output of longitudinal acceleration sensor and third subtracting input is connected with angle output or angle sine output of pitch sensor. Estimation of longitudinal g-load calculated according to readings of pitch sensor and velocity transducer is compared with magnitude measured by means of longitudinal acceleration sensor. EFFECT: enhanced efficiency and accuracy of monitoring. 3 cl, 3 dwg
