FIELD: aviation; air navigation; prevention of collision of flying vehicle with underlying surface of Earth.
SUBSTANCE: during flight, signals of relief of underlying surface of Earth are shaped by observation from flying vehicle; signals corresponding to relief of underlying surface recorded in data base are also used; signals are shaped on flying vehicle display at aspect angles corresponding to aspect angle of observation, after which signals are compared and in case of deviation, correction is made on display.
EFFECT: enhanced safety of flight.
