FIELD: avoidance of collisions of flying vehicles equipped with main rotors with power lines and other physical obstacles. ^ SUBSTANCE: proposed system includes visual display, GPS receiver and altimeter for indication of position and heading of flying vehicle. Computer determines the first dangerous zone within first distance from flying vehicle selected beforehand and first color image of first dangerous zone is formed on basis of digital chart data. Computer reveals also more dangerous zone within the second distance from flying vehicle selected beforehand which is lesser than the first distance and second color image of more dangerous zone is formed. Then, system finds physical obstacle located within the third distance from flying vehicle selected beforehand which is lesser than the first one and signal is sent for forming the signal on warning device which forms series of audible clicks whose frequency and/or loudness increases at approach to obstacle. Provision is also made for sound muting sub-system and audible alarm signal instead of muted audible signal and muting interlocking unit. ^ EFFECT: low cost and enhanced reliability. ^ 6 cl, 6 dwg |
