DEVICE FOR DETERMINATION OF AIRCRAFT-TO-AIRCRAFT DISTANCE Russian patent published in 2005 - IPC

FIELD: aeronautical engineering; determination of aircraft-to-aircraft distance.

SUBSTANCE: aircraft-to-aircraft distance is determined by the following formula: where position of first of first aircraft is defined by azimuth α₁, slant range d₁, altitude h₁ and position of second aircraft is determined by azimuth α₂, slant range d₂ and altitude h₂. Proposed device includes aircraft azimuth indicators (1,4), flying altitude indicators (2,5), indicator of slant range to aircraft (3,6), adders (7, 14, 15, 19), multiplication units (8-12, 16, 18), cosine calculation unit 913), square root calculation units (17-20) and indicator (21).

EFFECT: avoidance of collision of aircraft; enhanced safety of flight due to determination of true aircraft-to-aircraft distance with altitude taken into account.
