METHOD OF CONTROL OVER AIRCRAFT FLIGHT Russian patent published in 2013 - IPC F41G7/22 F42B15/00 

FIELD: aircraft engineering.

SUBSTANCE: stabilised sight line is consecutively aligned with every viewing object. Distance to objects and their angular coordinates relative to finder system are defined and memorised. After launching the aircraft toward short-range viewing object and its interception by control system, time of flight abeam flight path is measured. Data on aircraft hitting the preset viewing zone or miss is defined and fed to finder system field of vision. In the case of miss and possibility of re-aiming, instruction for flight above sight line is sent to aircraft. Sight line is switched to the next range viewing object and, at approach thereto, aforesaid instruction is cancelled to move the aircraft to sight line. In further misses, elevation instruction is fed with changing sight line to the nest viewing objects. Said elevation instruction is fed to aircraft when it flies over immediate object.

EFFECT: higher accuracy of control.
