METHOD OF FLIGHT MODELLING OF MANUAL VISUAL LANDING OF AIRCRAFT ONTO OBJECT Russian patent published in 2012 - IPC G01C23/00 

FIELD: instrument making.

SUBSTANCE: method includes generation of an image of a virtual object on a flight indicator of a pilot and its system of landing indication, visual control of an aircraft when landing onto a virtual object using its image on the flight indicator of the pilot, maintenance of airplane registered speed close to regular registered speed, and registration of aircraft motion parameters relative to a virtual object. At the same time, using an on-board digital computer, coordinates of aircraft motion are detected in an air system of coordinates by means of integration of components of an aircraft speed vector in an air system of coordinates calculated on the basis of data from measurement of angles of attack, sliding, pitch, course and list by on-board sensors, a regular law of virtual object motion is set in the air system of coordinates at altitude that exceeds the regular altitude of object location, and coordinates of the virtual object are calculated in the air system of coordinates by means of addition of increments of appropriate coordinates of airplane motion relative to their initial values multiplied by the ratio of difference between actual and registered speed of the airplane to the actual speed of the airplane to the coordinates of the virtual object during regular movement. To ensure flight modelling of landing in case there is wind, relative to the object, integrals of appropriate components of the wind speed vector relative to the object are added to coordinates of the virtual object. Produced coordinates of the airplane and the virtual object are used to generate an image of a virtual object and a system of indication of landing on a flight indicator of a pilot.

EFFECT: increased safety and reduced timing of flight training.
