METHOD OF FORECASTING FLIGHT VELOCITY VECTOR Russian patent published in 2012 - IPC B64D43/00 G05D1/08 G01C23/00 

FIELD: aircraft engineering.

SUBSTANCE: velocity vector to be indicated is automatically and repeatedly defined to determine its time derivative and calculate controlled velocity vector derivative so that the sum of measured and filtered velocity vector and controlled velocity vector derivative is calculated and magnitude to be displayed is generated. Additionally, control stick deflection from medium position is measured. Said medium position is defined by the method of "sliding average" for time corresponding to response interval. Velocity vector forecast mark position is defined to be summed with previous position. Velocity vector symbol is displayed on the screen.

EFFECT: higher precision of flight path stabilisation in manual aircraft control.
