Method for presenting the drift values of an aircraft
View Patent ↗A method for presenting the current drift values of an aircraft on a display device in which the drift values are presented in a vector presentation. The length of the drift vector above a predefined threshold value is presented in a manner proportional to the current drift velocity, and the length of the drift vector below the threshold value is presented in a manner disproportionate to the current drift velocity. There is a continuous transition between the two ways of presentation at the threshold value.
1. A method for representing current drift values of an aircraft on a display device, the drift values being represented as vectors, the method comprising:
determining, by a processor, whether a current drift velocity of the aircraft is above or below a predetermined threshold value;
displaying a length of a drift vector proportional to the current drift velocity when the current drift velocity is above the predetermined threshold value; and
displaying the length of the drift factor overproportionately to the current drift velocity when the current drift velocity is below the predetermined threshold value,
wherein there is a continuous transition in the display of the length of the drift vector at the predetermined threshold value,
wherein the overproportional relationship between the current drift velocity and the length of the represented drift vector is logarithmic.
2. The method as claimed in claim 1 , wherein a predicted value for the drift value is superimposed on the display of the current drift vector, wherein the predicted value is represented proportional or overproportionately to the current drift velocity depending upon whether the predicted value is above or below the predetermined threshold value.
3. The method as claimed in claim 2 , wherein the display of the drift vector or the display of predicted value is performed by representing only an endpoint of the vector with reference to a fixed start point.
4. The method as claimed in claim 3 , wherein a vector defined by the endpoints of drift vector and predicted value is displayed.
