First Claim
1. A method of assisting the piloting of an aircraft in which at least one display screen has at least one display zone bounded by a display limit line, the real position of the aircraft being positioned on said at least one display zone relative to a horizontal-vertical frame of reference associated with the screen and a terrestrial horizontal-vertical frame of reference having at least one of its axes displayed by at least one symbol representative of a parameter associated with the dynamic behavior of the aircraft (FPV, . . . ) or of a parameter liable to influence this behavior (FD, . . . ), the at least one symbol having a horizontal component and a vertical component, the method comprising:
- displaying said at least one symbol in said at least one display zone in order to assist the piloting of the aircraft when the real position (FPV) of said at least one symbol lies outside the display limit line, wherein one of the horizontal and vertical components of the at least one symbol, referred to as a “
first”
component, is to be given precedence on display of the at least one symbol in said at least one display zone over a second component of the horizontal and vertical components of the at least one symbol, the method further comprising;
determining the real position (FPV) of said at least one symbol for display relative to said at least one display zone of the at least one display screen;
determining an orthogonal projection (FPV-lock) of the real position of said at least one symbol on an axis corresponding to the first component;
determining the position of said orthogonal projection (FPV-lock) relative to the display limit line of the at least one display zone, and in the event that said orthogonal projection (FPV-lock) is situated outside said display limit line, repositioning said orthogonal projection (FPV-lock) on said display limit line;
determining the position of said at least one symbol on an axis corresponding to the second component passing through the position determined in the preceding step as a function of the value of the second component of said at least one symbol;
determining said position of the at least one symbol relative to the display limit line of said at least one display zone, and in the event that said position of the at least one symbol is situated outside said display limit line, repositioning said position of the at least one symbol on said display limit line; and

Abstract
The invention relates to a method of assisting piloting an aircraft. The method is performed when the real position of a symbol for display lies outside the display limit of the screen. The symbol is representative of a parameter associated with the dynamic behavior of the aircraft (FPV, . . . ) or liable to influence said behavior (FD, . . . ). The symbol possesses two components, and the first component is to be given precedence on display over the second component. In the method, the display of the symbol depends firstly on the orthogonal projection (FPV-lock) of the real position (FPV) of the symbol onto the axis of the first component, and secondly on the position of said projection relative to the display limit of the screen. Such a display makes it possible to give reliable information to the pilot.
