| 摘要 |
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. |

1. A method of assisting piloting 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, at least one symbol representative of a parameter associated with the dynamic behavior of the aircraft (FPV, . . . ) or liable to influence this behavior (FD, . . . ) having a horizontal component and a vertical component, the method comprising a step of 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, the method being characterized in that one of the components, referred to as a “first” component, is to be given precedence on display over the second component, and the method comprises the following steps:
determining the real position (FPV) of said at least one symbol for display relative to said at least one display zone; determining the orthogonal projection (FPV-lock) of the real position of said at least one symbol on the axis of the first component; determining the position of said projection (FPV-lock) relative to the display limit line of said at least one display zone, and in the event that said projection (FPV-lock) is situated outside said display limit line, repositioning said projection on said display limit line; determining the position of said at least one symbol on the axis of 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 relative to the display limit line of said at least one display zone, and in the event that said position is situated outside said display limit line, repositioning said position on said display limit line; and displaying said at least one symbol in the display position as determined in this way in the preceding step. |
