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.

Method of assisting piloting an aircraft by adapting the display of symbols

The invention relates to a method for adjustment of a harmonization compensation applied to alleviate a discrepancy of conformity between a video image transmitted by a video transducer () and projected by a head-up display device (), of an aircraft, and an external scene ahead of the aircraft. At least one equipment item of the aircraft&#x2014;preferably the said HUD device&#x2014;equipped with at least one control element accessible in the cockpit, is programmed to be able to function according to a nominal mode and according to a maintenance mode, in which at least one of its control elements, known as a redirected control element, is used to define the applied harmonization compensation. An operator activates the maintenance mode and starts an adjustment operation, in which he modifies in real time the applied harmonization compensation, by manipulating at least one redirected control element, until the video image is matched with the external scene.

Method of regulating a harmonization compensation between video sensor and head up display device, and corresponding devices

A crossed monitoring device for a head-up display that can be used for displaying a representation of at least one first datum. The device includes a mechanism generating at least one first image from the at least one first datum, a mechanism receiving from the at least one second display at least one second image generated from at least one second datum, and a mechanism selecting one of the first and at least one second image. The device can further include a mechanism modifying images according to characteristics of the displays. Each display can modify the images to be displayed according to its characteristics, and each display can modify the images according to the characteristics of each display.

Crossed monitoring device for head-up displays

A set of equipment items for an aircraft including a video transducer and at least two head-up display devices, wherein the video transducer and/or each HUD device is/are capable of defining the image to be projected by the HUD device on the basis of the display field of the HUD device and of one or more HUD/transducer errors, each HUD/transducer error being defined as being the difference between the HUD error of the corresponding HUD support around a direction and the transducer error around this same direction, the HUD error of an HUD support around a direction being the angular difference around this direction between the line of sight of the HUD support and a measuring reference line, and the transducer error around a direction being the angular difference around this direction between the line of sight of the transducer support and a measuring reference line.
