Abstract
The disclosed optoelectronic device is designed to facilitate the piloting of an aircraft under conditions of poor visibility, notably during landing at the stage when the aircraft approaches a runway. It consists of a collimator which displays, in addition to the artificial skyline, miniature aircraft index and attitude bars, a slope scale positioned across and on either side of the artificial skyline, at the position of the selected course chosen by the pilot. This slope scale, depicted in the form of a line of dots spaced out at one slope degree, enables the pilot to be presented simultaneously with information on selected course and slope and enables the determining of pitch attitude with high precision.
Claims5
An optoelectronic device for assistance in the piloting of an aircraft that is provided with a navigation system determining, inter alia, the heading, the pitch attitude and the roll attitude as well as the ground speed vector of the aircraft, and with a collimator for displaying an artificial skyline graduated with a heading scale and surrounded by attitude bars giving a zero roll attitude and slope reference, a reticule identifying the ground speed vector and a fixed reticule formed by a miniature aircraft index identifying the heading and the pitch and roll attitudes of the aircraft with respect to the artificial skyline, wherein said device comprises means for the display, on the collimator, of a slope scale positioned across and on either side of the artificial skyline, at the position of the selected course chosen by the pilot;
- wherein the ground speed vector reticule visually identifies orientation of the ground speed vector in terms of course and slope relative to the slope scale which also identifies the selected course.
