Abstract
Abstract According to a process for representing information for guiding the flight of an aircraft, the airspace with at least one horizon and the precalculated flight path of the aircraft are three-dimensionally represented by means of animage display device and the surface above the horizon is subdivided into strips of different colours which extend parallel to the horizon. When the point of the precalculated flight path of the aircraft coincides with its shadow, the symbol that represents said precalculated flight path advantageously takes the position of the shadow projected on the ground. The shadow is preferably represented by a transparent design.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
75 words
In a method of representing flight guidance information of an aircraft, wherein a spatial representation of the airspace, comprising at least one horizon and the precalculated flight path of the aircraft, is produced with the aid of an image reproduction device, the improvement wherein the area above the horizon is subdivided into strips of different hue which run parallel to the horizon, and wherein a predetermined set range of pitch angles corresponds to each strip.
Claim 2
Dependent Claim
75 words
In a method of representing flight guidance information of an aircraft, wherein a spatial representation of the airspace, comprising at least one horizon and the precalculated flight path of the aircraft, is produced with the aid of an image reproduction device, the improvement wherein the area above the horizon is subdivided into strips of different hue which run parallel to the horizon, and wherein a predetermined set range of pitch angles corresponds to each strip.
Claim 3
Dependent Claim
16 words
The method according to claim 1, wherein the predetermined set range of pitch angles is 10°.
Claim 4
Dependent Claim
18 words
The method according to claim 1, wherein a warning color is exhibited above a predetermined maximum pitch angle.
Claim 5
Dependent Claim
54 words
The method as claimed in claim 1, wherein numerical indications are displayed in an imaginary extension of the plane of the aircraft in the airspace, the indications being figures inside a frame, wherein respective background of sky or ground is visible in the part of the frame which is not covered by the figures.
Claim 6
Dependent Claim
23 words
The method as claimed in claim 1, wherein a shadow of the precalculated flight path projected on the ground is of transparent design.
Claim 7
Dependent Claim
16 words
The method according to claim 1, wherein the area above the horizon is displayed in blue.
Claim 8
Dependent Claim
16 words
The method according to claim 4, wherein there are two numerical indications of the pitch angle.
Claim 9
Dependent Claim
18 words
The method according to claim 2, wherein a warning color is exhibited above a predetermined maximum pitch angle.
Claim 10
Dependent Claim
77 words
In a method of representing flight guidance information of an aircraft, wherein a spatial representation of the airspace, comprising at least one horizon and the precalculated flight path of the aircraft, is produced with the aid of an image reproduction device, the improvement wherein vertical deviations from a scheduled flight path displayed in the airspace are displayed as colored markers on the upper or lower peripheries respectively of a scheduled route lane encompassing the scheduled flight path.
Claim 11
Dependent Claim
77 words
In a method of representing flight guidance information of an aircraft, wherein a spatial representation of the airspace, comprising at least one horizon and the precalculated flight path of the aircraft, is produced with the aid of an image reproduction device, the improvement wherein vertical deviations from a scheduled flight path displayed in the airspace are displayed as colored markers on the upper or lower peripheries respectively of a scheduled route lane encompassing the scheduled flight path.
Claim 12
Dependent Claim
27 words
The method according to claim 9, wherein the markers are lines which run parallel to the upper or lower perpheries respectively edges of the scheduled route lane.
