An integrated vertical situation display (IVSD) for an aircraft, and method of displaying vertical situation information, are disclosed herein. The IVSD includes an electronic display for displaying the vertical situation of the aircraft, input interfaces for receiving vertical profile information signals, and a processing circuit for reading the information signals and generating display signals applied to the display therefrom. The display has a vertical profile view area to display the vertical situation in front of, above, and below the aircraft. The information sources may include a flight management system, traffic alert and collision avoidance system (TCAS) and a ground proximity warning system. Vertical situations are displayed by visual indicia representing, for example, aircraft position, path angle, flight path, waypoints, TCAS targets, altitude preselect, decision height, runway, ground contour, and vertical speed. The integrated display minimizes the cognitive workload of the operator in assessing the total vertical situation.
The indicator (1A) according to the invention comprises means (13) for determining first and second target values respectively of a variable and of its derivative with respect to time, and display means (5, 6, 7) which depict on a display screen (7) a means of indication (14) of the first target value, which is arranged in such a way as to indicate this first target value on a graduated scale (8), and a means of indication (16B) of the second target value which is associated at least with an indicator element (11) indicating said derivative so that, when the latter points toward said means of indication (16B), said variable of the aircraft becomes equal to and remains equal to said first target value and said derivative is equal to said second target value.
A flight information display for the flight deck of an aircraft showing a pictorial side view of the flight path or the area directly in front of the aircraft area having a selected distance of at least 0.5 nautical miles, comprising (a) a pictorial representation to scale of the profile of the highest elevations of a swath of terrain along said path or area, (b) an icon positioned on the left or right side of the display representing the aircraft, the altitude of which is to scale with the height of the terrain, and (c) an altitude reference scale; wherein the width of the swath is at least 0.1 nautical miles and no greater than the distance of the minimum accuracy of the means for determining the aircraft's location.
A current path display indicator for a display device of a vehicle. The current path display indicator includes a flight path indicator (FPI) and a visual cue associated with the FPI to indicate relative direction from the vehicle's current path to a desired path. The visual cue may be embodied in possibly a number of different ways. For example, it may be embodied as an arrow extending from a circular portion of the FPI; a highlighted segment superimposed on the circular portion of the FPI; a triangle extending from the circular portion; or, a pie-shaped marker contained within the circular portion.
Methods and apparatus are provided for generating an integrated vertical situation display. The method comprises generating a profile view frame, producing a first profile view of a first track of the vehicle in the profile view frame beginning at about a current position of the vehicle and ending at about a predetermined location, and extending a second profile view of a second track of the vehicle from about the predetermined location. The apparatus comprises a display configured to display a profile view frame and a specially configured processor coupled to the display. The processor is configured to produce a first profile view relating to a first track of the vehicle beginning at about a current position of the vehicle and ending at a predetermined location, and generate a second profile view relating to a second track of the vehicle extending from about the predetermined location.
A vertical deviation indicator and predictor includes a vertical deviation scale having a plurality of vertically spaced markers, one of the markers indicating the vehicle's present vertical position. Current vertical flight path segment symbols are selectively superimposable over the vertical deviation scale in accordance with the vehicle's current vertical flight path segment. Next vertical flight path segment symbols are selectively superimposable over the vertical deviation scale in accordance with the vehicle's next vertical flight path segment, the position thereof being determined by backward extrapolation of the next vertical flight path segment. Thus, the type and position of the current and next vertical flight path segment symbols on the vertical deviation scale provide situational awareness of the present vertical flight path deviation and an indication of an efficient and timely manner for intercepting the desired flight path.
