SYSTEM AND METHOD FOR DISPLAYING VERTICAL REFERENCE ON A ROTORCRAFT SYSTEM
First Claim
Patent Images
1. A method for providing visual vertical guidance during rotorcraft landing, the method comprising:
- displaying a landing point;
displaying a first pole having a first, static, predetermined height at a first predetermined location with respect to the landing point;
displaying a second pole having a second, static, predetermined height at a second predetermined location with respect to the landing point;
obtaining terrain and elevation data;
obtaining rotorcraft position data;
dividing the first pole into equal first pole sections of a predetermined size;
dividing the second pole into equal second pole sections of the predetermined size;
rendering the first pole and the second pole in visually distinguishable pole sections indicative of rotorcraft position above the terrain; and
altering the visually distinguishable pole sections to indicate rotorcraft roll.

Abstract
A method and system for maintaining visual vertical reference on a rotorcraft display during rotorcraft landing is provided. The method generates vertical poles and positions them on the rotorcraft display such that vertical reference as well as roll information may be quickly and easily comprehended by a pilot.

10. A system for providing visual vertical guidance during rotorcraft landing, the system comprising:
-
a first source of terrain and elevation data; a second source of rotorcraft position data; a user input device providing a landing point; a display system; and a processor coupled to the first source, the second source, the user input device, and the display system, the processor configured to; obtain the landing point; create at least two vertical reference poles of a predetermined height; generate symbology on the display graphically representative of a composite image of (i) the terrain and elevation proximate to the landing point, and (ii) the at least two vertical reference poles;
positioned at separate predetermined locations, and rendered in visually distinguishable sections representative of rotorcraft position above the terrain; andalter the visually distinguishable sections of the at least two vertical reference poles to indicate direction and magnitude of rotorcraft roll. - View Dependent Claims (11, 14)

15. A method for providing visual vertical guidance during rotorcraft landing, the method comprising:
-
obtaining terrain data; obtaining a landing point; obtaining rotorcraft position data; displaying a substantially circular line of a predetermined diameter surrounding the landing point; displaying a first pole at a first predetermined location on the circular line; and displaying a second pole at a second predetermined location on the circular line; rendering the first pole and the second pole in visually distinguishable pole sections indicative of rotorcraft position above the terrain. - View Dependent Claims (16, 18, 19, 20)
