SYSTEM AND METHOD FOR DISPLAYING VERTICAL REFERENCE ON A ROTORCRAFT SYSTEM

摘要

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.

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.
