Abstract

A flight path display apparatus provided in a cockpit of an aircraft has a head-up display unit. An image combining panel of the head-up display unit displays a flight path image projected from projecting system which is superimposed on the outside view. Computing system for calculating the image to be projected to the image combining panel calculates a display position of the target flight path based on data from storage system in which predetermined flight paths are stored and from aircraft flight data measuring system for measuring the position and attitude of the aircraft. When the display position of the target flight path is outside a display area of the image combining panel, a target mark indicative of a direction toward the flight path from the center of the display area blinks on the image combining panel. With the above construction, a flight path display apparatus which allows a pilot to keep sight on a target flight path is realized.

Claims3

Dependent claims

A flight path display apparatus comprises:

storage means for storing flight path data of predetermined flight paths;
aircraft flight data measuring means for measuring a position and attitude of an aircraft;
computing means for calculating a display position of a target flight path based on the predetermined flight path data and aircraft flight data;
and
head-up display means having projecting means for projecting the target flight path, and an image combining panel, which is disposed in front of a pilot head and for displaying the projected target flight path image by superimposing on the outside view,
wherein said projecting means is operable to project a target mark, indicative of a direction toward the target flight path from the center of a display area of the image combining panel as provided by said computing means, and
wherein said projecting means is operable to blink said target mark at a peripheral edge portion of the image combining panel when the displayed position of the target flight path image is outside of the display area of the image combining panel.
