Abstract
Helmet mounted display apparatus for use in aircraft and rotorcraft includes an first image source for generating images comprising pilotage symbol information, a second image source for sensing and generating images of the exterior scene, and relay optical components that optically superimpose the two images together and subsequently project the superimposed image into the observer's forward field of view.
