Head‐up and other Displays

ELECTRONIC Head‐up Display systems have now been under development in the UK since the mid 1950's. All applications to date have been to military aircraft and it is now generally accepted that an electronic HUD is an essential component of the avionic system of virtually all modern strike aircraft. The original development work was prompted by the need for a flexible and comprehensive display for use in the realy types of low‐level strike aircraft, as this mode of operation requires extra data to be displayed and a wider optical field of view than could be provided by the then existing electro‐mechanical gun sights.
