The FAA’s new rules allowing the used of enhanced flight vision systems (EFVS) instead of natural vision to descend below 100 feet above touchdown zone elevation and then land and roll out will likely lead to installation of more head-up displays (HUD) and wearable head-mounted displays in an expanding variety of aircraft types. Avionics manufacturers are ready for the rule change and preparing for the added utility offered by their HUD systems, and some are offering products that can meet the new rules’ requirements for aircraft not equipped with a HUD.
