With the FAA now permitting pilots to use enhanced flight vision systems (EFVS) for certain IFR approaches, Elbit Systems (Booth C8938) has responded with several systems designed for the new regulation. At NBAA 2017, Elbit is displaying several EFVS products.
Used on business and passenger jets and recently introduced on helicopters, Elbit’s ClearVision suite represents a “complete” EFVS system that covers the full flight envelope and overcomes extreme weather conditions and low visibility situations during both day and night, the company said.
“ClearVision allows for intuitive ‘head up’ flying, minimizing the dependency on airport and helipad instruments,” according to Elbit. “It is designed to reduce landing minima and provide takeoff credit.”
The ClearVision display fuses conformal flight guidance symbology with a synthetic vision presentation and high-resolution enhanced vision system (EVS) infrared video on a head-up display (HUD) or Skylens visor device.
Elbit's ClearVision HUD presents aircraft data over a transparent glass combiner positioned in front of the pilot. The data is collimated to infinity, enabling the pilot to operate the aircraft using out-the-window views during critical phases of flight.
Its ClearVision EVS is a third-generation design offering high-resolution, cooled infrared imagery for all weather penetration, packed in a single line-replaceable unit.
In December, the FAA issued a final rule outlining new processes that allow pilots flying airplanes equipped with EFVS systems to fly certain IFR approaches all the way to landing “in lieu of natural vision” from the previously allowed elevation of 100 feet above touchdown zone. The rule became effective on March 13.
