Professional Pilot, May 2017

after the certification of the Honeywell EASy II flightdeck and a series of EFVS programs on the Falcon 7X Falcon 900 and 2000 aircraft However the flightpath to zero zero requires both technology and agreed upon standards that incorporate the common sense redundancy of a dual HUD cockpit with integrated sensors and SVS So in 2015 Dassault announced that it was moving ahead with dual HUDs coupled with EFVS and CVS for the new 5X and 8X aircraft The company has the goal of providing integrated EVO in these aircraft to insure the safety of both flightcrew and passengers over undulating terrain in all instrument conditions These CVS innovations serve as a platform for future programs so customers will have global all weather capability posing key economic and competitive advantages for Dassault What FalconEye is and what it does Dubbed the FalconEye this combined EFVS and SVS display on dual HUDs enables both the pilot and copilot to taxi depart fly to and land at a destination with a continuous visual display of the environment The SVS elements enable the crew to always have terrain references and obstacles displayed Dassaults provisions for the CVS display utilize the full field of view of the dual HUDs using SVS as a framework 82 PROFESSIONAL PILOT May 2017 for the EFVS so pilots can see and identify the visual references needed to continue the approach in low visibility The CVS components are based on Elbit Systems multispectral EVS and wide field of view HUD and the CVS software specifications were defined by Dassaults engineering team In many cases when flying using EFVS alone pilots typically only see the lights or a limited part of the runway in the center of the HUD with an infrared IR sensor even though the video output is available for the complete field of view of the HUD The technical reason is the limitation of an IR EFVS sensor to penetrate dense fog or clouds at long ranges FalconEye is designed to improve runway light detection coming from both incandescent bulbs and LEDs using the multispectral EVS It provides a continuous blended view of the terrain by incorporating SVS as well as the real time visual references provided by the EFVS sensors The practicality of integrating EFVS and SVS into a single flight display has been debated for years mostly because the technology just didnt exist This is because the blending of different videos in the cockpit whether for a HUD or a head down display was limited by the intense requirements of graphic rendering technology The next issue was how to add and thoughtfully display standard flight instrument symbology along with the combined imagery Dassault Aviation Head of Navigation and Flight Guidance Systems Alain Boucher is among the OEM leaders of the now famous RTCA Special Committee 213 Boucher along with Olivier Baudson Arnoud Turpin pioneering test pilot Philippe Rebourg and others have created a new flightdeck standard Operating the FalconEye CVS Operation of the FalconEye CVS begins with the selection of the combined vision mode with the CVS ON indication shown on the HUD in conjunction with other flight mode information The CVS symbol is located on the lower left corner of the HUD to verify that you are operating in CVS mode The image displayed on the HUD depending upon altitude and approach configuration will display SVS terrain above the horizon line and during the approach around the EFVS imagery in the middle of the HUD During normal cruise flight the CVS displays the terrain above the HUD horizon line using SVS with fully integrated images from the EFVS sensors that show the airport and terrain below the horizon During the instrument approach segment both pilots will see a more complete story with SVS and EFVS features fully blended but with SVS data surrounding the EFVS image Heres what dual FalconEye CVS HUDs buy for low viz flight ops Dassault FalconEye dual HUD installations provide the operator a flightdeck design that unifies the displays and guidance for both the PIC and copilot The 2 front seats in the cockpit see exactly the same information Debates have raged in the man The FalconEye CVS image on approach The pilot can see terrain shown above the horizon line symbol and an EFVS image overlay with the actual runway
