The FAA has released a notice of proposed rulemaking (NPRM) that would allow many more operators to continue flying below decision altitude/decision height or minimum descent altitude (DA/DH or MDA) during IMC when equipped with enhanced flight vision systems (EFVS). Such systems generally use infrared sensors to deliver real-time images of the external view to cockpit displays, and the new rules would not apply to synthetic vision systems. Millimeter-wave radar could also be used for future EFVS operations.
Synthetic vision system
Garmin’s new GTS 825 TAS (traffic advisory system) and GTS 855 Tcas I (traffic alert and collision avoidance system) had already received FAA technical standard order approval when they were introduced in March. Garmin is now working on approved model list supplemental type certificates for the GTS 825 and 855.
Aircraft synthetic-vision systems (SVS), when combined with GPS, gyros, accelerometers and terrain and obstacle databases, provide pilots with a colorful, animated depiction of the world outside the cockpit, matching what they would see looking through the windshield on a clear day. But to really see what is outside in dark or low-visibility conditions, you need an infrared (IR) camera. When you add forward-looking IR to SVS, you get a heat-referenced, real-world view along with a 3-D, database-derived and geo-referenced virtual view. Together they are called enhanced or combined SVS.
The Bombardier Enhanced Vision System in the Challenger 605 received EASA certification last week. This system, which is already certified by Transport Canada and the FAA, consists of a head-up display and a forward-looking infrared camera, increasing situational awareness by providing an overlay image of the outside environment–including terrain, runway, other aircraft and animals–on the HUD, as well as on the copilot’s multifunction display. This capability further increases safety during taxiing, takeoff and approach in low-visibility conditions, Bombardier said.
Bombardier is offering an avionics block upgrade for its Challenger 300 in response to interest by operators in the Pro Line 21 Advanced system that comes standard in the new Challenger 350, the company announced here yesterday. Bombardier plans to introduce the Rockwell Collins Pro Line 21 retrofit as service bulletins during this year’s third quarter.
Bombardier’s new Challenger 350 will feature an upgraded flight deck based on the Rockwell Collins Pro Line 21 suite, but marketed by Bombardier as the Pro Line 21 Advanced. The Advanced version brings new capabilities to Pro Line 21 and will also be available as a retrofit on Challenger 300s.
Rockwell Collins received the top honor–a gold award in the safety category–from the Edison Awards in recognition of the company’s development of synthetic vision on a head-up display (HUD). The awards program is conducted by Edison Universe, which fosters future innovators. The awards were named after prolific inventor Thomas Edison.
Honeywell already delivers synthetic vision for business aircraft under the brand name SmartView, a system that uses the terrain database of the company’s renowned Enhanced Ground Proximity Warning System (EGPWS), merged with head-up display (HUD) symbology. It then presents the SVS graphics on an aircraft’s primary flight displays (PFD).
Operators lacking approval for precision area-nav (PRnav) operations are finding access to European airports increasingly limited, and Universal Avionics is here at EBACE to emphasize that its satellite-based augmentation system (Sbas) flight management systems (FMS) ensure compliance with the PRnav requirements set out in JAA TGL10. Area nav allows shorter, more direct routes and more precise navigational accuracy in terminal and approach airspace.
The Astronics Max-Viz-1500 enhanced vision system is now available as a factory option for new Bell 429s, as well as for retrofit installations in the light twin helicopter. According to the company, the system permits pilots to see farther than the unaided human eye while offering an added degree of safety and situational awareness in conditions with obscured vision. Retrofit installations will be done at the Bell Helicopter service facility in Piney Flats, Tenn.
