Situational awareness is fundamental to safe flight. Cockpit instruments can provide precise indications of an airplane’s position and trajectory, but once the world outside grows too dark, cloudy or foggy to see, pilots must rely on the safety margins built into IFR procedures to maintain safe separation from the ground.
In the world’s first major commitment to head-up display and enhanced vision technology by a civil operator, Federal Express announced late last year that it would equip its whole widebody fleet with the new equipment. The HUDs, to be supplied by Honeywell, will incorporate enhanced vision systems built by Kollsman. These two companies provide the HUD/EVS combinations currently being offered by Gulfstream in its G350, G450 and G550.
Scientists and engineers at NASA’s Langley, Va., Research Center are evaluating the integration of a number of separate systems and techniques which, when combined, could achieve significant safety improvements in the approach and landing phase.
An international technical consortium has completed trials on a new head-up display (HUD) that allows helicopter pilots to view the display through night-vision goggles (NVGs) and allows “virtually unlimited” head movement.
New head-up display (HUD) technologies based on liquid-crystal display (LCD) scanning techniques promise to clear the way for smaller, lighter and more reliable hardware that will be capable of providing brighter images and new capabilities, according to manufacturers.
Transport Canada has certified the SureSight I-series infrared (IR) enhanced-vision system (EVS) sensor developed by CMC Electronics, marking one of the last steps before certification and production approval of the complete EVS for the Bombardier Global Express XRS.
Canadian authorities have approved the installation of a Max-Viz EVS-1000 enhanced vision system (EVS) aboard a Global Express. The U.S.-registered jet received the upgrade at ABC Completions in Montreal and gained Canadian approval in late December. An STC from the FAA covering the installation was expected by the end of last month.
In a landmark decision, the FAA has adopted a final rule allowing the use of HUD-based enhanced vision systems (EVS) for descent below published instrument approach minimums.
Certification of the infrared enhanced vision system (EVS) for the Bombardier Global Express XRS–said to be “imminent” at press time–will close an important technology gap between Gulfstream and Bombardier, head-to-head competitors in the ultra-long-range business jet market.
The FAA issued draft Advisory Circular 25-11-1X clarifying electronic cockpit display design rules. First issued in 1987, the revised circular adds information on Class III electronic flight bags, enhanced and synthetic vision systems and electronic standby and head-up displays.
