An AD issued last month requires operators of certain Gulfstream IV-SP series to install software and hardware updates to their Honeywell Primus Epic avionics to correct an EFIS display blanking problem. The FAA said it received a report that all four EFIS screens went blank simultaneously for about 74 seconds in flight. Two similar incidents occurred on the ground, according to the agency.

New developments and products in avionics, specifically about aircraft electronics in the cockpit.
Wire strikes–long the bane of low-altitude rotorcraft and agplane operations–could be reduced if a system now undergoing testing on both sides of the Atlantic is able to supplement or even replace marker balls and continuously flashing strobes. It could also aid other low-flying aircraft in avoiding any obstacles in the flight path.
Honeywell has obtained FAA certification of an avionics package that enables Citation 500s to meet the requirements for operating in RVSM airspace, including domestic RVSM scheduled to be implemented next January. Honeywell’s STC covers Citation 500s with serial numbers between 001 and 0274.
West Star Aviation in Grand Junction, Colo., is working with the FAA to amend its Learjet 35/36 RVSM STC to include models with the FC-530 autopilot, FC-200 autopilot and Mark IV wings, FC-200 autopilot and non-Softflite Century III wings or FC-531 autopilot and Century III Softflite wings. The amended STC will allow about 70 to 80 additional 30-series Learjets to meet RVSM equipment requirements.
Business jet operators knew three years ago that they would have to be equipped with approved ELTs by January 1 this year or be grounded until the installation was made. Many operators apparently didn’t take this notice seriously (maybe counting on the FAA to delay compliance, as it has a history of doing) and waited until the last minute to make arrangements for the installation. Or they simply forgot about it.
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.
In the runup to the planned January 20 implementation of reduced vertical separation minimums (RVSM) in the U.S., Canada, South America and Mexico, the FAA has released new guidance documents to assist operators seeking to comply with the requirements of the new operating rules.
Thunder Aviation in Chesterfield, Mo., and Flight Test Associates of Mojave, Calif., are working on an RVSM solution for Falcon 20s equipped with Honeywell Bendix/King KFC 400 autopilots. A group STC is scheduled before the end of the month. Thunder Aviation is also expecting an amendment to its RVSM STC for Falcon 20s equipped with Collins AP105 autopilots that will add similarly equipped Falcon 10s.
The next generation of airborne weather radars won’t just see the storms, they will remember what they have scanned and store that information in a computer database.
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.
