Pulling into position for takeoff or passing the final approach fix for landing, especially at a mountain airport, presents many challenges. The accident history of corporate jets indicates an apparent lack of preparation for contingencies, such as engine failure on takeoff, mountain wave turbulence, extreme cold temperature errors in altimeters, technology glitches, changes in IFR clearance and so on.
Terrain awareness and warning system
Honeywell researchers are demonstrating a synthetic-vision system (SVS) that uses terrain and obstacle data taken from the company’s enhanced ground proximity warning system (EGPWS) to paint computer-generated views of the world ahead on aircraft flight displays.
Sandel Avionics last month introduced the SN3500 line of electronic HSI units, featuring compass, map, flight-plan display and RMI, along with traffic, terrain and weather displays. Developed as a replacement for the SN3308, the new product line includes the basic 3-ATI EHSI and supports nav functions, mode-S transponder traffic input and the WX-500 Stormscope. According to Sandel, there are three versions of the SN3500.
Chelton Flight Systems announced completion of the STC for the company’s FlightLogic synthetic-vision EFIS in the Cessna Citation 501.
Watch for the NTSB soon to release recommendations intended to improve the safety of EMS helicopter operations.
Aviation Communication & Surveillance Systems (ACSS), a joint L-3 Communications and Thales company, used last month’s Paris Air Show to introduce technology intended to warn pilots of runway and taxiway incursions.
The FAA last month granted Innovative Solutions & Support an STC for installation of the company’s 10-inch displays in the Pilatus PC-12. Like its previous PC-12 approval for installation of two 15-inch display units, IS&S’s latest STC includes TCAS, TAWS and RVSM compatibility.
Business Jet Technologies, the co-developer of the Quiet Technologies Stage 3 hush kit for the Gulfstream II/IIB, has launched avionics upgrade programs for the aircraft models based on the recent mandates for terrain awareness and warning systems (TAWS) and reduced vertical separation minimums (RVSM) equipment.
A very sore-throated EMS pilot named Mark Graveline, who flies a Bell 206 equipped with the Chelton Flight Systems FlightLogic EFIS for Air Methods of San Antonio, talked about the cockpit system with HAI Convention News at the show yesterday.
Terrain awareness and warning systems (TAWS) designed specifically for helicopters may soon be in hot demand, following the January 25 release of a report by the NTSB calling for the FAA to impose tighter safety guidelines for helicopter emergency medical service flights.
