Since the introduction of the enhanced ground proximity warning system (EGPWS) in 1996, more than 16,000 airplanes worldwide have been fitted with the Honeywell-manufactured safety device. In that time, the CFIT (controlled flight into terrain) accident rate among aircraft that carry EGPWS has dropped to zero.

Two days of test flying are all that remain before the FAA can put its stamp of approval on T2CAS, the combined TCAS and TAWS product from Phoenix-based ACSS. Pilots from the FAA’s Long Beach, Calif. certification office plan to evaluate the system for the final time in ACSS’ King Air C90 test aircraft later this month.
“One of the myths about the impact of automation on human performance is that as the investment in automation increases, the investment needed in human expertise decreases. In fact, increased automation creates new knowledge and skill requirements.”

Honeywell and ACSS have agreed to let a private arbitrator resolve their ongoing legal dispute over EGPWS patents. As a result, Honeywell has dismissed its lawsuit against ACSS (filed last August in U.S. District Court in Delaware) which had accused the smaller company of infringing patents first applied in the enhanced version of Honeywell’s GPWS.
After wrapping up more than 200 hours of flight testing with Pilatus in the Next Generation PC-12, Honeywell anticipates receiving TSO approval for its Primus Apex avionics system this month.
Flight and navigation technology can help pilots see and avoid threats, simplify cockpit management and know their situation and parameters with precision. The future may advance all of these capabilities, though not always for the original reasons.
Safe Flight Instrument last month announced it has gained approval for a low-airspeed awareness (LAA) display as part of the angle-of-attack (AOA) computer system used in the EFI-890R retrofit cockpit in a Challenger 601-3A. The retrofit avionics system, developed by Universal Avionics of Tucson, Ariz., presents LAA warnings alongside TAWS, TCAS, weather, navigation and other flight information on four 8- by 9-inch displays.
Sandel Avionics last month reported it has shipped its 1,000th ST3400 terrain awareness and warning system (TAWS), a 3-ATI-size unit that includes a TAWS database, processor and color display in a single panel-mount package that
Eurocontrol is offering equipment exemptions until March 31 next year for operators flying to Europe without ACAS II (TCAS with Change 7). A rash of problems related to obtaining necessary STCs and Service Bulletins, equipment non-availability and certification problems has been plaguing operators since before the original January 1 deadline, prompting the extension.
Honeywell is on the verge of gaining FAA certification approval for retrofit versions of its Primus Epic integrated avionics suite. Targeting older medium and heavy business jets, Primus Epic CDS/R (control display system/retrofit) has been developed to transform steam-gauge-driven dinosaurs into state-of-the-art hot rods capable of meeting airspace operating requirements for the next decade or more.
