Technical standard orders for terrain awareness and warning systems (TAWS) have been revised as TSO C151b, which includes a new class-C category intended for voluntary installations on smaller aircraft not covered by the requirements for class-A and -B TAWS. In March 2005 class-A and -B TAWS are required in turbine aircraft with six or more passenger seats, with class-A systems intended for larger Part 91 airplanes and commercial aircraft.
The legal battle over EGPWS patents between Honeywell and competing manufacturers of TAWS avionics has stretched the limits of civil debate as executives on both sides of the imbroglio now find themselves locked in a war of rhetoric aimed at telling why the other side is wrong.
A five-display upgrade for the Falcon 50 has been STC’d, according to Universal Avionics, developer of the retrofit package.
Capital Aviation in Bethany, Okla., has completed installation of Universal Avionics’ EFI-890 EFIS, including elements of the Vision 1 synthetic-vision system, in a Gulfstream III, the installer announced last month. The cockpit retrofit included the addition of four eight- by nine-inch displays, a Universal terrain awareness and warning system and upgrades to the FMS.
• Goodrich accepted terms of a licensing agreement with Honeywell to settle a lawsuit in which Honeywell claimed that Goodrich infringed on EGPWS patents. The deal allows Goodrich to continue selling its own TAWS units while paying licensing fees to Honeywell. But Goodrich won’t keep its TAWS units much longer because the company last month agreed to sell its avionics business to L-3 Communications.
Elliott Aviation has received FAA STCs for installing Universal flat-panel integrated displays (FPIDs), Universal TAWS and Collins AHRS in Citation 550/560s. The Universal FPID STC replaces the standard Citation electromechanical or EFIS ADI and HSI flight instruments with Universal EFI-550 five-inch LCD FPIDs. Two-, three- or five-tube installation options are available.
Although, sadly, the man most responsible for the accomplishment would not be around to see this day, Universal Avionics last month received FAA approval for the company’s EFI-890R retrofit cockpit in a Challenger. A week before the FAA awarded an STC for the Challenger series, on September 12, company founder Hubert Naimer died in Vienna, Austria, of natural causes at age 82.
Universal Avionics of Tucson, Ariz., has been quietly strengthening its foothold in the cockpit retrofit market, branching out with a variety of available upgrades based on the company’s flat-panel display technology.
Universal Avionics plans to announce FAA certification of the first TSO’d WAAS-qualified FMS for installation on Part 23 and 25 aircraft at a press conference today at
2 p.m. The new Universal W series FMS allows operators to use GPS as a primary means of navigation and to fly WAAS/LPV IFR approaches. The W series FMS is certified to TSO C146b, Class Gamma-3, according to Universal Avionics.
Universal Avionics Systems Corp. of Tucson, Ariz., announced that Charles Edmondson, one of the founders of the company along with the late Hubert Naimer, has retired. The two men founded the company in Torrance, Calif., in 1980. As executive vice president, Edmondson had responsibility for Universal Avionics’ worldwide operations. More recently, he served as senior corporate vice president and as a member of the board of directors.
