The parallels that Howard Reisman sees between himself and John F. Kennedy Jr. continue to haunt the 57-year-old software designer more than three years after Kennedy’s Piper Saratoga II piston single crashed on a dark and hazy summer night off the coast of Martha’s Vineyard, Mass.
Ground proximity warning system
Thales Avionics has threatened legal reprisals against Honeywell unless the U.S. avionics and engines giant drops a patent-infringement lawsuit against Phoenix-based Aviation Communication & Surveillance Systems (ACSS), a maker of terrain awareness and warning systems (TAWS), TCAS and mode-S transponders, jointly owned by Thales and L-3 Communications.
Goodrich announced during last month’s NBAA Convention the long-anticipated receipt of TSO and STC approvals for its LandMark terrain awareness and warning system (TAWS), which has been selected by Cessna as standard equipment on the new CJ3 and as special equipment options aboard the CJ1 and CJ2.
Makers of terrain awareness and warning systems (TAWS)–mandated safety avionics that the FAA says must be installed in most turbine-powered airplanes by March 2005–have started to fight back against a Honeywell lawsuit alleging infringement of patents relating to the original TAWS: the Phoenix company’s Enhanced Ground Proximity Warning System (EGPWS).
As the market for terrain awareness and warning systems (TAWS) heats up, manufacturers are adjusting prices downward to compete against one another. The latest to announce a price drop was Sandel Avionics of Vista, Calif., which is now selling its class-B ST3400 TAWS/RMI for less than $20,000. The 3-ATI unit is a self-contained TAWS with an integrated RMI.
Garmin has tossed its hat into the terrain awareness and warning system (TAWS) ring, announcing at EAA’s AirVenture in Oshkosh, Wis., last month that a class-B product is in the works and will be offered to buyers of Garmin 500-series avionics “within a year.”
From now until March 29, 2005, business aircraft operators, including those that fly overseas–even if only occasionally–will be required to have a number of additional, and possibly expensive, avionics and other communications, navigation and surveillance (CNS) equipment. This equipment is intended to provide enhanced CNS capabilities for both operators and ATC.
Honeywell last month filed a second patent infringement law-
suit, this time against Phoenix-based Aviation Communications & Surveillance Systems (ACSS), alleging that the company’s forthcoming terrain awareness and warning system (TAWS) uses technology protected under patents filed by Honeywell in 1996 with the introduction of the Enhanced Ground Proximity Warning System (EGPWS).
Honeywell’s patent infringement lawsuit against the makers of terrain awareness and warning systems (TAWS), filed on May 10 in U.S. District Court in Delaware, has stirred a hornet’s nest of criticism by top executives from companies named in the suit.
Honeywell introduced two new collision avoidance and ground proximity warning systems intended for light to medium turbines airplanes. Both the KTA 970 TCAS I and KMH 980 TCAS I/Class B TAWS are TSO’d and capable of tracking up to 60 aircraft and displaying as many as 30 aircraft at ranges up to 40 nm. The KTA 970 lists for $25,752 and the KMH 980 lists for $32,992. The new units are designed to interface with standard EFIS and TCAS displays.
