On the morning of June 18, 1994, a Learjet 25D carrying 10 passengers and two pilots crashed less than a mile from the threshold of Runway 1R on approach to Dulles International Airport.
Europe’s Joint Aviation Authorities (JAA) want to require pilots to respond to resolution advisories (RAs) from airborne collision avoidance systems (ACAS) in all circumstances. On March 1, the regulator issued a notice of proposed amendment (NPA) for JAR-OPS 1.398 rules covering ACAS operations.
The FAA has withdrawn its decade-old proposal to rescind its requirement for Mode-S transponders and adopted a new rule that will end the hundreds of Mode-S installation exemptions currently in effect. Beginning March 1, 2007, Part 121 and 135 operators will no longer be exempted to fly without a Mode-S transponder.
As a result of the Era Aviation Sikorsky S-76++ crash, the NTSB asked the FAA to require terrain awareness and warning systems (TAWS) on all U.S.-registered turbine helicopters that are certified to carry at least six passengers.
FAA Information for Operators 06005 (www.faa.gov/other_visit/aviation_industry/airline_operators/airline_safety/info) released last month alerts operators of aircraft equipped with TCAS and other collision or advisory devices of the potential for traffic advisories or other spurious signals caused by active transponders aboard
Safety information about TCAS equipment and its use is now available in the form of a new FAA Safety Bulletin (www.faa.gov/and/and500/500/docs/TCAS_SAFETY_BUL
The FAA might revive TCAS III. The system, which would add lateral resolution advisories (RA) to the current TCAS II’s vertical commands, was proposed many years ago but dropped after technical investigations showed that it would have been extremely difficult to develop and implement.
The statistics tell the story. Over the last four years, there have been 1,475 runway-incursion incidents at controlled airports in the U.S., an average of one a day. Data from other countries are not readily available, but experts say incursions are on the rise worldwide. While the Federal Aviation Administration has focused primarily on pilot education initiatives to warn of the dangers of incursions, avionics makers have other ideas.
The European Aviation Safety Agency and the Direction Générale de l’Aviation Civile of France have issued approvals for limited use of Honeywell’s runway awareness and advisory system (RAAS) in Europe. The EASA STC covers RAAS installation on the Learjet 31, 35, 36, 55 and 60, while the French authority approved the system for the Boeing 777.
Aviation Communication & Surveillance Systems (ACSS), an L-3 Communications & Thales company, is at Dubai 2005 (Stand E609) featuring its new SafeRoute software which provides flight and ground separation functions residing on a common computing platform.
