Last month AIN reported on the disturbing increase in reports of GPS interference and deliberate jamming and raised the question of continuing GPS reliability if these incidents (attributable to small portable jammers used by truckers to obfuscate their whereabouts) increase in numbers and transmitted power.
The FAA issued an Information for Operators (InFO) bulletin to remind aircraft operators of the potential for erroneous glideslope and/or localizer indications caused by interference from aircraft or equipment moving through ILS critical areas.
GE Aviation and Chile’s LAN Airlines recently conducted the first flight in Latin America using precise performance-based navigation (PBN) procedures from takeoff to landing.
Embraer announced at the Singapore Airshow that it has made substantial interior improvements to the Legacy 600/650 family, which will be available for aircraft produced this year. “Key to this is our effort to reduce cabin sound levels, which set a new benchmark for the Legacy 600 and 650 class of aircraft,” said Embraer Executive Jets president Ernie Edwards.
Rockwell Collins (Booth Q79) has announced that China Eastern Airlines has selected a range of the company’s avionics to equip 50 Airbus A320 aircraft that are on order for delivery later this year. Separately, Hainan Airlines has ordered radars and other equipment for its fleet of 47 new A320s.
The FAA has issued a proposed plan to transition the national airspace system (NAS) to a performance-based navigation system that relies on GPS and “area navigation everywhere and required navigation performance where beneficial,” instead of defining airways, routes and procedures using VORs and other legacy navaids. A minimum operational network of VORs and an “optimized network” of DMEs would be retained, and this drawdown would be complete by Jan. 1, 2020.
“It is the unanimous conclusion of the test findings by the National Space-Based Positioning, Navigation and Timing (PNT) Executive Committee (ExCom) agencies that both LightSquared’s original and modified plans for its proposed mobile network would cause harmful interference to many GPS receivers,” the committee wrote in a letter sent to the National Telecommunications and Information Administration (NTIA) on Friday. The PNT ExCom–composed of nine U.S.
The FAA supplemental type certificate for Garmin’s GTN series touchscreen avionics has been validated by EASA, and the GTN 650 and 750 can now be installed in aircraft registered in Europe.
NBAA helped to pioneer the transition to GPS-based flight decks and procedures, and now the group is taking a leading role to voice the U.S. civil aviation community’s concern about LightSquared’s threat to GPS.
With demonstrated benefits of reducing track miles, mitigating noise and lowering fuel burn and emissions, performance-based navigation (PBN) procedures are being adopted on a worldwide basis. But 15 years after Alaska Airlines flew the first procedures, widespread implementation of PBN is uneven and its benefits largely unrealized.
