Instrument landing system

A recent FAA flight check discovered a previously unknown obstruction beneath the Runway 4 ILS glideslope at New York La Guardia Airport (KLGA), ruling out a full ILS approach to that runway. Aircraft landing on Runway 4 can now use only the localizer approach, which carries minimums nearly 300 feet higher. In poor weather, the only practical option for the area is to operate both LGA and John F. Kennedy (KJFK) airports on a southeast runway configuration, which, in turn, creates significant arrival delays at nearby Teterboro Airport (KTEB).

The FAA is seeking responses to a notice of proposed rulemaking (NPRM) that it believes will significantly improve operational flexibility for operators using an enhanced flight vision system (EFVS). Comments on FAA-2013-0485 are due by September 9.

The captain of an Embraer ERJ-145 has highlighted what he says was a “serious threat to flight safety” caused by the actions of air traffic controllers during an approach to Charlotte Douglas International Airport (KCLT) last January.

According to testimony recently given through NASA’s confidential aviation safety reporting system (ASRS), the flight in low-visibility conditions (reported as one quarter mile) encountered radar altimeter problems that eventually caused the crew to miss their first Category II ILS approach at CLT and head to an alternate.

The FAA issued a recommendation on July 28 to the flight crew of non-U.S. airlines flying into San Francisco International Airport (SFO) to back up a visual arrival by using a GPS approach normally stored in the aircraft’s flight management system (FMS). The onboard approaches can generate a virtual glideslope during visual approaches regardless of the status of ground-based electronics.

The Asiana Airlines Boeing 777-200ER that crashed while landing at San Francisco International Airport (SFO) on Saturday had approached the runway at a speed “significantly below” the 137 knots targeted by the crew, according to preliminary data authorities have extracted from the airplane’s flight data and cockpit voice recorders.

If ever there was a Comeback Kid in avionics, it would have to be the FAA’s wide area augmentation system (Waas). Heralded by the agency in 1994 as the future Swiss Army knife of navigation, Waas was going to bring greater accuracy and enhanced reliability to the sometimes unpredictable GPS and, in so doing, promised a new era where satellites would replace not only the nation’s NDBs and VORs, but also the more than 600 Category 1 ILS installations in the National Airspace System at the time. Development would cost more than $300 million, and take about four years.

Rockwell Collins has won separate contracts from China’s Xiamen Airlines and China Southern Airlines involving several of its avionics systems, including its Multi-Scan Threat Detection Radar and GLU-925 Multi-Mode Receiver (MMR).

Century Flight Systems has ramped up autopilot certification activities and recently received STCs for Century 4000 installations in most Piper Cherokees and Saratogas. The company also received STCs for most Cessna 182s as well as the 421B and 421C twins. Prices for the C4000 start at $19,995.

The Civil Aviation Administration of China (CAAC) has approved both an RNP approach to an ILS and an RNP AR (authorization required) approach for Zhangjiajie Airport (ZDGY) in southeastern China to help increase its capacity. Surrounded by rugged mountainous terrain, the airport sits in the middle of what the country’s Civil Air Navigation Services Organization (Canso) calls “complex airspace that limits operations at peak hours for both inbound and outbound traffic.”

An Air France A340-300 nearly crashed while on approach to Paris Charles de Gaulle Airport (CDG) on March 13 last year because the crew failed to understand the danger cues the aircraft’s flight systems were showing them. The aircraft was already above the recommended altitude for glideslope intercept–with speedbrakes deployed–as it was being vectored for the Runway 8R Cat III ILS at CDG. On low-visibility approaches at CDG, ATC procedures also require aircraft to be slowed to less than 180 knots within 15 miles.
