The UK’s Civil Aviation Authority (CAA) has launched an industry-wide project to identify smaller airports within Britain that could benefit from the development of new instrument approach procedures. All industry sectors from airport managers to air traffic controllers to pilots and commercial operators are encouraged to offer suggestions on potential airport recipients.
One of the air traffic management systems least well known to pilots is multilateration, sometimes called MLat, or multilat, or WAM (for wide-area multilateration).
Honeywell’s SmartView Lower Minimums (SVLM) must be able to show precisely where the aircraft is, without the use of additional navigation signals from transmitters on the ground, as well as tell the pilot when a system malfunction makes the lower-minimums approach unsafe. Honeywell uses five monitors to ensure the integrity of the system and the aircraft’s position.
Construction begins today on Runway 6/24 at Trenton Mercer Airport (KTTN), New Jersey, that will significantly restrict its use. The work, to install engineered material arresting systems (Emas) on both ends of the runway, will continue until November 8. Some approach and runway lighting and instrument approach systems will be unavailable and the runway will be closed to aircraft with approach speeds greater than 121 knots. The runway’s usable length will also be shortened by more than 750 feet. Construction work will be under way for approximately 20 hours each day.
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.
As part of continued cost cutting by the U.S. federal government, the FAA has announced plans to begin decommissioning some instrument approach procedures (IAP) to save on maintenance costs of ground-based navaids. The agency said the plan also stems from a near doubling of new IAPs in the past decade thanks to advances in satellite-based approach systems.
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.
Horizon Air has received FAA approval to fly instrument approaches to required navigation performance (RNP) 0.1 standards in its Bombardier Q400s equipped with Universal Avionics UNS-1Ew flight management systems. The UNS-1Ew Waas/SBAS FMS enables Horizon pilots to fly stable 3-D flight paths to touchdown at airports in the Northwest U.S. that have published RNP approaches, but now to lower RNP 0.1 minimums. Compared to traditional but non-RNP approaches, the RNP approaches have been shown to save time and fuel.
Gulfstream Aerospace’s enhanced vision system (EVS) II and head-up display (HUD) II for the G280 are now FAA certified, the company announced late last week. Combined, the systems–which are integrated with the G280’s Rockwell Collins Pro Line Fusion-based PlaneView280 avionics–allow pilots to see terrain, runways, taxiways and possible obstructions in low-visibility conditions.
Chicago Rockford International Airport (KRFD)–65 miles west of Chicago O’Hare International Airport–has released guidelines for aircraft arriving for practice instrument approaches at the nine satellite airports controlled by Rockford approach control. Rockford officials remind pilots that approach control provides practice-approach separation and sequencing only when workload permits it, and then only as far as the final approach fix.
