As more aircraft equip with ADS-B out capability, which broadcasts position, velocity, altitude and other information in unencrypted formats on easily received frequencies, business aircraft operators are concerned about whether they can continue blocking their aircraft from display on flight-tracking websites.

As more aircraft equip with ADS-B OUT–which broadcasts position, velocity, altitude and other information in unencrypted formats on easily received frequencies–business aircraft operators are concerned about whether they can continue blocking their aircraft from display on flight-tracking websites. While the FAA offers a way for operators to request blocking of particular aircraft from FAA radar data feeds, there currently is no physical means to block reception of mode-S transponder or ADS-B signals by a simple receiver.

As of July 24, there are 3,430 wide-area augmentation system (Waas) localizer performance with vertical guidance (LPV) approach procedures serving 1,690 U.S. airports. There are also 555 localizer performance (LP) approach procedures in the U.S. serving 404 airports.

The list of FAA GPS procedures using Waas, known by ICAO as space-based augmentation system (SBAS) procedures, continues to grow steadily. These include ILS-equivalent localizer precision with vertical guidance (LPV) approaches, providing centerline and glideslope guidance down to 200 feet at more than 800 Part 139 runways in the NAS, plus another 2,600 at various heights above 200 feet at other NAS Part 139 and non-Part 139 runways. At most of the non-Part 139 runways, of course, there’s no ILS, and probably never will be. SBAS is filling that need.

Rockwell Collins is demonstrating a host of new technology solutions at Farnborough 2014, from its MultiScan weather radar to NextGen communications and navigation systems.

The NTSB says the probable cause of a Beechjet 400 overrun accident in September 2012 at Macon, Ga., was the pilot’s failure to maintain proper airspeed on final approach. Two of the three people on board received minor injuries. The aircraft touched down on a wet runway “at a speed 15 to 19 knots above the calculated Vref speed (based on radar data) of 108 knots with inadequate runway remaining to stop,” the final report said.

The Dutch government’s safety board wants to publicize the existence of false glideslope indications that could cause the aircraft, when coupled to the autopilot, to pitch up rather than down. The insights were gathered during an investigation into a pitch-up incident on a Boeing 737 in which the incident “digressed” until the aircraft’s stick shaker activated.

The board wants pilots to understand the dangerous information these false glideslope signals can send to an aircraft’s autopilot that might cause the system to operate in a manner opposite to what the cockpit crew expects.

Jettech gained FAA STC approval to install the touchscreen Garmin GTN 650/750 GPS/navcom (single or dual) in Cessna 525 CitationJets manufactured from 1993 to 1999 (S/Ns 0001-0359). The STC includes Waas approvals and certifies the aircraft for fully autopilot-coupled GPS-LPV approaches. Jettech is offering the STC’d data package through authorized Garmin dealers and will provide full support through the installation process.

As of June 26 this year, there were 3,423 wide-area augmentation system (Waas) localizer performance with vertical guidance (LPV) approach procedures serving 1,686 U.S. airports. There are also 552 localizer performance (LP) approach procedures in the U.S. serving 402 airports. A complete list of all LPVs and LP approaches is published on the FAA website.

Sydney Airport has placed into operation a ground-based augmentation system (GBAS) supporting satellite-based precision approaches and landings. The airport is the first in Australia to offer a GBAS landing system, Airservices Australia said.
