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.

GBAS remote satellite measurement unit

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.

Littleton, Colo.-based JetTech received FAA STC approval to install touchscreen GTN 650/750 GPS navcoms in Cessna CitationJets manufactured from 1993 to 1999 (S/Ns 0001 to 0359). The approved STC is for single or dual GTN 650/750 installations and 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 include full support through the installation process.

Indra Navia ILS system

Nav Canada is nearing completion of a nationwide instrument landing system (ILS) replacement program designed to replace legacy systems and provide precision approach capability at new locations. On June 17, the Canadian air navigation service provider (ANSP) announced that it has placed an order with Indra Navia of Norway for the program’s final phase.

After AIN published an article recently about approvals required to fly LPV approaches outside the U.S., a helpful pilot reader offered additional useful information. The story explained, “This requirement [the need for a letter of authorization] flies in the face of the deviation the FAA filed from ICAO requirements that do not require Part 91 operators to obtain approval for any performance based navigation (PBN) procedures.”

May 12, 2014 - 11:00am

The FAA does not require a letter of authorization to fly a localizer performance with vertical guidance (LPV) approach within the U.S. However, guidance for flying in other parts of the world–such as in Europe where the number of LPV approaches is growing–is not nearly as clear and straightforward.
