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.

Supersonic business aircraft such as this concept from Spike Aerospace could  be carrying passengers on transoceanic routes within six to eight years.

After Sir Richard Branson launches the first passenger flight of his Virgin Galactic space venture, possibly later this year, he’s indicated that he will turn his attention to developing a supersonic commercial aircraft that can transit from New York to Tokyo (10,800 km; 5,800 nm) in “less than an hour.” He envisions an orbital aircraft, which could reach speeds up to 30,000 kph (16,200 knots).

The Saab Gripen did the first eight development firings of the MBDA Meteor BVRAAM. The European missile house chose the Swedish fighter in preference to the Rafale or the Eurofighter, but the Meteor has since been integrated on all three aircraft.

The integration of new weapons on some combat aircraft has become so expensive that European Defence Agency (EDA) held a workshop to discuss the problem. But Saab (Hall 4 Stand E5 and Chalet C35) has some helpful suggestions, based on its experience with the Gripen. The Swedish fighter served as the development platform for the Iris-T and Meteor air-to-air missiles, and other weapons were successfully added on time and budget.

As Bombardier readies to resume flying its CSeries CS100 test aircraft in “the coming weeks,” it remains confident in Pratt & Whitney’s ability to deliver on its commercial promises that the airplane’s PW1500G geared turbofans will perform at the level and with the reliability both companies expected.

Among the debutantes at this year’s Farnborough Airshow is the Piaggio Aero Avanti EVO, the third generation of this eye-catching twin-turboprop business aircraft. The program was first revealed in May at the EBACE convention in Geneva, but the Avanti EVO’s appearance here is its first public outing at a major airshow.

Boeing Next Generation Bomber

The U.S. Air Force announced that it released a request for proposals (RFP) to industry on July 9 for its new Long Range Strike Bomber (LRS-B) program to develop the next generation heavy bomber. The service said it expects to make a contract award next spring.

Just as in the U.S. there is considerable interest in Europe in developing a solution to the sense-and-avoid problem for unmanned aircraft. A number of different programs are running concurrently under different national, international and industrial consortia, and while several have clocked up significant hours of flight test in surrogate or testbed aircraft, none have as yet flown on board an unmanned platform.

To mark the 70th anniversary of the D-Day landings this year, the RAF painted on a Eurofighter Typhoon the invasion stripes that were used to distinguish allied aircraft in 1944.

Multi-role functionality has been a long time coming for the Eurofighter Typhoon. But the four-nation industrial consortium building the combat jet says the Phase 1 Enhancements (P1E) package that is now entering service represents a “paradigm shift” in capability.

The commander of the UK Royal Air Force (RAF) Typhoon force, Air Cmdr. Gary Waterfall, said the new package allows the RAF to drop 500-pound Paveway IV “smart” bombs “at the moment of our choosing, on targets of our choosing, with a multitude of fuse settings, impact angles and arrivals.”

Rockwell Collins’s flight management system (FMS) and global navigation satellite system (GNSS) receiver successfully enabled the first demonstrations of advanced arrival and departure flight operations for the European Union’s airspace-enhancing project called FilGapp (“filling the gap” in GNSS advanced procedures and operations), the company announced today. FilGapp is intended to create new, more efficient methods of navigating airspace using satellite-based navigation and advanced FMS functions.
