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.

MBDA Meteor BVRAAM fired from Saab Gripen

Saab has completed integration of the MBDA Meteor BVRAAM on the Gripen. Next year the Swedish air force fighter will be the first to go operational with the new missile, according to Saab. The Dassault Rafale and Eurofighter Typhoon will also carry the Meteor. The Gripen previously conducted the first eight developmental test firings of the ramjet-boosted missile.

A preliminary report into a February 20 elevator disconnect incident on a Virgin Australia ATR 72 showed that maintenance technicians at Sydney Airport initially misdiagnosed the extent of the damage that occurred during that February arrival. The twin turboprop was later cleared to re-enter service and flew 13 more trips before severe damage to the tail was discovered in the area where the horizontal and vertical stabilizers were joined.

Sikorsky and Lord have completed the flight demonstration of a hub-mounted vibration suppressor (HMVS) intended to address crew fatigue and reduced equipment reliability caused by helicopter vibration. Eventually, the HMVS could be part of a larger system integrated into all Sikorsky helicopters.

Bombardier Aerospace announced on June 12 that the Challenger 350 received Transport Canada approval, with FAA certification expected “shortly.” An upgrade of the Challenger 300, the 350 has a new wing with canted winglets, a higher mtow of 40,600 pounds and greater fuel capacity for an NBAA IFR range of 3,200 nm versus its predecessor’s 3,065nm.

The sight of a building badly dented by the right wingtip of an Airbus A380 as the aircraft taxied at Le Bourget Airport ahead of the 2011 Paris Air Show emphasized the challenge posed by ground obstacles to pilots navigating around unfamiliar airports. Honeywell Aerospace seeks to address the problem through an innovative adaptation of its enhanced ground proximity warning system (EGPWS). The new Passive Wingtip Protection System (PWPS), which has based on an upgrade to the EGPWS software, is now under development at the group’s facility in Redmond, Wash.

It is way too soon to speculate about what might have caused the Gulfstream IV runway excursion crash at Hanscom Field in Bedford, Mass. on May 31, but the NTSB preliminary report’s focus on the gust lock system raises some questions.

In a move that could help pave the way for low-boom supersonic flight over land, NASA aeronautics researchers are presenting their work on how people on the ground perceive low sonic booms this week in Atlanta at an annual event held by the American Institute of Aeronautics and Astronautics. “Lessening sonic booms is the most significant hurdle to [civil] supersonic flight,” said Peter Coen, head of the high-speed project in NASA’s aeronautics research mission directorate at the agency’s headquarters in Washington, D.C.

The NTSB’s preliminary report into the crash of a Gulfstream IV during takeoff roll at Bedford Hanscom Field near Boston on May 31 revealed a number of inconsistencies. On June 13, investigators reported that while the flap handle on the jet was set to the “flaps 10” position, the flight data recorder indicated the flaps were set to the “flaps 20” position.
