The ForeFlight team has released a major update to the ForeFlight Mobile iPad app–Version 5–featuring a new hazard advisor with terrain and obstacle awareness, new runway advisor features such as a traffic pattern advisor, runway winds and automatic display of taxi diagrams. The terrain map and Hazard Advisor work only on newer iPads (iPad mini, 2 and later) and iPhones (4 and later).
China’s under-development J-20 combat aircraft recently demonstrated its missile-launch mechanism, which the Chinese media tout as a simple but “more efficient” design than that of the American F-22.
A proposed Learjet 60 airworthiness directive
Researchers at the German Aerospace Center (DLR) in Göttingen may have discovered a way to make helicopters more maneuverable, by reducing the dynamic load on the rotor head control rods.
During rapid forward flight or maneuvering, airflow stalls on the main rotor blade as it retreats (moves backwards), giving rise to a “dynamic stall” and subjecting the rotor head control rods to formidable dynamic loads.
Major fighter manufacturers displayed their wares this week at the 2013 Langkawi International Maritime and Aerospace (LIMA) exhibition in Malaysia in anticipation of that country’s pending requirement for new fighters. Five aircraft considered contenders for the program–the Eurofighter Typhoon, Saab JAS-39 Gripen, Dassault Rafale, Boeing F/A-18F and Sukhoi Su-30MKM–participated in the aerial display.
As experts struggle to identify why the crew of Air France 447 lost control of their A330 over the South Atlantic Ocean nearly four years ago, the industry is also still struggling to develop the precision data needed to accurately reproduce a stall in a Level D simulator. The lack of accurate stall data limits entry and recovery practice because the computers running the simulators have no idea how the aircraft will actually perform.
Faced with growing costs in the Lockheed Martin F-35 program, Denmark is reviewing its options for a new fighter and has invited Boeing (F/A-18 Super Hornet), Eurofighter (Typhoon) and Saab (Gripen E) to submit information for alternatives. A decision is due in 2015. Dassault (Rafale) may have been approached, but at the time of writing appeared unlikely to respond. The company has a history of not bidding on programs that it calculates have little chance of success.
MBDA has confirmed that production rounds of the Meteor long-range air-to-air missile are scheduled for delivery before year-end. However, MBDA managing director Steve Wadey would not disclose which air force will be the first to get the new missile, which MBDA UK claims represents a “step change in the air-to-air world.” AIN reported last year that French Rafale and Swedish Gripen fighters would be flying operational Meteors ahead of the four Eurofighter nations.
Gardner Aviation Services is offering a general aviation fixed-wing and rotorcraft product support catalog that features avionics, instruments and pilot supplies, including the latest in digital displays, communications and ADS-B technologies. The new catalog serves as a buyer’s guide for selecting equipment designed for both fixed- and rotary-wing aircraft. Product photos and descriptions identify hundreds of items and their function.
The FAA is adopting an airworthiness directive (AD) for the Cessna 750 Citation X prompted by reports of loss of displayed airspeed.
