Takeoff

November 11, 2013 - 2:18pm

Both the December 2012 crash of a Dornier Do-228 on takeoff from the Nepalese capital Kathmandu and the recent crash of an Embraer EMB-120 Brasilia at Lagos in Nigeria have called attention to the need to train pilots in the importance of both attaining and maintaining V2 (takeoff safety speed) before liftoff from the runway. In both accidents, the aircraft stalled and crashed shortly after liftoff.

Nigeria’s Accident Investigation Bureau said Friday that an initial review of the cockpit voice recorder of the Embraer EMB-120 Brasilia that crashed on takeoff October 3 at Lagos confirmed an automated cockpit voice warning alerting the crew to a possible problem before liftoff. The system called out “takeoff flaps, auto-feather,” indicating that one engine might not have been producing takeoff power. At this time it is unclear whether the warnings were made before the aircraft reached V1 rotation speed.

The FAA published the new version of its Notices to Airmen (Notam) guide–JO 7930.2N–on September 25 to bring airport operators up to ICAO standards. For example, Notams must now include key words or phrases to make them easier to identify and sort. New terms might include {{BEGIN SMALL CAPS}} RWY, TWY, APRON, AD, OBST, NAV, COM, SVC, AIRSPACE, ODF, SID and STAR{{END SMALL CAPS}} among others.

The Australian Transport Safety Bureau (ATSB) released a training video highlighting some near catastrophes that occurred after experienced pilots incorrectly entered takeoff data in the flight management computer aboard large airline aircraft, including a Boeing 747 and 767 and an Airbus A340.

Terrafugia, the developer of the Transition roadable airplane, says it is designing a hybrid electric/fossil-fuel-powered flying car in the form of a tiltrotor. The TF-X would use electric drive on the ground and for power assist on takeoff. After reaching cruise, the twin tiltrotor pods would fold their propellers flat while a rear-mounted engine-driven shrouded fan would provide propulsion.

The Australian Transport Safety Bureau (ATSB) recently identified 100 safety risks across its aviation, marine and rail areas of responsibility, 36 of which relate to transport-category aviation. The ATSB report covers the period July 2009 through June 2012. Most risks were operationally focused within the aircraft itself, with a much smaller percentage related to ATC.

Air transport risks in 2011and 2012 also outweighed those identified as related to general aviation by three to one. Only five investigations, however, were categorized as complex (serious).

The U.S. Defense Advanced Research Projects Agency (Darpa) is soliciting proposals from industry for a vertical takeoff and landing experimental aircraft (VTOL X-plane) that would demonstrate “radical” improvements over the current state of VTOL flight. In late February, Darpa issued a broad agency announcement seeking proposals by May 1.

On Monday at Heli-Expo, AgustaWestland revealed that it has been secretly flying an all-electric vertical takeoff and landing demonstration aircraft powered by twin-electric, direct-drive tiltrotors. The “Project Zero” tiltrotor was designed and built in six months by the company’s advanced concepts group and has been flying since 2011. It features elevons for pitch and roll control and in forward flight, a V-tail for longitudinal stability, and a lifting body design with two integrated tiltrotors than can be tilted through 90 degrees.

An “improperly crimped” fueldraulics line is the probable cause of a fuel leak that led the U.S. military to suspend flight operations of the F-35B short takeoff/vertical landing (Stovl) variant of the Joint Strike Fighter, which was grounded on January 18.

Flight operations of the F-35B short takeoff/vertical landing (Stovl) variant of the Joint Strike Fighter remained suspended this week as U.S. military and contractor engineering teams investigated the cause of an engine fueldraulic line failure in a test aircraft at Eglin Air Force Base, Fla. The fueldraulic line is part of the fuel-based hydraulic system that controls the actuators of the F-35B’s vectoring exhaust system. The grounding did not affect the F-35A and C models, respectively, the conventional takeoff and carrier variants.
