Upgraded Hawker 800 wins FAA approval
The FAA has awarded a supplemental type certificate to equip the Hawker 800XPR with Honeywell TFE731-50R engines and factory winglets. The work will be done by factory-owned Hawker Beechcraft Services facilities. Customer deliveries were to start in September. “The Hawker 800XPR factory upgrade underscores our commitment to our customers with products that improve performance, lower operating costs and increase resale value of the aircraft we design and build,” said Christi Tannahill, Hawker Beechcraft vice president. “As the first of two Hawker XPR upgrade programs in development, the 800XPR will be joined by the 400XPR that is expected to certify in 2012.” Capable of producing 5,000 pounds of thrust but flat rated to 4,660 pounds, the Hawker 800XPR’s new engines improved performance and, thanks to lower temperatures, increase durability. The engines reduce fuel consumption by 7 percent. The new engines also deliver a number of green advantages, such as lower noise levels and reduced carbon emissions. TEST PILOT ANSWERS from page 41
1. 3, 1 2. True. The left crab indicates that the aircraft is proceeding toward a low-pressure area. Lacking a current altimeter setting, true altitude at such a time becomes less than indicated altitude. This is a variation of Buys Ballot’s Law: “If your back is to the wind, lower pressure is to your left (in the Northern Hemisphere).” 3. The Boeing B–29 Superfortress used to drop the atomic bomb on Hiroshima was the Enola Gay, mother of the bomber’s command pilot, Paul W. Tibbets. 4. It is true on Continental engines, but the number-one cylinder on a Lycoming is the most forward cylinder on the right (with respect to tractor engines, not pusher engines). 5. Nothing. The producers took advantage of a landing-gear malfunction by asking the pilot to delay his landing until a film crew could be put into position. 6. (c) The other items are visual signs indicating the possible presence of a microburst. 7. After returning from his flight from New York to Ireland, Douglas “Wrong Way” Corrigan endorsed a number of products that operated the wrong way. 8. They were technically called Zero Zeros, which represented the last two digits of the year in which they were designed, the 2,600th year of the Nipponese Dynasty (1942).

Students claim human-powered chopper record
The National Aeronautic Association has certified the July 13 record for the University of Maryland’s human-powered helicopter, called Gamera. It lifted off and hovered for 11.4 seconds, setting U.S. records for flight duration, and for flight duration by a female pilot. It was designed and built by graduate and undergraduate students at the University of Maryland’s A. James Clark School of Engineering, and piloted by biology student Judy Wexler, a bicycle enthusiast. The NAA has submitted its findings to the Fédération Aéronautique Internationale (FAI) for evaluation as world records in the same categories. The process may take two to three months. A May flight for liftoff is also under evaluation by FAI. Now, the question is what to do next. Do you set another, better record, or do you just go for it all, represented in this case by the Sikorsky Prize? The American Helicopter Society’s Sikorsky Prize requires a humanpower helicopter to hover for a full minute, and to go as high as three meters, all while remaining in a 10-square-meter area.
