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.

Later this month, the FAA plans to begin testing a new lighting system at Boston Logan Airport that will warn arriving pilots when their runway is occupied by another aircraft. Called the enhanced final approach runway occupancy signal (eFaros), the new system flashes the existing precision approach path indicator lights to indicate the runway is not safe for landing long before the aircraft is committed to touchdown.

In a ceremony held this morning at Van Nuys (Calif.) Airport, Clay Lacy Aviation owner Clay Lacy donated two “historic” jets to the local aviation maintenance school, North Valley Occupational Center-Aviation (NVOC-Aviation). NVOC-Aviation is operated by the Los Angeles Unified School District adult education program and offers one of the most inexpensive ways for aspiring aircraft mechanics to study for the FAA mechanic certificate with airframe and powerplant ratings, with the 2.5-year full-time program costing just $2,400.

Dr. Lewis “Bernie” Gratzer, the retired vice president of technology at Aviation Partners, passed away on Friday night. Gratzer, already a well respected aerodynamicist, joined Aviation Partners when the company was formed in 1991 to work on a blended winglet for the Gulfstream II. In 1994 he received patent #5,348,253 for his blended winglet design, the lynchpin technology of Aviation Partners’ winglet products. According to Aviation Partners, his winglet design is now flying on more than 6,000 airplanes “and counting.”

The Cessna Caravan, operated by Gogal Air Services, left Snow Lake on Nov.
