A “drop-in” replacement for unleaded aviation gasoline is unavailable and alternative fuels would require a “significant” safety assessment, leaving a solution possibly years away, a committee has found.
Northrop Grumman and Quest Aircraft Co. of Sands Point, Idaho, are teaming to explore civil, military and government applications of the Quest Kodiak aircraft integrated with a modular, reconfigurable C4ISR [command, control, communications, computers, intelligence, surveillance and reconnaissance] system.
The FCC is indefinitely suspending LightSquared’s conditional waiver to operate its proposed 4G voice and data network in bands adjacent to those used by GPS, citing concerns that potential interference with GPS units could pose aviation safety risks.
“The commission clearly stated from the outset that harmful interference to GPS would not be permitted,” the FCC says. “Consequently, the commission will not lift the prohibition on LightSquared.”
Gulfstream Aerospace has announced it will expand its used aircraft sales to include full aircraft brokerage services for sellers and buyers.
Jim Ross, vice president, Pre-owned Aircraft Sales, will head the Gulfstream Pre-owned Brokerage group. The group intends to leverage its proprietary worldwide customer and prospect database to present sellers’ aircraft to decision makers.
After a review of the latest round of tests of the GPS interference potential of LightSquared’s proposed wireless network, the National Space-Based Positioning, Navigation and Timing (PNT) Executive Committee has determined that “both LightSquared’s original and modified [plans] would cause harmful interference to many GPS receivers.”

After a 14-year production run, the 250th and last Gulfstream G200 super-midsize business jet rolled out of the Gulfstream Mid-Cabin Completions Center in Dallas on Dec. 20 for customer delivery later this month.
The second round of testing for potential GPS interference from LightSquared’s proposed broadband network shows interference with a “majority” of GPS receivers, the U.S. Departments of Defense and Transportation say.
The agencies released a joint statement late Dec. 14 on the recently completed testing for interference from LightSquared’s proposed operation of high-powered 4G LTE (long term evolution) ground stations in the Mobile Satellite Service band, intended for satellite downlink.
LightSquared is calling for an investigation of the source of possibly leaked data from the recently completed GPS interference tests conducted by the U.S. government that evidently contradict more favorable test results recently promoted by the company.
No matter how you gauge the success of Boeing’s 777, whether in terms of sales, profitability, safety, versatility, longevity or derivatives, few can argue the remarkable impact the twinjet has made on the industry since entering service almost 20 years ago....More
During its nearly 100 years of coverage, Aviation Week & Space Technology has covered many controversial programs. Perhaps none has been as big in terms of sheer value and global reach as the nine-nation, stealthy F-35 fighter project....More
