NATIONAL BUSINESS AVIATION ASSOCIATION • focusyou feel about the issues of importance to our industry.As a voter and constituent, your voice is by far the most important to candi- dates and elected officials, and one that needs to be heard this year. During an October meeting of the Senate GA Caucus, Sen. Ben Nelson (D-NE) noted that misperceptions about the industry help explain why“general aviation is in peril at times.”The National Business Aviation Association (NBAA) agrees, and promises to continue to aggressively promote an understanding of business aviation through No Plane No gain (www.noplanenogain. org), the advocacy campaign which we jointly sponsor with the General Aviation Manufacturers Association.Despite the encouraging signs of support from policymakers, work must continue to correct the mischaracterizations about general aviation so 2012 will be solid recovery year for our economy and for our industry. You can count on NBAA to advocate tirelessly on behalf of GA this year, and we hope you will make your voice heard in 2012 as well. mGPS Interference Threat to U.S. Aviation System RemainsThe campaign to prevent interference (FCC) to conditionally allow a company calledLightSquared to develop 4G LTE wireless broadband services in radio frequency bands adjacent to those used by GPS receivers.The FCC waiver would allow development of a high-powered, ground-based wireless network on bandwidth previously allocated for Mobile Satellite Service (MSS) use. Based on feedback from public and private-sector GPS users, the FCC told LightSquared that it could not launch service until testing could be completed to determine the extent of the problems that the plan would cause.LightSquared filed the results of its tests on June 30 with the FCC, claiming minimal interference.However, the FCC suspended the waiver after industry tests revealed overwhelming evidence that LightSquared’s network interfered with weaker GPS signals on adjacent frequencies, and it is now deliberating on its next move.with global positioning system (GPS)receivers that so many pilots depend upon continues in 2012, building on a year-long effort to raise the alarm about the threat to the U.S. aviation system posed by a federal plan to expand wireless broadband access.NBAA has been advocating that the GPS technology that is relied on by general aviation (GA) aircraft operators to improve situational awareness, navigate within the national airspace system, and conduct instrument approaches to many GA airports is threatened by a plan to approve development of a nationwide mobile 4G network.As 2011 ended, the issue remained in limbo despite a growing chorus of opposition in Congress, other federal agencies, including the Federal Aviation Administration, and the aviation industry to a January 2011 decision by the Federal Communications CommissionJANUARY 2012 TWIN & TURBINE • 19
