Without a doubt, the most startling advances in aviation continue to be in the realm of avionics: they are having a significant effect on flight operations and ultimately–witness the accelerating move to NextGen–on ATC. Some aircraft owners and operators view the upgrade mandates (such as ADS-B out) to meet NextGen’s equipage requirements as an unnecessary burden, but that shouldn’t be the way we characterize it, according to Ric Peri, vice president of government and industry affairs at the Aircraft Electronics Association.
ADS-B, he suggested, “is nothing more than modernization. The industry modernized aviation 25 years ago with the introduction of GPS, and the FAA is now modernizing its air traffic system to take advantage of it.” In other words, the ATC infrastructure is finally going to realize the benefits that GPS promised, from pinpoint radar-less surveillance to opening precision GPS approaches into many more airports. In fact, the number of Waas LPV approaches in the U.S. reached 3,951 at 1,746 airports in November, and 1,002 of these airports have no ILS. Precision GPS procedures are available in other regions, among them Canada and Europe.
