The International Council of Aircraft Owner and Pilots Association (IAOPA) is pushing for the Loran-C ground-based navigation aid to be used for augmentation and back-up of global navigation satellite systems (GNSS). In October, IAOPA's World Assembly supported development of a second-generation GNSS, to follow the current global positioning system and Russian Glonass, but wants the current Loran to be retained, extended and improved to support GNSS. The Assembly also called for general aviation and aerial work aircraft to be exempted from any mandate to fit Mode S transponders, arguing that there is "no operational requirement or benefit".
