While the FAA in early October released its Notice of Proposed Rule Making (NPRM) covering future mandatory carriage of ADS-B avionics, serious questions have already been raised about it. Generally, it was expected that the NPRM would cover the whole spectrum of ADS-B applications and would provide clear guidance to corporate operators anxious to benefit from the system’s full capabilities. Instead, the document focuses on the  system’s “lower end” application, where the aircraft would appear only on ATC radars and on the cockpit displays of other, better equipped, airplanes.

Concerns have also been expressed about equipage costs versus benefits; the length of the transition to more advanced applications; the true ownership, control and certification of the system; and its overall security once operational.
