ADSB-Out Transmission Loopholes To Track Aircraft Now Need To Be Closed, Pilots Say Capt. Jason Ambrosi, president of the Air Line Pilots Association, Int’l (ALPA), said the new FAA rule requiring radar monitoring of helicopters and airplanes in the same airspace is a meaningful step forward, and reflects the urgency that the aviation community has felt since last year’s tragedy at Washington National Airport. “Helicopter traffic and airline traffic operating in close proximity do not mix. Yesterday’s general notice, which now requires air traffic controllers to use radar to actively manage separation between these aircraft types at specific lateral and vertical distances, makes important improvements. However, Congress must go a step further and substantially reduce risk by ensuring, by statute, that ADSB-Out transmission loopholes are closed and are not subject to broad, subjective military discretion or waivers.
