ADSB Inhibit Question for MEA LI Draft RFP The US Customs and Border Protection Air and Marine Operation (CBP AMO) needs the capability to fly certain sensitive missions without communicating its position and identifiers in an easy to exploit manner by unauthorized observers. In accordance with the Code of Federal Regulations (14 CFR) 91.225, all aircraft operating in controlled airspace are required to be equipped with Automatic Dependent Surveillance-Broadcast (ADS-B) equipment and 14 CFR 91.227 outlines ADS-B equipment performance requirements.

It is known that any Mode-S transmission by an aircraft is easily exploitable, especially the ICAO registration number and the aircraft’s location. Therefore, CBP AMO is interested in a pilot-selectable law enforcement mode, which would mask or inhibit the transmission of Mode S and ADS-B replies. As safety is a top concern, the maximum amount of TCAS functionality must be persevered.

CBP AMO is interested in learning from industry what potential solutions they would recommend, what the related costs and schedules would be, and what impacts or risks are involved especially with respect to safety and FAA airworthiness to deliver the MEA with a law enforcement mode ADS-B.
