Military ADS–B Out Loophole Act

This bill narrows an existing exception allowing military aircraft to skip transmitting location data (ADS-B Out) during sensitive missions. It requires the FAA to define "sensitive government mission" narrowly - covering only active sensitive activities, not entire flights - and mandates agencies to report all non-transmitting flights with specific details like location, time, and mission type. Enhanced oversight includes GAO reviews, annual FAA audits, and congressional reporting on exception usage. These changes directly affect military and government agency aircraft operations that previously used the broader exception.
