Some Govt Ops Exempt from Continuous ADS-B Transmission
National defense, homeland security, intelligence, and law enforcement entities will be allowed to terminate ADS-B transmissions during sensitive missions.

The FAA has issued an interim final rule that exempts certain government operations from the requirement that all aircraft equipped with ADS–B Out must transmit at all times. This rulemaking permits removing the continuous transmission requirement for “sensitive operations conducted by federal, state, and local government entities in matters of national defense, homeland security, intelligence, and law enforcement.”
