When can an aircraft with ADS-B Out not operate in transmit mode?

An aircraft equipped with ADS-B (Automatic Dependent Surveillance–Broadcast) Out typically transmits its position and other information to enhance situational awareness and improve safety in the airspace. However, there are specific scenarios when transmitting this information can present risks, such as during law enforcement operations. In these cases, operational security may dictate that the aircraft does not operate in transmit mode to avoid revealing its location and mission details to unauthorized parties.

This situation highlights the need for discretion and the ability to adapt to specific operational contexts where broadcasting location data could compromise the safety or effectiveness of the mission. Other options do not accurately reflect the protocols regarding the use of ADS-B Out, as flying at low altitudes, through controlled airspace, or during night operations does not inherently prevent an aircraft from operating in transmit mode.
