Final Answer:
When an attack upon CONUS or Canada by hostile aircraft is considered probable, imminent, or taking place, the commander of NORAD declares an Aerospace Warning Condition (DEFCON).
Explanation:
In the event of a potential or actual attack on the Continental United States (CONUS) or Canada by hostile aircraft, the commander of the North American Aerospace Defense Command (NORAD) has the authority to declare an Aerospace Warning Condition (DEFCON). This declaration signifies a heightened state of alert and readiness to respond to any threats to the airspace and security of the region. The decision to declare DEFCON is based on assessments of the threat level, intelligence reports, and the need to protect against potential airborne attacks that could pose a danger to national security.
