What dictates when air traffic control squadrons are activated for deployment?

The activation of air traffic control squadrons for deployment is primarily influenced by the operations tempo. This refers to the operational pace and demand for air traffic control services, which are determined by current military operations, training exercises, or missions that require their expertise. When there is an increase in operational activity or deployment needs, air traffic control squadrons are activated to ensure that airspace management and flight safety are maintained efficiently. This flexibility allows for an agile response to the changing requirements of military operations.

The other options do not take precedence in determining deployment activation. Time from last deployment may influence readiness but does not dictate activation. The Air National Guard training schedule is focused on training activities rather than deployment decisions. Lastly, while Congress may have long-term plans for military readiness, the ten-year deployment plan would not directly influence the immediate activation based on current operational needs. Thus, operations tempo is the most relevant and immediate factor for determining when air traffic control squadrons are deployed.
