How long in advance must refueling schedules be submitted to ATC?

Refueling schedules must be submitted to Air Traffic Control (ATC) 24 hours in advance to ensure that all necessary operating protocols are followed and to facilitate optimal air traffic management. This lead time allows ATC to incorporate fuel operations into their overall flight management plans, ensuring safety and efficiency in airspace usage. Proper planning is crucial in military operations, where coordination among various units and branches is necessary, and advance notice allows for any potential conflicts with other scheduled flights to be resolved ahead of time. Additionally, the 24-hour lead time provides sufficient opportunity for ATC to assess the situational environment and make any necessary adjustments to accommodate the refueling operations safely.
