What must daily refueling schedules include when submitted to ATC facilities 24 hours in advance?

The daily refueling schedules submitted to ATC facilities 24 hours in advance must include requested refueling levels, requested time of use, and call signs. This information is essential for air traffic controllers to manage and coordinate air traffic effectively. Knowing the requested refueling levels allows controllers to understand how much fuel the aircraft needs for its operation, which influences flight planning and safety considerations.

The requested time of use is crucial as it helps ATC to plan for peak usage times, ensuring that the refueling operations do not interfere with regular traffic or create delays. Call signs are important for identification purposes; they help ATC clearly communicate and coordinate with specific aircraft in the airspace. Thus, all these elements work together to ensure a smooth and safe operational environment during refueling processes.
