Which of the following must NOT be included when forecasting air refueling requirements?

When forecasting air refueling requirements, the focus is on factors that directly impact the operational capabilities and logistics involved in air refueling missions. Aircrew availability, while important for overall mission readiness, does not directly influence the calculation of how much fuel is required. The key elements to consider in this context include:

• Fuel capacity: Understanding the maximum amount of fuel that can be taken aboard by the aircraft is critical for determining how much fuel will be needed during operations.

• Weather conditions: These can affect flight paths, fuel consumption rates, and operational safety, making them essential to consider when forecasting.

• Aircraft maintenance status: Ensuring that the aircraft are operational and maintained properly is fundamental to executing air refueling missions effectively.

Since aircrew availability pertains more to personnel management and scheduling rather than the direct logistics of fuel needs during a mission, it is not a necessary factor to include in the specific forecasting of air refueling requirements.
