Final answer:
This aviation regulation requires that when only weather criteria is used at the intended destination, fuel for holding must be included in the flight plan. If both weather and other operational criteria are used, holding fuel is not required.
Step-by-step explanation:
The subject of this question is related to aviation fuel planning and regulations, specifically within the context of the Air Force Manual (AFMAN) 11-202V3. This manual provides guidance on operational procedures for United States Air Force aircraft.
When an alternate airport is required, fuel required for holding at the intended destination must be included in the total flight plan fuel if only weather criteria is used at the destination. Fuel required for holding is not required if both weather and other operational criteria are used.
The rationale behind this requirement is to ensure that aircraft have sufficient fuel to proceed to an alternate destination if landing at the intended airport becomes impossible due to weather. Holding fuel ensures the aircraft can remain airborne while awaiting permission to land, or if a need arises to divert to the alternate destination.
