The minimum regulatory fuel above the destination threshold shall be the minimum amount of fuel enabling the aircraft to reach the alternate airport. It is defined as follows:
Minimum fuel at destination (with alternate)
=
Alternate fuel + Final reserve fuel
If the expected remaining fuel on arrival at the destination airport is less than the alternate fuel plus the final reserve, the Captain must consider the prevailing traffic and operational conditions at the destination airport, along the diversion route to the destination alternate airport, when deciding whether to go on to the destination, or to divert.

Available fuel for holding
t =
Holding hourly consumption
