How do the aircraft loadouts affect fuel usage?

[skorpio667]

Hi all,

With the upcomming air-to-air refueling overhaul and future dedicated AAR-waypoints, I'm trying to figure out how an aircraft's loadout is affecting fuel usage, so I can incorporate Remaining Fuel/when to AAR (and how long it wil take) into my Excel Strike Planner.
I can't find a datafield in the database giving me that info, I think fuel usage is calculated by the loadout's weight fraction. But if so, how?

Could anyone shed some light on this?

Hi Skorpio,

In table DataLoadout there is a column named 'PayloadWeightDragModifier' that determines how much extra fuel aircraft burn per minute per kg of payload (drop tanks not included).

So first you need to sum up the overall payload weight, and then do this:

PayloadPenalty = (PayloadWeightDragModifier * (FuelConsumptionPerMinute * PayloadWeight )) / 100
FuelConsumptionPerMinute += PayloadPenalty

Thus, if aircraft drop their payload at max range, there will not be any drag on the return leg. Hence the need to know how much ordnance is planned to be expended at what distance from base [8D]

Aha! Thanks

Lots of work to do now [:D]

Is value of PayloadWeightDragModifier column depends on value of DefaultMissionProfile column?

No.
