Advanced Flight Model is really hard, but one can develop strong skills with effort. Yet one thing that pilots can't control in KOTH is that they have no option to pre-configure their fuel loadout (or ammo loadout in the case of armed helis or jets if you'd like to extend this that far). In AFM, the weight of the fuel and even the individual passengers and their respective loadouts all realistically contribute to the gross weight, right? And because AFM flight characteristics are so affected by weight, pilots should be allowed to have some say in how much their helicopter weighs, to the extent that a real pilot would by not taking on more fuel than is safe or necessary.
If one wants to carry a full load of 7 or 8 passengers in the Hummingbird or RHS Littlebird, respectively, and especially if the passengers are fully-kitted, this can't be done unless maybe the helicopter is already low on fuel. I'm not entirely sure what the limits are, as I usually have to repair before I get low on fuel, although when I do go long periods without refueling, the flight performance gets demonstrably better. Being able to control this as a real pilot would, at least while in AFM on KOTH, would be really cool. I suppose it's not necessary for SFM, although maybe not a bad idea to enable. Can you add a laptop near the repair pad to enable such loadout functionality?
Would be super cool for us dedicated AFM pilots!
