First, the Checklist for the Cargo missions -- Second, Fuel and Passenger missions:
MS needs to add one item to the top of the checklist for all cargo missions:
[ ] Pick up nearest wrench and beat copilot into unconsciousness.
Seriously. They're always telling you that you are too heavy for this runway, have too much fuel, "When you fly with me you fly by the book," yadda fricken yadda. (Actually, when you fly with me, you keep your mouth shut or I'll kick yerass out the door at 5,000 feet.) If you want to do something useful, then tell me ahead of time that the destination airfield for our current night mission has no freakin' runway lights!
No matter what airfield, the Fuel popup at the airfield (F key) always tells me that the Maule is overloaded when I have 4 passengers, even if I remove all the fuel. (Is basic math not Microsoft's strongest subject?) Never mind, I always manage to take off fine regardless of the cargo or passenger load, even at short strips.
