The excuses about flying overweight in Maun always sound lame to me, and the problem isn't picking up a few overweight passengers or oversized bags, it is trying to squeeze 5 pax and their bags in a C206. If you see a 206 leave Maun with 5 pax and luggage it is almost certainly overweight. It has been long enough now that I dont remember the exact numbers but I knew how many standard pax and bags I could carry with a given fuel load and be legal. Even four pax is well over in some of the 206s i you have a lot of legs and are carrying a sensible reserve of fuel. At least when I was there all of the companies, even the ones that restricted 206s to 4 pax, knowingly dispatched aircraft that were grossly overweight. At least part of the reason young pilots with fresh comms are considered most desirable in Botswana is that the companies know that pilots working their first job are easiest to intimidate into flying aircraft loaded past their legal limits. To my knowledge no one has ever been fired in Maun for refusing to fly heavy, so I dont really understand why people still insist on doing it.
