I would have thought that a bush flying course is quite a waste of money unless you can do it in the equivalent of Universal Studios with all the instantaneous and variable special effects of the elements and the animals that one finds in Africa. I wouldn't have thought that the Namibian pilot is correct although it might have worked out for him hoodwinkwise. What defines a flight simulator, as in a three axis full motion machine, and what defines an instrument flight training simulator, as in a comfy chair and a screen that flaps around the horizon, could be two different concepts? Perhaps that's a reflection on aviation and safety in Maun? Too many MM simulator hours and not enough actual ones? Would a C206 type rating and no experience on type give you an edge? Others may be able to clarify that point for you? You could take the opportunity to self teach some tricky weight and balance examples including density altitude considerations. I wonder if it would impress at an interview if you demonstrated that you kew your way around a performance take off and landing graph, the very thought, WAT an idea!
