As to whether the lifestyle in Francistown is better than Maun...well thats debateable. I dont know what factors they use to make that decision
If there is a huge demographic then why hasnt the CAAB improved their infrastructure such as facilitating a proper course structure from PPL to CPL and instructors. In order for a training organisation to be profitable they cant have their students going just to PPL!
I am not disputing the fact that there is a demographic but the way it is right now there is surely no way they can make a profit out of 10-20 PPLs which is 500-1000 hours per year...even so that amount of students will make it hard to survive as it is IMHO.
