arrow???
don't worrie too much about your medical condition in tanzania. no need to worrie at all... they would give a first class to a man with one leg if he would ask for one.
and the chief would just look at your logbook and/or your credentials before the test flight.
the problem you must ponder is if you will ever get a job down there...i hear that things are starting to look a bit on the down side...
saying this...all the best and happy landings.
tanzania is a great place... if you don't mind a bit of dust here and there and some power cuts, you will have a great time!!!
