Flying Aid, is some of the most challenging flying around, due mostly to the fact that modern countries with ATC / Radar etc don't need aid, so you are flying in countries where you have to be allot more vigilant for everything, people, dogs, cars, cows and everything else that can cross a runway running in front of you when you are about to touch down, Big Russian machines who over exaggerate their true position, or who cant talk English. Weather that comes and goes with no reports, so runways that are there one minute are not the next, Friendlies who are not that friendly when it suits them. What I am trying to put across is that most of the big aid agencies want 700 hrs TT for a C208 Co-Jo
, A C130 would require 3-4K plus type rating and time on type, preferably ex Military for a Co-Jo. But you can give Safair or Trans-Afrik a call to get the low down.
Good luck
