Africa?!
You as a pilot are at risk flying in Africa above the Limpopo. You are a meal-ticket, a bribe only if you are lucky. A 3 month ransom in some hole for a "MilliOn Doo-allars" is NOT unlikely.
DO have bribe money with you, DO take all the advice from the above, DO have all your shots, DO follow very strict personal hygiene.
You may have a good income, but it comes with high personal risk.
