Having flown for ten years in africa including bukavu and recently in a b747. All i can say is that nothing changes. Still no navaids outside the capital,very poor coms,outside of capital wx reporting just guesswork. Notams etc useless. I treat overflying africa like overflying oceans. If anythig happens you are one your own, night time each country has only I lighted runway if it has power. The dark continent indeed. Fly safe.
