I did a flight in a C206 from Miami to Tanzania in May. The main problem with planning the flight is where to get av gas. There are very few places available in North Africa.
We had a company called overflight help us with finding the availability of fuel and getting us clearances. They were so helpful with everything. I had some planning questions as I had never done anything like this. The bloke who owns overflight helped me out loads. and you can contact them around the clock. Their web site is
www.overflight.co.uk I cant remember the name of the bloke who helped out.
We didn’t need their help until we got to Africa. Then we needed to get the clearances. they needed to know when we were going to be going through the different countries to organise the 48 hour windows. i think some were 36 hour windows of when we could pass through.
The planning was easy in the end. I got the jep charts that were bloody expensive and then went to places that had cheap fuel. We went to Guernsey to fill up. Then on to Dubrovnik. Then to Luxor. I think Luxor was the only place with av gas in Egypt. and they knew it, as it was expensive. That flight was about 10.5 hours long. The next place with fuel was Djibouti. So it was another long flight. Djibouti is an awful place, hot humid and filthy. Then we went on to Nairobi, where the plane got re registered, then down to TZ. I don’t know about av gas in the rest of Africa.
We were flying IFR for all of the legs. Made things a lot easier. We had HF but it packed up. and in the end we were ok without it. We lost contact plenty of times. And even entered Sudan without being in contact with anyone. There weren’t even airliners flying about who could relay. I was worried about getting shot down at first but in the end no one seemed to care. We had a GPS, and without it navigation would have been a nightmare. Distances between nav aids were huge.
I hope some of that info might be helpful. At first I thought I was in way to deep having never done anything like that, but in the end it was quite easy.
If you have any other questions I will be happy to help,
Good luck
