Credit for this piccy goes to Herc Jerc.
This is another of my 'fav' spots...virtually directly under the Islander in this pic is the wreckage of another Islander that suffered a L/H prop hub failure as he was getting airborne...he was a top bloke and newly married....I'm still friends with his widow.
Kanobea departure
Need any more convincing to stay away from one way strips in the hills Sennadog?
I'm not sure who to credit this piccy to however while it is in PNG it is probably very representative of a 'worse case' strip that you might face solo in Africa...from piccies I've seen of typical African bush strips anyway. It's 580 meters and 2400' AMSL...at ISA + 20 that probably equates to 5000' DA (without doing the sums

)
Mt Bosavi
I don't want to scare you off having a fun trip...and by all means have a go at some real hard strips under supervision if you can organise such...but much more difficult than something like Mt Bosavi should be left to the pros my friend.

PS Have a look at the little gentle hills surrounding this strip and imagine what say 10 kts of wind blowing over them will do to your approach and particularly to your climb performance in a loaded C172 on a hot day
Imagine it wet and boggy in patches.
If you approach this adventure with brain engaged you'll have a ball and be a much better pilot after....best of British
