Cant remember any approach aides working Gbadolite, and trust me not a viable alt at all, last time i saw the fire truck well come to think of it what fire truck, lets put it this way, even the locals ask you for water when you step out the door........... he he the Great Thief's gold terminal is still there all be it a bit plundered. Some of the "last stand warbirds" are still there guarded like they will take off to defend the empire against.............
Try for some of the UN bases in Congo some have the GPS let downs available, they were published if I recall and at least you get some fire protection, Mbandaka, Gemena, Kisingani if you can make it, but your basically up poop street in this part of the world.
Did some flying there and if you want a good place to go when the chips are down try Berberati about 180nm to the west, got a good strip of tar or whats left of it. Been a while so dont take my word for it....
