I don't know if I am maybe the only one not knowing this - but the gliders in Far Cry 2 work somewhat strange. Or at least their physical model is either highly accurate or plain wrong.

Intuitively I was flying the glider always at the speed it took off - that is, no leaning forward, gaining speed - expecting I'd get farthest using that technique. After all, drag is way lower when going slow (drag is coupled to velocity squared).

However, in order to get as far as possible you need to tuck in right after start and collect some serious speed. Then the glider is leveling out itself. When you reach the farthest possible distance (depending on the slope and formation of the landscape of course) you gradually pull out the speed and exchange it for height gain to get a little bit farther. When you pull too much you might "stall" and the glider drops a bit, don't get to this point.

Using this I managed to get from Dogon Village all the way to the safe house in the north east to it - over the crest.

So maybe they implemented some really strange glider behaviour - or they managed to adapt some sort of polar curve and put the best glide angle a bit behind the velocity you take off with. But the difference must be huge :)

That's cool! I've only gotten that glider half way up that crest. I'll have to experiment a bit more and try to do that.
