What can one add after Chimbu Chuckles' excellent post?
Flying in and out of short, rough, high strips in the mountains, there are 2 points which were impressed on me which could come in useful:
1. Have a plan for what you're going to do if you mess up your approach BEFORE you start the approach. As Chimbu Chuckles says, no special techniques are required other than speed control and an accurate touchdown point. If you miss your touchdown point on a short strip with high density altitude, can you go around safely? If not, which direction should you steer after touchdown for the least unpleasant crash? If you touchdown halfway down a short strip, and then realise you're not going to make it you'll probably hit whatever is at the end of the runway. There might have been something much nicer to hit to the left or right!
2. On a short field takeoff, one thing which goes without saying is USE ALL OF THE STRIP. People often don't.
In SE England, there used to be an excellent short strip near to Canterbury (close to the village of Boughton, in between Faversham and Canterbury), but I'm not sure if it is still open. It had an obstructed circuit (hills), a bit of a slope to the first part of the runway followed by a level section and a broken tarmac / gravel surface. If it is still open it's most definitely not somewhere to go and discover solo. I think it may have been closed down, though. The M2 motorway is in a cutting at the end of the runway, and more than 1 pilot has ended up on the road, usually after taking off uphill, getting airborne in ground effect on the level section, then stalling over the road as the ground falls away...
Have fun in SA. Watch out for the poisonous spiders!
