Blue Hauler
You're right, accurate speed control is essential landing on a short strip, as is touching down at the correct point.
If approach speed is controlled using the traditional technique and the aiming point is overshot then one simply applies full power and goes ‘round - not so bad.
Usually, yes. But in the mountains, this just isn't an option. Nor is undershooting. If things go wrong, the best you can hope for is a low-speed impact at the uphill end of the strip.
There is not really a lot of difference between the two techniques, however. On an approach to a mountain strip, final approach is initially flown at a level attitude until the glideslope is intercepted, then approach power is set and the aiming point is aimed at. If speed is too high, you reduce power.... but, if you always fly approaches in the same way, the only reason for the speed being too high is that your approach is too steep and you are above the glideslope.
The power reduction that I use to control speed is therefore effectively controlling my height!
