Hey there,
After only one hour of these things I'm not suprised you're not happy!
It took me about 4 hours just to get the circuits right, remembering to keep centerline after liftoff, remembering to keep at the circuit level, remembering to make the pre - landing checks 'BUMPFISH', call abeam on downwind, lower each stage of flap at the right time etc etc.
These are all important to do well, as a good approach makes for a good landing.
I'd say - concentrate on your height, and speed mostly as if you're 200ft too high on final it makes for a poor landing! Always aim for the numbers and maintain your approach speed to the knot, as if you're too fast or slow it has a big impact on the quality of the landing.
As with a lot of other people, after my first hour I was feeling as if I wouldn't be unable to cope with everything which you have to do in that short space of time.
Give it 3 hours and you'll be fine - You'll have BUMPFISH off in 0.5 seconds! (I'm just kiddin' for those who may jump me for rushing important checks
)
