its easy to get involved with what you can do and base your teaching upon that. personally the stabilisation point has taken the fun out of the visual approach especially as we are being monitored by optic.
its great to cream a large a/c around the corner at 300 ft and land but its not really what the punters are paying for.
what students need, i believe is achievable targets and goals.
my first student target was early go around from base leg if it looked doubtful, not wait till final when it was only usualy worse.
the next target was never below 400 feet for the turn onto final. that target would be adjusted on base.
the next target was a final 200 feet stablisation in regard to airspeed, centreline and height .
i cant remember what i taught for a blocked runway go around target but guess it was 100ft
icarus i suppose you are correct, its good to teach someone a faster approach for the reasons you state, but where do you draw the line in what you teach. i would prefer to spend time on teaching oval circuits!
ps you may think from the above we did a lot of go arounds. we did!
i would rather use a good go around a s the basis for first solo than a good landing!
