If you were to aim to land anywhere else other than the tochdown zone which is generally 300 metres past the threshold on an instument runway and marked with the 'chequered' paint markings either side of the centre line, or failed to follow the glideslope information provided by approach path indicators (papis, vasis et al ) to landing on non instrument runways, then you would not get past day one of your initial conversion course with an airline. Surely it is best to tech the correct technique for each type of runway that could be used, short fields, grass strips etc require different techniques, but if you can land on the TDZ on a large runway, then you must have the skill to land just past the threshold on a short strip if required.
From experience, if you do not need to land on the threshold, then the extra fifty feet height you will have over it is an extra safety margin aginst windshear etc. It's for free as well - and I'm all for that.
BTW, regarding leaving the carb heat on until you are runway vacated - does not the carburettor heater on most piston engines bypass the airfilter and it's use decrease the volume of charge in the cylinders due to the warmer air being induced?.
I thought the proper way to use it was to turn it off prior to landing so that full power will be available for any go-around and to prevent engine damage on the ground due to f.o.d. ingestion.
