Once upon a time AMMB (pre YMMB) was an all over field. I recall taking off and landing on 27 Grass towards the old tower.... Yes the runways were there, but no cones or gable markers. Once the runway lights went in, it all started to change. Back then just one frequency meant that calls were minimal on ground and in the air. Some change is good but one does have to ask if it could not be made more simple??? But then the procedures are now dictated by ICAO, so that is the way it is (sadly). Training is an issue with this also.
