Thanks for your feedback Rotatingturbine. I'm sure those procedures you have listed are correct for YBSU, but there does seem to be some significant differences to class D operations at Bankstown/Camden from what have read over the last couple of days. It seems that every class D airport makes up there own procedures - the lack of standardization if puzzling and confusing to a student pilot. For example:
"CALLSIGN is overhead (VFR reporting point), (altitude), (atis receipt), (any additional information, over water, over land etc.), requesting inbound clearance."
At other class D airports AFAIK, there is no need to explicitly ask for 'clearance' (i.e. just say 'inbound')... it is implied and granted if your tower responds with your call sign.
"ALLSIGN, make (circuit leg) for RWxx. Report (circuit leg).
Ok so we are cleared to operate into the Class D at our assigned altitude, and we are able to descend to circuit height if able. Once you report on that leg, they will generally issue landing clearance. Remember, you are cleared to descend to circuit height as soon as you are in the zone."
At other class D airports AFAIK, when told to report at a certain leg you, you must descend and be at circuit height before entering the zone, unless told otherwise.
"CALLSIGN, roger.
Cleared to enter Class D at altitude specified in inbound call. Must stay in current track until cleared otherwise. "
At other class D airports AFAIK, if the call-sign is just acknowledge, then you are cleared to commence descent and must enter the zone at circuit height on the appropriate leg.
Pretty confused about this whole process!!!
