(Might I suggest some of you read back through the thread before posting the same questions over again?)
Can someone please explain to me why you have this requirement to track via the STAR on a visual approach (have I understood correctly?). Possible reason would be traffic density and R/T congestion, but we don't seem to have a problem at Wellington for example.
Thats exactly why STARS are promulgated - see AIP:
12.1.2 STARs satisfy the requirements of:
a. noise abatement procedure tracks;
b. airspace segregation for ATC purposes;
c. maximum traffic handling capacity; and
d. reduction in pilot/controller workload and air/ground communication
requirements.
Tracking Requirments:
Tracking requirements (visual app): ATC AU-705 (1.7.5.4) Jepp reference.
Visual approach in CTA
a) maintain track/heading on route authorised by ATC until:
(1) by day, within 5NM of the aerodrome; or
(2) by night.
- IFR flight, within the prescribed circling area.
- VFR flight, within 3NM of aerodrome and aerodrome in sight.
b) From this position the circuit must be joined as directed by ATC for
approach to nominated R/W (The STAR does this).
Example:
para b) above refers to the instructions from KOUPA and LISSA below. That is your instruction. It does not say track as you like. The Visual Approach is the descent.
