Thanks for your replies - my question was somewhat rhetorical however.
I have noticed of late various operators when cleared VSA manouevring off the STAR track. I assume this was interpreting the AIP extract as shown above by
Jack Red:
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 emphasis in the replies seems to be on para a).
However, re-read para b).
"As directed by ATC" means as directed by the STAR as best I can interpret - in many STARS there are circuit joining instructions .e.g. Track 275 for a 3.5NM Final.
Any comments?
