When given 'cleared visual approach', this authorises the pilot to fly the route authorised until 5NM (generally continuing to the azimuth aid such as NDB, VOR etc) while descending in VMC and to then at 5NM adjust track as required to set up for the approach for landing.
Sorry Mirage 3, I haven't got a clue what you are talking about I realy haven't.
What authorised route?
Track to a beacon, why?
Whats 5 miles got to do with anything?
Sorry mate. Perhaps you do something different down under!!!!
