Then Asia definetly doesn't belong to ICAO :}

They even switch on all the lights (incl landing lights) when they enter the RWY, even if they don't move and haven't received any clearance to move.

Re the Airbus thing: I think that there are different versions: Older Airbusses had the NAV or logo switch while newer MSNs react on the input of gear and/or flaps extension. Check your local FCOM...

Correct procedure depends on operators and manufacturers policy.
There is no international policy regarding taxi light operation. I find stationary aircraft easier to spot if they leave them on. However I do know of one Euro airport where service vehicles are not allowed to cross the apron when an a/cs taxi light is on .
In my opinion nav lights are best left on. Saves having to remember them, particularly on those high latitude flights.

Back to Nav lights

In Australia, according to CASA reg CAR196 (I think), nav lights must be on at all times in flight.

I am not sure how that works with say PA44 operators when the nav lights are on the 3 greens are dimmed so much that you cannot see them by day.... :}

"In Australia..."
Ha ha; oh, if I had a dollar for every time...!
Kind of like an aviation Galapagos Islands, it has a evolved differently to the rest of the world due to its isolation. I am joking of course, but you have to admit there is a grain of truth to it with regards the beaurocracy!
I recall an occasion during a stint in G/A after leaving the military (where policy was nav lights stay on) a colleague was off on his first job in a Seneca (I think). He came up on the company frequency saying "Help! I can't get a gear down indication". Spent 20 minutes cycling the gear and generally troubleshooting before the Chief Pilot came in, yawned, then picked up the mic and said " you wouldn't have your nav lights on by any chance would you?".

"Er, yeah....Oh!"

Yep, I thoroughly agree there. Been there done that (except I worked it out myself!)

No need to liken oz to the Galapagos - look at our own fauna that's evolved in isolation. Mammals that lay eggs for god's sake! Maybe Oz aviation suffers from the Australia Effect!:p

As for our rules, there are many many ones where the rest of the world sees it practically. Mind you there are a couple of rules here (like no mandatory Alternates) that allow aviation to continue unabated...!
