Question About Route From PER To JNB

Fri Sep 03, 2010 4:15 am

G'day guys

I freely admit that I have no idea regarding restrictions on quads and their allowed distances from usable airports since ETOPS rules have been changed to affect them.

So I'm asking for help regarding the route SA's A346's would take between PER and JNB. Is it any more complex than say SID out of PER to end of monitored airspace then great circle route to South African airspace followed by standard airways and STAR?

Does anyone know of regular intermediate waypoints and/or how far south they track?

Thanks guys

EDTO (replacing ETOPS) doesn't effect existing quad designs until 2017 and that's Australian registered quads, I have no idea about RSA registered quads.

Not too far off, in the Australian Airspace which goes out to 75 degrees east, the aircraft basically flies a flex track which changes depending on the winds for the day, at that point they change to Mauritius airspace, they have some designated routes to follow until 57 degrees east, then you enter the Johannesburg Oceanic FIR, at that point you can resume a flex track, around 37-40 degrees east you get into the Johannesburg FIR where normal airways are followed to JNB.

The orange line I sketched in may take the form of what a flex track may look like.
