From Clarens – 0nly noticed this about a month ago and in particular, from our house’s aspect (a touch W of North; deliberately laid out that way by me !) we normally see Jnb/ Pt. Eliz. Traffic quite a distance ‘over there’ and four fingers at arm’s length above the local horizon. E. London stuff goes nearly over the top of us: Upper Airway Quebec 7 crosses between BHM and Clarens. We’ve been shuffled along it twice on our way to Perth, to catch both the Great Circle route AND the Jetstreams (if any ). Coming back, we generally made landfall over Richards Bay. I don’t think Flightradar24 would help; it’s too compressed.
I’ve at last got some gen that sounds reliable, regarding the contrails we see over us that now seem to bend off to the Left for traffic from E. London heading up to you.
It seems they have altered the hitherto straight-in approach to Heidelberg and the Jo’bg TMA by kinking the airways off twenty degrees or so to Port when traffic is abeam Reitz. There never used to be any sort of beacon at Reitz. My informant is a local man who is a Captain for one of the smaller private airlines in the Middle East; but he would have access to the relevant Notams.
I wonder why they’ve done this? Presumably it helps traffic management in the final approaches to the pair of “ 03’s “ at Smuts but I can’t quite see how.
Incidentally, looking-up on the days when weather patterns are conducive to contrail formation, shows just why airways are 10 miles wide: traffic paints their passage all over the sky, sometimes and for all the world to see! I wonder if any senior Instructors ever think of showing their class of students going through IFR training what the results of their sloppy flying looks like, from the ground?
