« on: May 12, 2024, 07:48:49 PM »A jetstream is just a wind, and I accounted for it in my calculation. A look at any jetstream map will show that they are predominently westerly in the southern hemisphere, which corresponds with my previous statement and, if it is assisting the eastbound flight will it not be hindering the westbound which is occuring simultaneously and at similar latitudes?
We've also done Jeran's thing before. Simultaneous to the "supersonic" speeds is a series of altitude changes which an F-16 would struggle with. Its just a batch of missing data on aircraft position; when it recovers the position data it integrates the delta-position over time to determine speed.
The speeds you provided for the Southern Hemisphere flights were too low. You stated "40 kts acting as a headwind hampering LAN801 and assisting LAN804". Jet streams are far faster, and we know that long haul flights take advantage of the Jet Stream.

"To be considered a Jet Stream, the accepted minimum speed limit is 60 knots. The speed of the Jet Stream is typically 100 kts (nautical miles per hour) but can reach 200 kts over North America and Europe in the winter. Speeds of 300 kts are not unheard of, particularly over south-east Asia."
Commercial flights would fly at the the plane's cruising speed + the Jet Stream speed. See this article from a Northern Hemisphere event over the Atlantic Ocean:

'In February 2019, a Virgin Atlantic plane flew at 801mph from Los Angeles to London, reaching its top speed over Pennsylvania thanks to a 200mph jet stream – although it slowed down to a mere 710mph once it hit the ocean. The aircraft – a Boeing 787 Dreamliner – usually has a cruising speed of around 560mph. Virgin founder Richard Branson described it as flying “faster than any other commercial non-supersonic plane in history.”'
