[Quick disclaimer, my WiFi is stable, so slow or unstable WiFi/internet shouldn’t be the issue this time.]
I’ve been controlling at various airports on TS1, and a few times recently the METAR has shown as “Unavailable”.
This causes all of the runway numbers in the map view to become active (green). However, I’ve noticed that the ATC menu options (like taxi to, takeoff at, etc.) still show certain runways as active but others with tailwinds (red) or crosswinds (yellow). Usually, these ATC menu runway labels show the complete opposite of what the winds were before “Unavailable” happened.
I’m not 100% sure, but I think the pilots’ weather is usually still being updated. This may cause confusion, as their active runways might differ from the ones in my ATC menus. They might think I’m sending them to an inactive runway on purpose because it appears as active on my screen.
So far, I have only seen this happen in the US, but I don’t control in other countries very often.
Notice the screenshot I attached. It lists the METAR as “Unavailable” in the top-left corner and the Weather as “N/A”, and it shows all runways as active. However, a pilot I talked to who was near that airport at the time told me only 22L and 22R were active, but the others weren’t. In this case, however, in the “Taxi To” menu, the active runways matched up with the map instead of showing 04L and R as active and 22L and R as inactive.
My main questions are: Does anyone know why the METAR stops working, and is there a fix for it? (Or is it just a bug, or is it some other reason?) How/why does it still suggest aircraft to taxi to certain runways/decide to make certain runways active and others not in the ATC menu, even if the weather is unavailable? And does this affect/confuse pilots too, or is this weather issue just for me or ATC?
Hope this isn’t a duplicate post!
