Query about map symbol

[Foxendown]

Gretings all, I may have missed this in the documentation, but I can't find anything about the symbol showing an aircraft in a red circle with a diagonal line through it. I expect it's something obvious (I've not been playing this game long). Does it mean no flying because of weather conditions? Hopefully someone out there who's still playing the game can put me right. Many thanks.

You are correct: the "plane prohibited" symbol means "no-fly due to weather". (I usually shut it off-- I find it annoying.)

Thanks, much appreciated.
