This hit me like a flying brick...
A windsock would be great but only give field elevation wind indications. A weather report in the tower would be impossible to retrieve in flight. How about...
A radio buffer message that mimics a real life ATIS. Such a feature tuned while in flight for a realtime wx report that could include surface winds, winds aloft, cloud locations and levels.
Ouch, that brick hurt =)
