AirspeedWind (повідомлення UORB)

Wind estimate (from airspeed_selector).

Contains wind estimation and airspeed innovation information estimated by the WindEstimator in the airspeed selector module.

This message is published by the airspeed selector for debugging purposes, and is not subscribed to by any other modules.
