A system for sharing data between aircraft including a GPS unit for establishing a first aircraft's location and altitude from a network of global satellites and an automatic dependent surveillance broadcast (ADS-B) unit broadcasting a first aircraft's identification as well as it's location and altitude. The system also includes a mechanism for measuring the wind speed and turbulence at the location of the first aircraft and for broadcasting that information to other aircraft in the area. A second aircraft as well as other aircraft also include an ADS-B receiver for receiving such information.
