Looking to find more info on on-board weather sensing systems available to pilots. To clarify, this does not include ground-sourced ATC relayed observations. My scope is weather information directly available to the pilot from the aircraft's on board systems.
I'm looking specifically at major airlines in the US, and the mandated minimum requirements for those aircraft.
If anyone could tell me a bit about these systems, or let me know where I could find more information, I would very much appreciate it!
Thanks
