I'm in the same case as you guys. Don't know anything. Nothing about GA on metoffice, nothing on NATS... I was planning a local tonight, I prefer to postpone it... Dont know what those ashes exactly do to our cylinders, don't know if the air filter stop that crap efficiently enough and I don't want to discover it in flight.

Barton info says VFR OPR SHOULD EXERCISE EXTREME CAUTIONO AND MUST ASSURE THEMSELVES THAT THEIR INTENDED FLIGHT CAN BE CONDUCTED IN A SAFE MANNER.
Suspect they dont know much more we do!
"In a safe manner" LOL.
