On Tuesday 10 May 2016 London VAAC will occasionally be issuing exercise Volcanic Ash products (including ash concentration charts). The products will appear on these, and linked, pages and will be clearly marked as TEST or EXERCISE. Please do not take any action on these products. In the event of a real eruption this message will be removed and all issued products will appear without the TEST or EXERCISE header.
