Seeking and obtaining a statement from the CAA that AVGAS is a "Specialist Fuel" (their words) which will assist AOPA in their representations to the Treasury in relation to taxation on AVGAS following the EU directive on fuel taxation a while ago.
A specialist fuel could, arguably, have its own tax-code and be taxed "differently" to car fuel...
May mean AVGAS goes up by 2p/L rather than the projected 30p/L as would happen if the EU directive were followed and no separate tax code applied.
