Shy Torque - That would be most helpful. This simple question I posed does perhaps illustrate the confusion that exists on this (and no doubt many other) issue. It is also perhaps indicative of a general confusion in aviation here in the UK about so many things. We fly in very crowded skies, with rules and regulations more akin to another age and even the people who fly/control for a living cannot agree on so many things. What chance has average PPL to know what he can/cannot do without spending so much time researching before every flight?
