its not really designed for when you can get any other service.
Its for when you can't get Scottish info.
To be honest if you fly above 1000ft agl its not really meant for you either. Although it may be of use in the Great Glen.
Its for when the helicopter boys are long lining working. So they are clashing with low level mil traffic because they are sub 500ft most of the time.
In all the years flying in the highlands apart from once which was my fault being below 1000ft agl taking photo's you don't have a problem GA with the low level traffic. And that includes the period with the build up for Gulf I and II.
