Pity that Derek does not appear to have read the references provided by
Rory. The items on the SGU website relate to the Scottish TMA around
Edinburgh and a local agreement between the SGU and NATS Edinburgh that
permits easier access to the South though defined routes, an agreement
between the BGA, SGU and Scottish Air Traffic relating to crossing the
airwayS viz P600 andB226 subject to prior notification and radio calls, and
an agreement between the BGA, SGU and the Scottish Control centre that
permits gliders from Portmoak access to the Northern part of the Scottish
TMA and southern part of P600 at weekends. No mention of the Scottish Wave
boxes in any of these.
