I'm afraid those are not well-defined in the AIP as belonging to specific pieces of airspace, so it's not practical for us to add them related to the airspace. Presumably to gain VFR penetration of that airspace you'd call up initially on Scottish Information or the existing ATS unit providing you with a service anyway?

I believe these frequencies are used for VFR Scottish TMA crossings above 5500ft ?
Callsign: Scottish Control

127.275 (from NW)
123.775 (from SW)
124.500 (from E)

Which specific frequencies were you referring to? We do not normally include "XX Control" services in SkyDemon data because those are usually associated with IFR operations.

I've noticed that the frequencies for VFR clearance through the Scottish TMA are missing in Skydemon Plan/Web above 6000ft?
