EA
If entering a MATZ on the weekend (ie no response from the unit), when and if you cross the final approach path, use caution in case you meet someone on final for some obscure reason. If the ATZ is also inactive, you can fly through it as well.
It's probably worth putting in at this point that
ALL Military ATZ's in the UK are notified as 'H24', therefore there is never a time when they can be deemed 'inactive' unless specifically NOTAM'd as such
Also - yes - Scottish do have radar data as the controllers actually carry out the 'FIS' function as part of the lower sectors duties, unlike London where it's a separate function, staffed by FISO's.
