I will quite often limit service from below, if you are at the base of solid radar cover between Glasgow and Inverness, and Stornoway and Inverness, especially if the aircraft is flying below FL100. Advisory routes W3D, W6D and A1D are 50 miles plus from the radar heads (Tiree, Aberdeen and Lowther Hill (by Abingdon on the A74) ). So you have very little warning of fast jets pulling up out of the highlands. It is only fair to warn you of that.
We do not have composite radar, instead we have two 17 inch computer displays with one radar selected on each. Not easy when you really need three radars selected .....
Lowther for Glasgow, Islay, Campbeltown area
Tiree for West Coast traffic, to/from Bennie and St.Ornoway and transatlantics in/out of Scottish TMA
Aberdeen for Inverness ins/outs on W3D
and then you often have to reselect the radio transmitter site for each transmission (Lowther, Tiree and Stornoway) as the ac at Campbeltown can't hear you on the Stornoway Tx, and vice versa.
... and then you have to operate a 200 mile sector on a s### 17 inch screen
but I digress ...... our equipment is mince .... roll on New Scottish Centre
