Even though they give you a Squalk (1155.) they have no Radar screen, and my guess is that they just have a large Chart with Post-It notes on, to record any Notams or Events.
I think you will find that both London and Scottish information are slightly more technical than that.
Although not classed as a radar both London/Scottish have a FID " Flight Information Display" This is an anti airspace infringement tool and is there to assist the FISO in preventing a possible airspace/danger area infringement.
I think you may now realise reading the previous post's that my colleagues at London Information are very well appreciated by all that take the time to call....like wise up here in Scotland I am pretty sure that the service provided by myself and colleagues at "Scottish Info" is thought to be of some use and appreciated too.
