Pretty unlikely now with :-
a) The rules on displaying the sectors bandboxed and
b) The backup radar coverage at Aberdeen.
I have previously limited the service to FIS when bandboxed and possible conflicting military activity. Usually for en route northbound a/c and reinstated for the release to PB.
Probably the only time I would now consider it is with PB radar out and activity milling back and forth to D809N.
