However, the FISOs can - and in Scotland do - ask for information from you in such a way that it is obvious that you are about to bust controlled airspace.
So, yes, they cannot say: our radar shows you about to enter controlled airspace, please turn left.
They can say: your route takes you close to Glasgow's Class D, are you aware of line features that will help you identify the zone boundary (or some such words!)
I an sure the good folk will come up with some real world examples!
