that there is no such thing for a fully qualified UK Flight Instructor to have an IR Instructor rating as a seperate attachment.
Nice wordsmithing but I think you mean that there is no requirement for an FI with the applied Instrument restriction lifted to have an IRI as a separate attachment but that there is in fact an IRI rating.
I am curious about one thing, does training with an Instructor who has the no Instrument restriction lifted but who does not have an IR count towards the 15hrs of applied instrument flight?
