Thanks for the posts guys.
I am unfamiliar with the SRA / PAR differences in the UK so I am learning slowly. I didn't realise that altitude/range checks were not given on a PAR. Am I correct then to assume that you may not get any glidepath info from the controller if you are on the profile or would they advise you occasionally that you are "on glidepath"?
Also, do you generally respond to instructions for an SRA only (unless they tell you otherwise)???
BOAC, descended cos we were VMC and saw that we were going above the profile.
