Frank, If you want to know how involved and intense an SRA is, go onto VATSIM on a Cix VFR Club "Gloucestershire Tuesday" fly into EGBJ in IMC and ask the controller at Gloster (Mike Pike) for an SRA. He likes doing them as it really gives him (and you as pilot) some work to do. Not to be undertaken lightly. If you haven't had the training as a controller to do one, you did right to refuse, as you would probably have messed up, and you wouldn't have enjoyed the experience one bit. :-) Peter
