My first attempt at CAT2 was a disaster. 10 miles out from San Luis I made the exact call listed in the notes, but obviously substituting my call sign (GRS74) and the correct ATIS (foxtrot)
The reply back questioned if I was giving my call sign or tail number.. I replied it was my call sign.
ATC responded to tell me I didn't understand them. Then carried on talking to all the other pilots.. I flew a few circles wondering what to do, and not wanting to look stupid as it was very busy, I just disconnected .
Where do I go from here? What did I do wrong?
