Also while flying to airports, I hear people talking to Approach control or Tower and when calling in their inital call they will say something like "Cessna 12345 inbound for landing with the ATIS" Arent you suppsed to specify the ATIS ( Information Alpha, Broav, Charlie, etc? Again, these professional and veteran pilots go off and do there own thing. I guess they think it sounds cool. But it is not the standard
