The term initial radio contact, or initial callup, means the first radio call you make to a given facility, or the first call to a different controller or Flight Service specialist within a facility. Use the following format: 1. Name of facility being called; 2. Your full aircraft identification as filed in the flight plan; 3. Type of message to follow or your request if it is short, and 4. The word "over," if required (typically omitted, except for communications via a remote communication outlet or in cases when it is necessary to confirm the end of a transmission). Example: "New York Radio, Mooney Three One One Echo, over." When the aircraft manufacturer's name or model is stated, the prefix "N" is dropped. The first two characters of the call sign may be dropped only after ATC calls you by your last three letters/numbers.
