What is the aircraft identification used in the initial contact phrase?

• A. HAWK SIX SIX SIX CHARLIE BRAVO
• B. HAWK SIX SIX SEVEN CHARLIE BRAVO
• C. HAWK SIX SIX SIX CHARLIE ALPHA
• D. HAWK SEVEN SEVEN SEVEN CHARLIE BRAVO

Answer: (A)

In initial radio contact, you identify the aircraft by giving its type, then the three-digit identification spoken one digit at a time, followed by the two-letter callsign spoken with the phonetic alphabet. This setup—type, digits, and two-letter code—ensures a clear, unique identification over the radio.

So, “HAWK SIX SIX SIX CHARLIE BRAVO” communicates that the aircraft is a Hawk, has the ID 666, and uses the Charlie Bravo callsign. The other options would indicate a different numeric ID (like 667 or 777) or a different two-letter callsign (for example, Alpha instead of Bravo), which would not match the intended identification and could cause confusion.
