ARTCC: “Comanche 38 Kilo, traffic twelve o’clock, ten miles, a westbound Beech Baron one thousand feet below you.”
Comanche 38K: “Comanche 38 Kilo, looking for the traffic.”
ARTCC: “Baron 5 Foxtrot Lima, traffic twelve o’clock, niner miles, opposite direction PA-24 at niner thousand.”
Baron 5FL: “Baron 5 Foxtrot Lima, looking.”
ARTCC: “And Comanche 38 Kilo, you were requesting direct to where?”
?: “Uh, direct to Ketle.”
ARTCC: “Comanche 38 Kilo, I have your request.”
ARTCC: “Comanche 38 Kilo, climb and maintain one zero thousand.”
?: “Climbing to one zero thousand.”
You Talking to Me?
My question to you is this: After this radio exchange, who is climbing to 10,000 feet? If it’s Comanche 38K, everything is okay, because that pilot is climbing away from the converging traffic below him. If Baron 5FL took the call, the Baron is now climbing towards a potential collision with the Comanche above.
Blabbing on the Telephone
What is in play here? The pilot of Comanche 38K dropped his call sign and turned his communication into a telephone conversation. When we talk on the telephone, we don’t say:
“Mary, this is Bill. How are you?”
“Bill, this is Mary. I’m fine. How are you?”
“Mary, this is Bill. I’m good. Listen, I was calling to ask you . . .”
In a telephone conversation, we know who is at the other end of the line so there’s no need to use our “call signs.” Even in a conference call of 3 or 4 people, we can generally determine who is talking by voice recognition alone.
Voice Recognition is Not an Option
Not so on the aircraft radio. There may be 10, or 20, or 30 or more people on the same frequency. Most general aviation radios are not high fidelity. For these reasons, voice recognition, and telephone-style conversation has no place on an aircraft radio. The AIM and the FARs are unequivocal about what you are required to include with each radio transmission: always, always, include your call sign, period. It’s not only the law, it may save your life.
In our next class, we’ll examine the next part of a radio call: naming your location. That’s coming right up, so stay tuned.
