A visual observer call to alert pilots near the operation area should resemble which example?

A visual observer call to alert pilots near the operation area should resemble which example?

• A. VO calls only general traffic advisories.
• B. Zephyrhills traffic, unmanned aircraft Xray Yankee Zulu, five NM south at 400 AGL, three o'clock position.
• C. Zephyrhills traffic, unmanned aircraft Xray Yankee Zulu, five NM south of the airport at or below 400 AGL, three o'clock position of the Cessna, Zephyrhills traffic.
• D. Unmanned aircraft Xray Yankee Zulu in the area.

Answer: (C)

Clear and actionable traffic advisories rely on specifics: where you are, how high you are, and where other traffic is relative to you. The best call identifies the airspace by area, states the unmanned aircraft’s identity, gives a precise location and altitude, and then describes other traffic’s position so pilots can quickly picture the situation. Here, the message says Zephyrhills traffic, unmanned aircraft Xray Yankee Zulu, five NM south of the airport at or below 400 AGL, three o'clock position of the Cessna, Zephyrhills traffic. This provides: the area reference (five NM south of the airport), the altitude envelope (at or below 400 AGL), and a concrete bearing to another aircraft (Cessna at 3 o’clock) so pilots can locate both the UAS and the other traffic. It also clearly identifies who is speaking and keeps the advisory localized to the Zephyrhills pattern. The other options either lack a precise location or altitude, or give only vague or incomplete information, making it harder for pilots to maintain situational awareness.
