Figure 24 — Sectional Chart Excerpt · FAA-CT-8080-2H, p. 2-23
Figure 24 shows CADDO MILLS (7F3), a non-towered airport, with "122.8" marked by a circled C in its data block. What does this indicate about 122.8?
Why: FAA-CT-8080-2H Legend 1 defines the circled-C symbol as the Common Traffic Advisory Frequency (CTAF). At a non-towered field like Caddo Mills, the CTAF is the frequency manned traffic uses to announce position and intentions since there is no tower to provide separation.
Assumes every airport needs ATC authorization, but Caddo Mills is non-towered with no tower to grant one — the CTAF supports self-announcing, not an authorization request.
Confuses the CTAF with an automated weather frequency; Caddo Mills' data block lists only "122.8" with the circled C, and the AWOS-3 133.425 printed nearby belongs to Majors (GVT), a different airport.
