Claim Text:
1. An aircraft radio circuitry arrangement of an aircraft radio for reducing effects of Common Traffic Advisory Frequency (CTAF) radio congestion, comprising: circuitry configured for receiving at least (i) an indication of an airport, (ii) a geographic range surrounding the airport, and (iii) a CTAF frequency associated with the airport; circuitry configured for determining a first distance between the aircraft radio and the airport; circuitry configured for providing an indication of a first squelch value based at least in part on (a) the determined first distance between the aircraft radio and the airport, (b) the geographic range surrounding the airport, and (c) an assumed fixed transmission signal strength; and circuitry configured for providing an indication of a second squelch value based at least in part on (a) a determined second distance between the aircraft radio and the airport, (b) the geographic range surrounding the airport, and (c) the assumed fixed transmission signal strength, wherein the second squelch value is operable to alter a signal strength threshold associated with the aircraft radio audibly emitting received CTAF radio broadcasts as a function of the determined second distance between the aircraft radio and the airport.
