Definition
On the GPS Nearest Airport page group, the radio frequencies associated with a selected airport, such as tower, ground, ATIS, approach, CTAF, and UNICOM, listed so the pilot can review or load them directly into the radio without searching a chart supplement.
Plain English
The radio channels used to talk to the people at or near a specific airport, shown by the GPS so you can tune them quickly.
Context Anchor
Seen on the nearest airport page when a pilot is looking up which radio setting to use for a nearby airport or service.
Derivation
Frequency comes from the idea of how often something happens. In radio, it means how often a radio wave repeats each second, which is why each radio service has a specific number assigned to it.
Why Pilots Care
Using the correct frequencies ensures pilots can receive instructions, weather, and traffic advisories needed for safe flight.
Analogy
It is like choosing the correct station on a car radio. If you tune the wrong number, you may hear something else or nothing useful at all.
Intuition Check
Do not read frequencies here as meaning how often something happens in normal speech. In this context, frequencies are radio tuning numbers used to communicate or receive information.
Example Sentence 1
After selecting the nearest airport, she scrolled to the frequencies and loaded the tower frequency into the standby slot.
Example Sentence 2
Switching between the listed frequencies allowed contact with both ground and tower during the arrival.
