COM Radio Operation
SkyView Pilot’s User Guide - Revision S 11-11
Using the TWR, ATIS, GND, and ATC Buttons
When an airport is loaded on the radio, press the TWR, ATIS, GND, and ATC buttons to send
frequencies associated with that airport to the standby frequency. Repeated presses of these
buttons will cycle through all available frequencies of that type (for example busy airports may
have multiple tower frequencies):
TWR: Tunes tower, unicom, and multicom frequencies.
ATIS: Tunes ATIS and other weather/information frequencies, including AWOS, ASOS, AWIB,
and AWIS frequencies.
GND: Tunes ground control frequencies.
ATC: When on the ground: Tunes pre-taxi, clearance, and departure frequencies associated
with an airport. When in the air: Tunes departure, center, and approach frequencies when
associated with an airport.
