105. BASIC COMM PROGRESSION
Every conversation with a controlling agency or service follows a specific progression: the
initial call, subsequent calls (directive and informative), and terminal call.
Remember there will only be one controller on each frequency. In other words, Tower will
never be on approach's frequency nor will approach be on Tower's.
Controllers will be talking to other aircraft on that frequency so be alert for your call sign. To
avoid missing ATC radio calls, a technique that works well in the aircraft is to stop or break up
ICS communication when a controller or other aircraft talks on the radio. When a call is heard
over the radio, everyone in the aircraft stops talking and listens to ensure the call is not directed
to your aircraft. This technique eliminates missed ATC calls. Initially, this is challenging but as
more experience is developed, this becomes second nature.
Proper communication involves the realization of the current phase of flight and making correct
and timely responses.
Initial calls: These calls introduce yourself to the controlling agency or service for the first
time. The call MUST be in proper format and MUST include your full call sign since its primary
purpose is to positively identify yourself to the controller.
