Speeds

State the separate digits of the speed followed by the word "knots." The controller may

omit the "knots" when ordering a speed adjustment: "Reduce/Increase speed to two five

zero."

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.
