Radio Communication Procedures

Understanding Proper Radio
Procedures

ICAO has a phonetic alphabet that should be used

Traffic Advisory Practices at Airports without Operating
Control Towers

All radio equipped aircraft should transmit/receive ona common frequency

May have a full/part-time tower or flight service station (FSS)

Full or Part-time universal communications station (UNICOM)

Or no station

Understanding Communication on a Common Frequency

CTAP (Common traffic advisory frequency) is designated for the purpose of
carrying out airport advisory practice while operating to or from an airport without a
control tower

CTAF may be a UNICOM, MULTICOM, FSS or tower frequency

Multiple Choice

What abbreviation does common traffic advisory use?

• MULTICOM

• UNICOM

• CTAF

• FSS

Communication/Broadcast Procedures

MULTICOM frequency of 122.9 is used at non-towered and does not have FSS or
UNICOM

Multiple Choice

What MULTICOM should you use if an airport does not have one?

• 122.9

• 12.29

• 222.9

• 123.9

Recommended Traffic Advisory Practices

A remote pilot in command is not required to communicate with manned aircraft in
the vicinity of a non-towered airport

You must be familiar with phraseology, traffic patterns, and radio procedures

Look to a navigational chart to find frequency for the airport, if none is given use
MULTICOM 122.9

Recommended Traffic Advisory Practices

When a manned aircraft is inbound to a non-towered airport, the procedure is to
have the pilot broadcast when they are 10 miles from the airport

Includes direction from airport

Example:

Town and Country traffic, Cessna 123 Bravo Foxtrot is 10 miles south inbound for
landing, Town and Country Traffic

Recommended Traffic Advisory Practices

Manned aircraft will

Make another broadcast when entering the traffic pattern

Make broadcast when executing landing

Make broadcast when landed and clear of the runway

Same procedure should be used when taking off from a nontowered airport

Conclusion

UA pilots are not required to monitor radio communications but it can improve
safety around the airport if they do

UA pilots should not broadcast unless there is an emergency situation

Multiple Choice

Do UA pilots need to announce takeoff/landing on the radio?

• TRUE

• FALSE
