## Chapter 7: Radio Communication Procedures 

## Introduction 

Radio communications are an important aspect for the safe operation of aircraft in the NAS. It is through radio communications that pilots give and receive information before, during and at the conclusion of a flight. This information aids in the flow of aircraft in highly complex airspace areas as well as in less populated areas. Pilots can also send and receive important safety of flight issues such as unexpected weather conditions, and inflight emergencies. Although small UA pilots are not expected to communicate over radio frequencies, it is important for the UA pilot to understand “aviation language” and the different conversations they will encounter if the UA pilot is using a radio to aid them in situational awareness when operating in the NAS. Although much of the information provided here is geared toward manned aircraft pilots, the UA pilot needs to understand the unique way 

information is exchanged in the NAS. 

## Understanding Proper Radio Procedures 

Understanding proper radio phraseology and procedures contribute to a pilot’s ability to operate safely and efficiently in the airspace system. A review of the Pilot/Controller Glossary contained in the AIM assists a pilot in understanding standard radio terminology. The AIM also contains many examples of radio communications. 

ICAO has adopted a phonetic alphabet that should be used in radio communications. When communicating with ATC, pilots should use this alphabet to identify their aircraft. [Figure 7-1] 

## Traffic Advisory Practices at Airports without Operating Control Towers 

## Airport Operations without Operating Control Tower 

There is no substitute for alertness while in the vicinity of an airport. It is essential that pilots be alert and look for other traffic a when operating at an airport without an operating control tower. This is of particular importance since other aircraft may not have communication capability or, in some cases, pilots may not communicate their presence or intentions when operating into or out of such airports. To achieve the greatest degree of safety, it is essential that all radio- equipped aircraft transmit/receive on a common frequency and small UA pilots monitor other aircraft identified for the purpose of airport advisories.
