Radio Communications Phraseology

b. Air Ambulance Flights.

Because of the priority afforded air ambulance flights

in the ATC system, extreme discretion is necessary

when using the term “MEDEVAC.” It is only

intended for those missions of an urgent medical

nature and to be utilized only for that portion of the

flight requiring expeditious handling. When re-

quested by the pilot, necessary notification to

expedite ground handling of patients, etc., is provided

by ATC; however, when possible, this information

should be passed in advance through non−ATC

communications systems.

1. Civilian air ambulance flights responding to

medical emergencies (first call to an accident scene,

carrying patients, organ donors, organs, or other

urgently needed lifesaving medical material) will be

expedited by ATC when necessary. When expedi-

tious handling is necessary, include the word

“MEDEVAC” in the flight plan per paragraphs 5−1−8

and 5−1−9. In radio communications, use the call

sign“MEDEVAC,” followed by the aircraft registra-

tion letters/numbers.

EXAMPLE−

MEDEVAC Two Six Four Six.

2. Similar provisions have been made for the use

of “AIR EVAC” and “HOSP” by air ambulance

flights, except that these flights will receive priority

handling only when specifically requested.

3. Air carrier and air taxi flights responding to

medical emergencies will also be expedited by ATC

when necessary. The nature of these medical

emergency flights usually concerns the transporta-

tion of urgently needed lifesaving medical materials

or vital organs. IT IS IMPERATIVE THAT THE

COMPANY/PILOT DETERMINE, BY THE

NATURE/URGENCY OF THE SPECIFIC

MEDICAL CARGO, IF PRIORITY ATC ASSIST-

ANCE IS REQUIRED. Pilots must include the word

“MEDEVAC” in the flight plan per paragraphs 5−1−8

and 5−1−9, and use the call sign “MEDEVAC,”

followed by the company name and flight number for

all transmissions when expeditious handling is

required. It is important for ATC to be aware of

“MEDEVAC” status, and it is the pilot’s responsibil-

ity to ensure that this information is provided to ATC.

EXAMPLE−

MEDEVAC Delta Thirty−Seven.

c. Student Pilots Radio Identification.

1. The FAA desires to help student pilots in

acquiring sufficient practical experience in the

environment in which they will be required to

operate. To receive additional assistance while

operating in areas of concentrated air traffic, student

pilots need only identify themselves as a student pilot

during their initial call to an FAA radio facility.

EXAMPLE−

Dayton tower, Fleetwing One Two Three Four, student

pilot.

2. This special identification will alert FAA

ATC personnel and enable them to provide student

pilots with such extra assistance and consideration as

they may need. It is recommended that student pilots

identify themselves as such, on initial contact with

each clearance delivery prior to taxiing, ground

control, tower, approach and departure control

frequency, or FSS contact.

4−2−5. Description of Interchange or

Leased Aircraft

a. Controllers issue traffic information based on

familiarity with airline equipment and color/

markings. When an air carrier dispatches a flight

using another company’s equipment and the pilot

does not advise the terminal ATC facility, the possible

confusion in aircraft identification can compromise

safety.

b. Pilots flying an “interchange” or “leased”

aircraft not bearing the colors/markings of the

company operating the aircraft should inform the

terminal ATC facility on first contact the name of the

operating company and trip number, followed by the

company name as displayed on the aircraft, and

aircraft type.

EXAMPLE−

Air Cal Three Eleven, United (interchange/lease),

Boeing Seven Two Seven.

4−2−6. Ground Station Call Signs

Pilots, when calling a ground station, should begin

with the name of the facility being called followed by

the type of the facility being called as indicated in

TBL 4−2−1.
