Chapter 13. Phraseology

Section 1. General

13-1-1. PURPOSE

This chapter prescribes standardized procedures and phraseologies to be used by flight service personnel when communicating weather and aeronautical information in broadcast, radiotelephone, and interphone communications. Where position or procedure-specific phraseology is required, reference is to be made to the relevant chapter of this order.

13-1-2. PHRASEOLOGY

The annotation PHRASEOLOGY denotes the prescribed words and/or phrases to be used in communications.

NOTE-
Specialists may, after first using the prescribed phraseology for a specific procedure, rephrase the message to ensure the content is understood. Good judgment shall be exercised when using nonstandard phraseology.

13-1-3. WORDS AND PHRASES

Use the words or phrases in broadcast, radiotelephone, and interphone communications as contained in the Pilot/Controller Glossary.

13-1-4. ANNOUNCING MISSING ITEMS

With the exception of RVR, announce the word “missing” when any item or component of a weather report is not reported, or in place of unreadable or obviously incorrect items or portions of weather reports. When appropriate, instead of speaking the name of several locations with missing reports, announce: “Other scheduled reports missing.”

NOTE-
On occasion, a parameter from an automated observation may be reported as missing in the body of the report but is available as a manually reported parameter in the remarks section. When the report is spoken, include the manually reported element in its proper sequence within the report.

13-1-5. ICAO PHONETICS

Use the ICAO pronunciation of numbers and, as necessary, individual letters for clarity. The ICAO radiotelephony alphabet and pronunciation guide are contained in TBL 13-1-1.

EXAMPLE-
``Appleton zero five zero radial three seven mile fix.''
``Reno localizer back course four mile fix.''
``Hobby Runway One Two M-L-S zero niner zero azimuth one two mile fix.''

b. When a fix is named, state the name of the fix followed by the phrase D-M-E fix or waypoint, as appropriate.

EXAMPLE-
``Shaum D-M-E Fix.''
``Shaum Waypoint.''

c. Use specific terms to describe a fix. Do not use expressions such as passing Victor Twelve or passing J Eleven.

13-1-21. RUNWAY CONDITIONS

a. State factual information as reported by airport management concerning the condition of the runway surface and describing the accumulation of precipitation. Furnish quality of braking action as received from pilots or airport management to all aircraft as follows:

1. Describe the quality of braking action using the terms good, fair, poor, or nil. If the pilot or airport management reports braking action in other than the foregoing terms, ask them to categorize braking action in these terms.

2. Include the type of aircraft or vehicle (if known) from which the report is received.

EXAMPLE-
``All runways covered by packed snow six inches deep.''
``Braking action poor reported by an F Twenty-Seven.''

3. If the braking action report affects only a portion of a runway, obtain enough information from the pilot or airport management to describe braking action in terms easily understood by the pilot.

EXAMPLE-
``Braking action poor first half of runway, reported by a Gulfstream Two.''
``Braking action poor beyond the intersection of Runway Two Seven, reported by a Boeing Seven Twenty-Seven.''

NOTE-
Descriptive terms, such as first/last half of the runway, should normally be used rather than landmark descriptions; e.g., opposite the fire station, south of a taxiway.

b. State runway friction measurement readings/values as received from airport management to aircraft as follows:

1. At airports with friction measuring devices, provide runway friction reports, as received from airport management, to pilots on request. State the runway number followed by the MU number for each of the three runway zones, the time of the report in UTC, and a word describing the cause of the runway friction problem.

EXAMPLE-
``Runway Two Seven, MU forty-two, forty-one, twenty-eight at one zero one eight ZULU, ice.''

2. Issue the runway surface condition and/or the runway condition reading (RCR), if provided, to all USAF and ANG aircraft. Issue the RCR to other aircraft upon request.

EXAMPLE-
``Ice on runway, R-C-R Zero Five, patchy.''

NOTE-
USAF has established RCR procedures for determining the average deceleration readings of runways under conditions of water, slush, ice, or snow. The use of RCR code is dependent upon a pilot's having a ``stopping capability chart'' specifically applicable to his/her aircraft. USAF offices furnish RCR information at airports serving USAF and ANG aircraft.
