Section 3. Use of Terms

  1. USE OF CONTRACTIONS AND ABBREVIATIONS
  1. Contractions and abbreviations designated for ICAO usage as specified in FAA Order JO 7340.2, Contractions and ICAO Document 8400, ICAO Abbreviations and Codes, must be used in the NOTAM system. When an ICAO-usage contraction is not available, plain text is required, except for the list of differences in Appendix C.
  2. For indicating abbreviated days of the week, use a hyphen to indicate successive days or each day can be specified individually separated by a single space; for example, MON-FRI means Monday through Friday, whereas MON WED FRI means Monday, Wednesday, and Friday.
  3. Use the Pilot/Controller Glossary to define terms in the NOTAM system.
  4. Location identifiers used in the NOTAM system are those contained in FAA Order JO 7350.9, Location Identifiers.
  5. Use applicable contractions and abbreviations published on instrument flight procedure charts in the text of FDC NOTAMs relating to approach and departure procedures.
  6. Contractions written in the singular form decode to mean both the singular and plural.
  7. Contractions written in the past tense decode into both the past and present tense.
  1. EXPRESSION OF TIME IN THE NOTAM SYSTEM
  1. The day begins at 0000 and ends at 2359.
  2. Times used in the NOTAM system are Coordinated Universal Time (UTC/Zulu) unless otherwise stated, as in the body of Temporary Flight Restrictions, and must be stated in 10 digits for the year, month, day, hour, and minute (YYMMDDHHMM).
  3. When describing a daily schedule, Sunrise-Sunset (SR-SS) may follow the day(s) or “DLY”.

EXAMPLES-

MON-FRI SR-SS
DLY SS-SR
DLY SR-1800
TUE 2300-SR

  1. UNITS OF MEASUREMENT

Specify the unit of measurement in distance, height, altitude, or weight. When using an abbreviation, do not add a space between the measurement and the unit of measurement. At a minimum, latitude must be 6 digits and longitude must be 7 digits.

EXAMPLES-

500FT
12500LB
5NM
6.2NM
20MIN
1HR
330DEG
305DME
402646N0795856W
402646.25N0795856.95W

  1. USE OF VIRGULE (/)

The use of virgules should be limited to separate runway pairs (RWY 03/21), combining positions and affected frequencies (LOCAL CTL/CD), and equipment, affected components and frequencies (ILS GP/OM/MM, VOR/DME 111.0/CH77).

  1. RUNWAY IDENTIFICATION
  1. Specify the runway identification as it is published, including the leading zero (0).
  2. List the runway identifications in clockwise order beginning from the 1 o'clock position.
  3. Use runway pair when applicable.
  4. Indicated runways should be in feet for sections, closure of a movement area, or portion thereof. Partial runway closures must be indicated by feet, for example, E 500FT.
  5. Identify runways with the prefix RWY followed by magnetic bearing indicator.

EXAMPLES-

RWY 03/21
RWY 03
RWY 21

  1. Differentiate parallel runways by using the runway designators followed by L (left), R (right), and C (center). Use L, R, and C with runway designators only.

EXAMPLES-

RWY 03L
RWY 03C
RWY 03R

  1. Where the magnetic bearing indicator has not been established, identify the runway to the nearest eight points of the compass.

EXAMPLE-

…RWY NE/SW…

  1. TAXIWAY IDENTIFICATION
  1. Identify taxiways with the prefix TWY followed with the taxiway designator letter or letter/number as assigned.
  1. Describe a taxiway that does not have an assigned designator as adjacent to a runway or direction from runway.

EXAMPLES-

…TWY PARL TWY ADJ RWY 09/27…
…TWY PARL TWY…
…TWY EAST/WEST TWY CLSD…

  1. When a cardinal direction is used to describe a taxiway condition, the word describing the direction must be spelled out in full to ensure that the cardinal direction is not mistaken for a taxiway designator; for example, “EAST,” “WEST,” “SOUTHWEST.”
  2. Describe a helipad located on a taxiway as:
    …TWY HELIPAD 3…
  3. Describe a runup pad located on a taxiway as:
    …TWY A RUNUP PAD…
    …TWY C RUNUP PAD FOR RWY 27…
  1. Keyword TWY may be followed by designator “ALL” to indicate every taxiway at an airport, even if there is only one taxiway as: (Can be used as “TWY ALL EXC TWY X” if needed.)
    …TWY ALL…
  2. For multiple taxiways, use a comma between each designator. Do not add “TWY” prior to each individual taxiway identifier.

EXAMPLE-

…TWY B3, C…

  1. Taxiway segments may be identified using geographic points, cardinal directions or by feet.
  1. Geographic. Identify geographic segments using “BTN” and “AND”.

EXAMPLE-

…TWY A BTN TWY B AND RWY 01/19…

  1. Cardinal Direction. Identify directional segments using a cardinal direction.

EXAMPLE-

…TWY C NORTH OF RWY 09/27…

  1. Dimension. Identify the amount of a taxiway affected by feet.

EXAMPLES-

…TWY DD NORTHEAST 500FT…
…TWY A BTN TWY L AND 300FT WEST OF TWY L…

  1. Multiple taxiways. Indicate a series of taxiways using a hyphen between the first and last descriptors.

EXAMPLE-

…TWY A1-A6…

NOTE-

The example includes taxiways A1, A2, A3, A4, A5 and A6.

  1. Multiple segments. Indicate all taxiway segments by starting with the contraction “TWY”, and then add the segment description separated by commas.

EXAMPLES-

…TWY A BTN TWY C AND TWY G, TWY B NORTH 100FT, TWY ALL NORTH OF RWY 09/27…
…TWY A BTN RWY 01L/19R AND RWY 01R/19L, TWY B BTN RWY 01L/19R AND RWY 01R/19L, TWY C BTN RWY 01L/19R AND RWY 01R/19L CLSD…

  1. Multiple segments (Single Taxiway). Indicate multiple segments of a single taxiway with each portion beginning with TWY.

EXAMPLE-

…TWY A EAST OF RWY 01L/19R, TWY A WEST 100FT…

  1. Full taxiways and taxiway segments separated by commas share the same condition for example: CLSD, NOT MARKED, WIP SN REMOVAL, etc.

NOTE-

Snow removal must only be issued when snow removal is actually occurring.

EXAMPLES-

…TWY B1, B2, F, TWY B BTN TWY B10 AND TWY B8 WIP SN REMOVAL…
…TWY C BTN APCH END RWY 04R AND APCH END RWY 04L CLSD…

NOTE-

NOTE-
The originator may always issue multiple NOTAMs to ensure clarity.

  1. APRON IDENTIFICATION
  1. Identify aprons with the keyword APRON followed with the apron designator. There is no requirement for RAMP or APRON to be part of the name of the surface. Keyword may be followed by designator “ALL” to indicate every APRON at an airport, even if there is only one APRON as: (“APRON ALL” or “APRON ALL EXC WEST APN” if needed.)

EXAMPLES-

…APRON TERMINAL APN… (Where the name is Terminal Apron)
…APRON MAIN TXL C… (Where the name is Main)
…APRON ALL…
…APRON J RUNUP PAD……APRON HELIPAD A1…

NOTE-

This example describes a helipad (A1) that resides on a ramp. Only this helipad (A1) has an abnormal condition.

  1. SPOTS, GATES, HARDSTANDS, etc., can be used as geographical reference points to delineate a section on aprons or taxiways, but do not meet NOTAM criteria as its own “attribute”.

EXAMPLE-

…APRON TERMINAL RAMP BTN GATE 3 AND SPOT 4…
