DECODE OF EIGHT FIGURE GROUP APPENDED TO MOTNE/OPMET BROADCASTS

DECODE OF EIGHT FIGURE GROUP APPENDED TO MOTNE/OPMET BROADCASTS

The first two digits indicate the Runway Designator. The third digit indicates the Runway Deposits.

The fourth digit indicates the extent of runway contamination.

The fifth and sixth digits indicate the depth of deposit.

The seventh and eighth digits indicate the friction co-efficient or Braking Action.

RUNWAY DESIGNATOR (FIRST AND SECOND DIGITS)

The two digits correspond to the runway designator (e.g. 09, 27 etc.). In the case of parallel runways, the ‘Left” runway is indicated by the designator only (e.g. 09L as 09) while the “Right” runway has 50 added so that 09R becomes 59 and 27R becomes 77. Whenever all runways are affected the figure group 88 will be used.

NOTE: 99 may sometimes appear as the first two digits. This does not purport to be a runway indicator but means that the information is a repetition of the last message because no new message has been received in time for transmission.

RUNWAY DEPOSITS (THIRD DIGIT)

The runway deposit expressed as a single figure as follows:

0 — Clear and dry

1 — Damp

2 — Wet or water patches

3 — Rime of frost covered (Depth normally less than 1mm)

4 — Dry snow

5 — Wet snow

6 — Slush

7 — Ice

8 — Compacted or rolled snow

9 — Frozen ruts or ridges

/ — Type of deposit not reported (e.g., due to runway clearance in progress).

EXTENT OF RUNWAY CONTAMINATION (FOURTH DIGIT)

The extent of runway contamination is expressed as a single digit in accordance with the following scale:

1 — Less than 10% of runway contaminated (covered)

2 — 11% to 25% of runway contaminated (covered)

5 — 26% to 50% of runway contaminated (covered)

9 — 51% to 100% of runway contaminated (covered)

/ — not reported (e.g., due to runway clearance in progress).

DEPTH OF DEPOSIT (FIFTH AND SIXTH DIGITS)

The depth of deposit is indicated by two digits in accordance with the following scale:

00 less than 1mm

01 = 1 mm

02 = 2 mm etc.

10 = 10 mm etc.

15 = 15 mm etc.

20 = 20 mm etc. up to 90 = 90 mm

NOTE: Code 91 is not used.

Thereafter, the depth is indicated by: 92 = 10 cm

93 = 15 cm

94 = 20 cm

95 = 25 cm

96 = 30 cm

97 = 35 cm

98 = 40 cm or more

99 = runway or runways non-operational due to snow, slush, ice, large drifts or runway clearance, but depth not reported.

// = Depth of deposit operationally not significant or not measurable.

The quoted depth is the mean of a number of readings or, if operationally significant, the greatest depth measured.

FRICTION CO-EFFICIENT OR BRAKING ACTION (SEVENTH AND EIGHTH DIGITS)

The friction co-efficient is denoted by two digits or, if the co-efficient is not available, the braking action is denoted by two digits.

a.Friction co-efficient EXAMPLE:

28 - friction co-eficient 0.28

35 - friction co-efficien 0.35 etc.

b.Braking action

95 = Good

94 = Medium / Good

93 = Medium

92 = Medium / Poor

91 = Poor

99 = Unreliable

// = Braking action not reported; Runway not operational, Aerodrome closed; etc.

NOTE 1: Where Braking Action is assessed at a number of points along a runway, the mean value will be transmitted or, if operationally significant, the lowest value.

NOTE 2: If measuring equipment does not allow measurement of friction with satisfactory reliability, which may be the case when a runway is contaminated by wet snow, slush, or loose snow, the figures 99 will be used.

DECODE OF EIGHT FIGURE GROUP APPENDED TO MOTNE/OPMET BROADCASTS

EXAMPLES

NOTE: The occasion may arise when a new report or a valid report is not available in time for dissemination with the appropriate METAR message. In this case, the previous runway state report will be repeated, as indicated by the figures 99 in place of the runway designator.

99421594 — Dry snow covering 11% to 25 % ot the runway: depth 15 mm; braking action medium to good.

14//99// — Runway 14 non-operational due to runway clearance in progress.

14////// — Runway 14 contaminated but reports are not available or are not updated due to aerodrome closure or curfew, etc.

88////// — All runways are contaminated but reports are not available or are not updated due to aerodrome closure or curfew, etc.

14CLRD// — Runway 14 contamination has ceased to exist.

(No further reports will be sent unless recontamination occurs).
