RUNWAY REPORTS EUROPE.
Information on RWY conditions expressed by one or more 8-figure groups appended
to the METAR.
MOTNE runway reports code AABCDDEE.
|
1st and 2nd figure RUNWAY DESIGNATOR
PARALLEL RWY:s The right RWY is identified by adding 50 to the Designator, e.g
77=27R, while the left RWY only the RWY figures appears e.g 27=27L
The figure 88 instead of a RWY designator indicates that conditions reported
apply to all RWY at the Aerodrome.
The figure 99 instead of a RWY designator indicates that a previous RWY report
is repeated.
3rd figure TYPE OF DEPOSIT
|
- 0= CLEAR and DRY
- 1= DAMP
- 2= WET or Water Patches
- 3= RIME or FROST (<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 RWY clearance/de-icing i progress.
4th figure EXTENT OF CONTAMINATION
- 1= 10% or less of RWY covered
- 2= 11% to 25% of RWY covered
- 5= 26% to 50% of RWY covered
- 9= 51% to 100% of RWY covered
/= NOT REPORTED e.g due to RWY clearance or de-icing in progress.
5th and 6th figure DEPTH OF DEPOSIT
- 00= less than 1mm
- 01 to 90= depth in mm, e.g 23=23mm
|
- 92= 10cm
- 93= 15cm
- 94= 20cm
- 95= 25cm
|
- 96= 30cm
- 97= 35cm
- 98= 40cm
|
99= RWY not operational due to snow, slush, ice, large drifts or RWY clearance.
Depth not reported.
//= Depth operationally not significant e.g with ice or rolled snow, or not measurable e.g
RWY wet.
7th and 8th figure BRAKING CONDITIONS
Either the measured Friction Coefficient or an estimated Braking Action is reported as
follows
FRICTION COEFFICENT
Reported figures from 01 to 90 represent FC, e.g 05=FC 0.05, 28=FC 0.28
BRAKING ACTION Reported by following code figures
- 91= POOR
- 92= MEDIUM/POOR
- 93= MEDIUM
- 94= MEDIUM/GOOD
- 95= GOOD
- 99= UNRELIABLE, BA and FC not possible to assess, misleading, e.g in case of
aquaplaning.
//= RWY not operational, BA and FC not reported.
