Atpl question : meterology
Hi everybody,
May someone assist me with the translation of those numbers please?
Where is it explained in the book? I have never seen this kind of code so far (i'm currently on chapter 18).
The exact question is :
What would the code 01640428 tell you about the condition of the runway?
a) it's raining
b) it's snowing
c) braking co-efficient of 0.28
d) it's broken
many thanks for your help.

01 - Runway 01 (88 = all runways, 77 = 27R i.e. subtract 50, 27 = 27 or 27L)
6 - Slush (0 good, 9 very bad)
4 - The extent, think this is an error as it should be either 1, 2, 5, or /
04 - Depth of deposit: 4mm
28 - Braking coefficient 0.28
Great pictorial example of how to decode here: www.b737mrg.net/downloads/b737mrg_snowtammetar.pdf

This is a 'state of the runway' group for METARs - authority is WMO Pub.
no. 306 (Manual on Codes, Vol. I.1, Regulation 15.13.6.
See amendment to this regulation via Corrigendum to Supplement No. 6.
If in EUR then see also EUR FASID, Part III-AOP, AOP Attachments (5 Jun 09).
Attachment A.
For the 'SNOWTAM format' itself, see ICAO Annex 15, Appendix 2.

If this is a real question, it is about the information that is contained in a Runway State Message. Therefore, A and B can be discounted because that information is contained in a METAR. D has to be excluded because that would be mentioned in a NOTAM or on ATIS. Therefore, the answer is as Rapid Ron used to say "C or the longest answer."
