SNOWTAM decode

[Pilot Pete]

Any body got one they could reproduce here? Or a link to one on the web.......I can't find one anywhere!!!

Many thanks

I cannt copy the text in here. Here is a web site:

And here is a SNOWTAM

GG EHAMZQZX EDDFZQZX EKCHZQZX

C) 09 D) P)

R) NO S) 11070920 T) DESCONGELAMIENTO

Let me know if you find out the meaning

Pete,

Abridged from the FIH:
A- aerodrome
B- observation date/time
(For each runway):
C- runway
D- cleared length (if less than published)
E- cleared width (ditto)
F- deposits (nil, 1-9: damp, wet, frost, dry snow, wet snow, slush, ice, compacted snow, frozen ruts) for each third of total runway length
G- mean depth for each third of total runway length, in mm
H- braking action on each third of runway (1-5: poor-good)
J- critical snowbanks: height cm/distance ft, L/R
K- runway lights obscured (yes/no, L/R)
L- further clearance details
M- estimated time of clearance
N- taxiway available
P- taxiway snowbanks
R- apron
S- next planned observation time
T- remarks

Hope that helps!
Tocsin.

Thanks Fernando, looks like the Spanish AIP, that came up in a search I did but I didn't look at it as I can't speak much Spanish! Should have though as it has it in English too! Many thanks again, sim looming on Tuesday with LVP's and lots of snow in Geneva!

How's Luxembourg? I have a brother-in-law who lives there with his family and visited earlier in the year - thought the city was pretty nice.......beer was tasty too!

Thanks Tocsin

trying to decipher this though, which I can't quite match up with the examples given;

05620525

It's for Geneva rwy 05, so that accounts for the first two digits, I need my Jepp! The others are to do with deposits, braking action etc. I think! Just can't remember the order they are laid out in.

Pilot Pete,

You’re looking for a decode of the eight figure group appended to METAR reports. This is different from SNOTAM form CA1272 and uses different fields.
Try this link to an MS Word doc. http://www.safe-flight.net/snotam-english.doc

Pete,

Without the fields, its guesswork! Immediately following the runway designator (field C) should be available runway length (D) and width (E) - but both are optional.

I *guess* that the interesting bits for testing purposes are deposits (F) and braking action (H) - depth (G) doesn't seem to fit the data.

So:
05 runway designator
620 slush/wet/clear
525 good/medium-poor/good

is my stab at it, but the first third of the runway looks odd! Basically, more info on fields required...

The UK AIP has full details of SNOWTAM codes here

Hi, Pilot Pete. You are probably looking at a MOTNE report, which is different from a SNOWTAM.

A MOTNE report is an 8-figure group appended to the METAR, where figure:

1 and 2 =Runway Designator
3 = Type of deposit
4 = Extent of Coverage
5 and 6 = Depth of deposit
7 and 8 = Braking Conditions.

The MOTNE report is derived from the same observation/measurement as the SNOWTAM.

Nick.

[Pilot Pete]

Thanks for all your replies guys

You were indeed right, it was the MOTNE 8 digit code for runway state. The catch was in the sim briefing which called it a SNOWTAM! Cunning these training captains aren't they? Had to go into work to have a look at the JEPP and it all became clear........except for Geneva rwy05!!!!! Wish me luck for 6am tomorrow morning........

Good luck! ;)

Pete,

Rwy 05
Slush (6)
Between 11% and 25% contaminated (2)
5 mm deep (05)
.25 (Poor) braking coeeficient (25)

I've had the mel and ddg out for the rest of it - email me.
