Help with a METAR code
 
Hi,

I was flying yesterday and I got the METAR for Madrid via ACARS. After the usual weather report, it had the following on the end

R99/29//95

I don't know what this means, can anyone help please?

Thanks

RWY wet BA good
 
Hi small_dog,

that seems to be a SNOWTAM in METAR style.

A repeated previous report (99) (the following slash (/) is often used as visual divider from the rest of the report) saying that water or water patches (2) are covering 51% to 100% (9) of the runway with no measurable or significant depth (//) and breaking action good (95)

In other words, the runway seems to be wet and BA is good.

Rwy condition
 
Off the top of my head, R99 means all runways. 2 I don't remember 9 means greater than 51% (of the rwy length) //is a measure of breaking coefficient. 99 is eh.. Good? :-)
Hope it helps

rwy condition ??? have my doubts. should be 8 digits then.
btw: all rwys = 88

Hi,

Thanks for all the replies, that's really useful to know! I thought it might have been a snowtam of sorts but I've never seen that style before.
Thanks once again for the replies
Cheers
:ok:

@Airbus_a321:

In my experience things like R25R/29//95 or RWY25R/29//95 (should have been 7529//95) are somewhat common around Europe.
