why pilot when asked for spot wind, often answer 200 diagonal 30.
I find it a little bit useless, but may be I m wrong, for me makes more sense to just say: 200° 30kt
could find anything on cap 413 on that

The ATCO thinks he's a space cadet.

I hear "200 oblique 30" all the time. Those crazy pilots.

Is this the same as 'instant' wind as opposed to 2 min average?

Is this the same as 'instant' wind as opposed to 2 min average?I'm assuming no - I think they're talking about what the FMS says.

Just give them what you see on the dial or display. No diagonal, no trapezoid no nothing, just good old "wind 200 at 20 knots".

Some of you guys must be having trouble sleeping at nights :hmm:

Oblique is the correct word to use according to ICAO books.

You get many varied responses, from what is said here to "200 slash 30" "200 at 30" with or without degrees and knots being said. If a response wasn't understood, then the controller would just ask again, or find a better pilot.... :}

I don't really know why I say diagonal or slash, it's just that it's displayed on the nav display as 200/40 (on the Airbus) and I guess it takes an extra microsecond for my brain to translate / into "degrees".

How did you ask for the wind? Did you ask report spot wind? As I know, I usually say report wind conditions, or report wind aloft, is there any differences between these?

when at FL 370, to check the benefit to climb:
citronair 123, request spot wind at fl 390
BA123, could you report spot wind at fl 390
roger, wind is 200° 30kt, BA123 or wind is 200 diagonal 30, wind is 200 oblique 30
citronair 123, did you copy?

Try to say 200 at 20 over the HF sometimes and see how that goes down with the poor soul trying to hear what you're saying on the other end.
200 diagonal 20 is a direct reading out of the FMS (200/20) and at least what I was taught to use as it makes it clear that you are reading the wind at the end of a position report.
I guess the guys just continue to use that even on a clear and crisp VHF over Euroland.
