wind readings

[skiper27]

Example:

- company limit is 30 kt cross wind

- wind is 030 / 23
( on our met station there is always displayed max wind although it is not > 10 kt than 2 min average wind)

so we see

030 / 23 kt 32 max

gust should be forwarded only if >10 kt than 2 min average

so if I don't read it to pilot ( and I am not obligated ) they can land and if I read it it is higher then limit thay can not land)

What is your practice?

Thanks.

I don't know which part of Europe you are from, so don't know anything about your local or national regulations. But unless you have a specific instruction to the contrary I would pass all relevant met information to a pilot, whether you are required to or not. He will know his particular company regulations on this matter, so let him make the decision, based on the most accurate information you can give. In any case, you can't possibly remember wind limitations for each and every aircraft type and each and every operator.

Two answers two different opinions that is why I asked this.
According to regulations we give gusts if >10 kt over 2 min average but my personal opinion is that when>10 kt difference is gust it is to big difference because sometimes is 2 min average near someones limit and there are maximum of 9 knots and not to read that if something happens that would probably be matter of investigation.

I would provide what Annex 3 said - the two minute average plus gusts in excess of 10kt together with variations in direction over the two minutes.

Is there a specific reference in Annex 3 regarding two minute average??

It's not standard but I read it is "030/23 maximum 32 knots". I know it's not a gust and I don't have to give it but it's better to give all of the information if it's relevant.

If that <10kts is directly from the side (or worse, the tail, when landing downwind), I would consider it significant, even though it might remain within the met rules for "reporting not required" and definitely pass it to the pilot. If consistent, I'd put it on the ATIS.

That's what we used to get paid the big bucks for.

Of course, these days, we get paid for following the procedures and using the book phraseology. Awareness of what might be useful or important to the flight crew seems no longer required. Perhaps even discouraged.

The former approach helps me sleep better at nights.

As a low hours GA pilot flying various aircraft, all wind info is not only useful but needed as it's my call whether to go ahead and land (when cleared) or last min go around/divert.

Shouldn't be a last min decision as hopefully pilots will have been listening in to ATC calls to other aircraft and know their POH limitations and more importantly their own as pilots.

You don't say the heading of the runway in use so unless it is at/near 90 degrees to the wind the crosswind limit may not be a problem.

I think the key here is that it is always the pilot's decision, based on the best information available to him/her, so there should be no attempts to second guess that decision by witholding information. Knowing how gusty the wind is may result in other decisions taking place that you are not aware of - such as flap settings or which pilot performs the landing.

Provide the pilot with the best available information and leave him/her to make decisions.

Most wind systems in use in the UK won't even display a gust until it reaches ten knots from the mean so it wouldn't even be known about until it happens.
