So if we have plus or minus 30 knots of windshear in the UK then this would not be reported as it might stop me making an approach. That is exactly why I would like to know!
Such a commercially orientated agreement (which deliberately withholds vital safety information) would result in a H&S Executive prosecution and criminal negligence charges if it led to an accident. No wonder it has not been formalised...do the CAA know about this?Talk about links in the accident chain. Shame we can't bolt some of these management types on a rocky flight into AMS (windshear capital of Europe).
Manchester certainly don't deliberately withold this information ...if it causes a delay (and prevents a stick shaker operating or flap limit speed being exceeded) then the team has worked together to avoid a dangerous situation.
