Many,many times I have diverted to PXO,or LIS due to the strong winds in FNC,and still when I arrive there to my surprise,only the British Charters have operated normally(You can not say either the Portuguese or German Airlines are different!!!)
It is well known that sometimes there is a "calm" in the wind intensity that allows 1 or 2 planes to land or take-off...it has been so for years,and so it will continue.
Actually TAP Air Portugal is very critisised in Madeira for not operating many times while the Charters are landing and taking off as they please...please do not see this as a critic,as I quite know that in FNC is a "difficult" operation,and winds can be quite unpredictable.
