Never heard of a legal limit for wind speed in absolute terms
All A/C I have flown have had a max wind for Taxi limit. Little point in battling the A/C onto the deck with max crosswind limit only to not be able to taxi to stand.
Other than that we operate as per AVCP, although our Ops manual makes no reference to wind speeds when planning which surprises me.
Example:
METAR GCLA 061600Z 23025G40KT 170V280 7000 -DZ FEW025 SCT045 BKN180 23/10 Q1003=
What's the relevant crosswind on runway 19 at La Palma (centreline about 180 true, I think)?
Can't help with the actual legal view on this but I'd assume (for planning purposes) worst case 40kts from 270, ie all crosswind, especially as wind veers in gusts... which for my A/C means steady wind near limit and gusts out of limits. Now according to JAR thats OK but I personally would be looking to have a more usable alternate or 2 up my sleeve and plan and fuel accordingly.
