max DEMONSTRATED crosswind is exactly that, max crosswind component the aircraft was demonstrated to land in during certification.
It appears that Crosswind maximum is a grey area, some think its a hard limit not to exceeded ever, and others, like myself, see it as above, max demonstrated, and crosswinds that are higher can be handled by the aircraft.
Ditto!
Depends on the experience of the pilot and their demonstrated abilities.
Remembering that this is a GA forum - I have landed the V-tail in conditions well above its maximum demonstrated X-wind of 17 kts, ie 25 kts gusting to 30 kts all x-wind. The end result was one flat-spotted tyre, but it was close to its use by date and a small price to pay for being safely on the ground in rapidly deteriorating conditions that I was not keen to climb back into.
And if I had pranged it - well that's what insurance is for isn't it?
