The value shown is not considered to be limiting.
DFC - so why would the lawyers add this in the POH?
An aircraft I fly is placarded to say I MUST NOT perform certain aerobatics if certain conditions are not met.
I can find no placard to say I MUST not land if the cross wind component is above a certain figure.
Why is there a placard for the first (and I might never fly aeros in the aircraft) but not for the second, given at the very least I am hopefully going to land after every flight.
