A very interesting question on wording in the flight manual.
Aside from the Bulletins on the R-22, most older flight manuals will have wording in the limitations section to the effect of 'the helicopter has been demonstrated in winds of 17 knots from all directions'.
Does this really sound like a limitation? What does it mean?
It means that the certification criteria, namely to be able to have adequate control margin to hover with winds of 17 knots from any direction, has been demonstrated at the weight and density altitude limitations for takeoff and landing shown in the flight manual. Nothing more.
You may be able to handle higher winds at lighter weights and lower density altitudes, but there's no guarantee.
A case of a something in the limitations section not really being a limit....
