CTD asks what charts I referred to with the Bell line that publish hover capability with and without adequate crosswind capability.
I have seen copies of these charts for the Bell 212, 412, and 430. Specifically, they are the family of hover charts for hover (IGE and OGE) weight vs altitude/temperature that are titled "wind from any direction" and "wind within 45 degrees of the nose". The no-crosswind (wind from the nose) charts are also labeled (at the bottom, in small print) "Catagory B, 9 passengers or less". For the IGE and OGE cases, with the two wind cases, there are a total of four charts for each model helicopter.
This capability was brought about to allow operations at higher weights and powers with scant tail rotor capability as long as the pilot could operate with no cross wind (and with high hopes that there would be no need to raise the collective very much while hovering).
The charts are specifically for Cat B, 9 passengers or less operations, and should be available as flight manual supplements if you ask.
Bell used to have PDF files at their web site that had these charts, but they are not posted there now.
