The Deadman's Curve is a technical and somewhat notional consideration.
It is based on pilots reaction to engine failure and it is reduced with a headwind and it's relative W/V......so the variables are many. This in turn reduces the risk exposure of the helicopter if constantly considered by the pilot operating in or near the RFM's H/V charts! The JAA OPS alludes to it by percentage of wind component and distance to attain a certain height above a given obstacle. Try
