  approach path that will serve as go/no-go points should the pilot feel any assessed parameter is being exceeded. Wind direction and velocity are assessed as a medium risk because (for this scenario) the direction of the wind is slightly offset ... crosswind with a steady 10-knot wind. The pilot also takes into consideration that, due to the terrain, the wind direction and velocity may change during the approach. The pilot’s experience and awareness of the complexity of mountain flow…

  helicopter approaches the scene, it will normally orbit at least one time as the flight crew observes the wind direction and obstacles that could interfere with the landing. This is often referred to as the “high reconnaissance” maneuver. f. Wind ... Direction and Touchdown Area 1. Determine from which direction the wind is blowing. Helicopters normally land and takeoff into the wind. 2. If contact can be established with the pilot, either directly or indirectly through the HEMS ground communications specialist…

Information may also be provided by FSS personnel either located ... receive and broadcast on this frequency. When none of these services is available, it is possible to determine wind direction and runway in use by visual wind indicators.
