- Wind Direction Indicators:
If possible use a small wind sock, streamer or rag tied to the end of a stick, or at arm-length, in the vicinity of the landing area, to help
the helicopter pilot to judge wind direction at the landing site.
- Hand Signal:
Wind direction can also be indicated by someone standing (upwind edge of the site)
- at least some 20m from where the helico will be landing
- with his back to the wind and his arms extended forward.
- Helicopter Landing Sites:
If ground parties are selecting or preparing a site, they should consider:
Direction and strength, it is worth passing this information to the crew.
Remember that 'wind direction' is the direction the wind comes from.
Ideally as big as a football pitch but may be as small as a tennis court.
Ideally, no wires, pylons, trees or buildings - including on the approach or overshoot.
The landing surface should be firm. Check for loose articles including personal kit and clothing.
As level as possible.
- Help the Pilot:
Should the helicopter overfly to find the casualty signal that you are or not the point of action using the following signals:
For NO - facing the helico: raise your right arm (45°) and lower your left arm (45°) [simulating the cross stroke of a N] - stay still - do not wave!
(If you wave you may be taken for a 'tourist' saying hello!)
For YES - facing the helico: raise both arms (45°) [forming a Y with your body] - stay still - do not wave!
(Once you have ascertained the pilot knows the correct location - convert to Wind Direction Indicator).
