Should "Helivac" be initiated:

Inform other pilots of the eminent arrival of the helicopter - for this: marked the ground with the letter "H" made from wings or other material.

Initially this does not need to be in the proximity of the casualty - this signal is the recognised way of informing pilots (other than using radios).

Upon seeing this sign all pilots should attend to land immediately!

 

When the situation allows the landing site can be marked with the letter "H":

   - 1) Place the H marking at least 15 to 20 m away from a possible touchdown point (see below).
            The H sign is used by the pilots to find the landing zone.
            The actual touchdown point is selected by the pilot.
   - 2) Secure or remove the marking to prevent it being blown about by the downdraft.
            Piling rocks on the marking is not adequate.
            Once the pilot is aware of the landing site; it is better to bunch-up the wings.

- 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:

   - Wind
        Direction and strength, it is worth passing this information to the crew.
        Remember that 'wind direction' is the direction the wind comes from.
   - Size
        Ideally as big as a football pitch but may be as small as a tennis court.
   - Surroundings
        Ideally, no wires, pylons, trees or buildings - including on the approach or overshoot.
   - Surfaces
        The landing surface should be firm. Check for loose articles including personal kit and clothing.
   - Slope
        As level as possible.

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).
