Care must be taken if you are going to 'practice' any sort of rescue signal that there is no possibility of them being mistaken for a 'real' signal.
Under no circumstances should the emergency services have to respond to a 'non-emergency'. This could ultimately cost lives.

Sending and Receiving Signals
These are commonly used body signals that will be understood by airmen. Make sure that all signals are made clearly, exaggerate the movements and use a cloth to make the yes and no signals clear.
A pilot receiving messages from the ground will acknowledge receipt of these messages by:
Message received and understood
In daylight: flying the plane and tipping the wings in a rocking motion from side to side
At night: flashing green lights
Message received but NOT understood
In daylight: flying the plane in a right-handed circle
At night: flashing red lights
These are internationally recognized by all mountain rescue services.
