■ GROUND TO AIR EMERGENCY SIGNAL CODE
Nine basic ground to air emergency signal codes are inscribed on the dial. They are to be used to
communicate with rescue aircraft from the ground in case of distress.
How to use the ground to air emergency signal codes
In case of distress, describe the ground to air emergency signal codes on the ground so that the search
aircraft or rescue party can easily recognize them. Each letter should be at least 10 m2 in size with its top
and bottom facing the directions of south and north, respectively. When describing the code on a field of
snow, dig a ditch or pile up snow in the form of the letter so that it can be discerned by the shade. If the
victim is weakened and does not have enough physical strength to describe the codes on the ground, use
clothes or equipments to form the letters. Grass, branches of trees or stones can also serve this purpose.
In rescue operations, the rescue aircraft uses a loudspeaker or a communication tube to send messages
to the victim, but it is difficult for the victim to respond to the rescuer. The ground to air emergency signal
codes will facilitate communication between them and help rescue operations progress smoothly.
