In an emergency situation, how should I signal for help using the Jet Scream Whistle?
A. The Jet Scream Whistle is most useful in signalling to a ground-based search party. In this situation, an internationally recognised symbol of distress is a series of three (3) signals (blasts of the whistle). Ground search parties will generally give three signals followed by a period of silence to listen for a response. Signal to the search party during the silence and continue to do so to assist them in locating your position.
