When you’re in the wild and need help, you send out a signal –- basically anything to get noticed. A good signal not only gets the attention of search-and-rescue teams but also of people not looking for you — passersby who can help before professionals arrive. The following methods show you how to get people’s attention with signals.
Ground-to-air emergency code
These symbols are recognized by Search and Rescue pilots as distress signals. Make sure you make these signals a 6:1 ratio so rescuers can see them from the air.
Aiming reflector
You must carefully aim your mirror’s reflection at the aircraft or vessel you wish to signal, or you may not be seen. You can use a mirror or other reflective items, such as a CD or DVD.
