Quick Answer
To use an emergency beacon after a plane crash, locate the Personal Locator Beacon (PLB) or Emergency Position-Indicating Radio Beacon (EPIRB) within the wreckage, press the activation button, and follow the voice prompts or instructions on the device.
Activating the Emergency Beacon
Locate the PLB or EPIRB in the wreckage as soon as possible, ideally within 15 minutes of the crash. These devices are often attached to the aircraft’s emergency kit or stored in a designated compartment. Check the device for any damage or water exposure before attempting to activate it. If the device is damaged or waterlogged, do not attempt to activate it.
Signaling for Help
Once the PLB or EPIRB is activated, you will be assigned a unique distress frequency and a corresponding signal for rescue teams to locate you. The beacon will typically transmit a signal on a frequency of 406 MHz, which will be received by satellites and relayed to emergency responders. If you are in a remote location, use visual signals such as a fire, flares, or a brightly colored parachute to signal for help during the day. At night, use flashlights or other light sources to signal your location.
Shelter and Safety
Take immediate action to ensure your safety and shelter in the aftermath of the crash. Ration any available food and water, and find or create a shelter to protect yourself from the elements. The wreckage itself may provide some protection, but you should also gather any available materials to construct a more secure shelter. This could include branches, leaves, or other natural materials to create a makeshift lean-to or debris hut. Use the PLB or EPIRB activation as a signal to rescue teams, and remain in your shelter until help arrives.
