Getting Found and Getting Out: ELTs, Equipment and Egress

Summary

ELTs summon help — 121.5 MHz on older units, 406 MHz digitally on modern ones. Know your emergency equipment, brief passengers on egress, and after landing secure fuel and electrical systems and get everyone clear.

Why this matters in flight

Surviving the landing is only half of an off-airport emergency. Being located quickly and getting everyone safely out of the aircraft afterward are what turn a survivable accident into a survived one.

The emergency locator transmitter (ELT) is your automatic call for help: it transmits a distress signal after a crash to guide search and rescue. Older ELTs transmit on 121.5 MHz, while modern 406 MHz units send a digital signal to satellites with far better location accuracy and aircraft identification. It is good practice to monitor 121.5 when able, and to confirm after a hard landing that the ELT was not set off by accident. Equally important is preparation for egress. Before flight the pilot should know where the emergency equipment is and how to use it — fire extinguisher, first-aid kit, survival gear, and life vests over water — and brief passengers on seatbelts, the doors, and how to get out. After an off-airport landing, the sequence is to stop the aircraft, shut down the fuel and electrical systems to reduce the fire risk, and get everyone clear of the wreckage. Planning these actions in advance means they happen automatically when they matter most.
