Have you ever wondered how people find missing airplanes? It turns out that they use a thing called an ELT or Emergency Locater Transponder. When triggered, it sends out a distress signal on the frequency of 121.500mhz better know as the emergency frequency. If you have a special receiver, you can hear the ELT, it is a very very creepy siren like noise. It tracks Emergency Responders to the crash site with precise GPS locations. That is what that creepy siren noise is. It is a cool system how the ELTs work. For more info, look here!
Hope you enjoyed this “lesson”!
(By the way I made this topic because we had to train for finding a lost airplane today with the Civil Air Patrol and I thought that I would let you all know some pretty cool stuff about the ELT. Please note that this info is only from the ELT that we trained on.)
