Random Ramblings: Aerial Wildland Firefighting

I have blogged about aerial wildland firefighting since 2009. I am not a firefighter and am not a pilot, just an interested bystander who wants to learn more and share what I learn here. Join me here as I blog on the aircraft and the pilots who fight wildland fires from the air in support of crews on the ground. I also blog on concerns affecting fire crews on the ground as well as other aviation and meteorology issues. Learn what it takes to do jobs that are staffed by the best of the best.

Part 3 of 8: Cessna Annual 172P - Emergency Locator Transmitter Service

I watched the service of the Emergency Locator Transmitter (ELT). I learned that the batteries are replaced after 1 hour of cumulative use or after 50% of their service life is expired. The ELT is designed to activate and transmit a signal after being subject to forces generated in a crash. I understand that the ELT is in different locations in different airplanes.
