For the non-specialists out there: ELT stands for “emergency locator transmitter“, which is a device that is found in many aircraft. It is activated by sudden motion, like in the event of a crash and sends off an emergency radio signal on a specific frequency. Since it’s triggered by jolts and shocks, it sometimes activates on particularly brutal landings, which, in Chuck’s case, maybe happen more frequently than average.
I guess it’s like with smoke alarms. The benefit of safety outweighs having to deal with a certain number of false alarms. Although the truth of that statement also depends on the actual number of false alarms, as anyone who had to replace a smoke detector battery at 3 A.M. will be willing to testify!
