ELT ? Should it be certified as a ELT? It’s a question and it’s a topic for discussion as to wether options like this SHOULD be available.
An Apple Watch only communicates via Cellular and WiFi. This does not meet the requirements for an ELT to broadcast on the 121.5 or 406 MHz SAR frequencies.
Note that per FAR 14 CFR 91.207, "approved" ELT's are required by all U.S. Civil Registered Airplanes with more than 1 seat. Approved means manufactured to TSO-C91A requirements.
