The AVMM ELT-S 406 is an aeronautical survival beacon designed for liferafts.

This new generation of ELT complies with the latest regulation and offers all the improvements of the COSPAS-SARSAT system with the 406 MHz frequency :
- Global coverage
- Precise pinpointing
- Identification of the aircraft in distress (the ELT transmits a unique aircraft identification number)
- Efficient process of false alarms to avoid costly search and rescue operation.

The AVMM ELT-S 406 transmits on all 3 emergency frequencies (121.5/243.0 and 406 MHz). The ELT is manually activated during a crash and transmits the standard swept tone on 121.5 and 243.0 MHz. Every 50 seconds for 440 milliseconds the 406.025 MHz transmitter turns on and transmits an encoded digital message to satellite system. The ELT AVMM ELT-S 406 is programmed with either the aircraft tail number, a serial number or the aircraft operator designator. This operation takes only a few seconds.
