Emergency Locator Transmitter
Emergency Locator Transmitter (ELT) or Personal Locator Transmitter (PLB).
NOTE: the 15 bit code in ELT’s is different to the 24 bit code the Aircraft Registry issued for the transponder. The ELT maintenance facility, using Registry Publication 13 (RP13), will provide you with the 15 bit code.
The ELT or PLB must be registered with the UK Mission Control Centre (UK MCC). Application Form 37 is available below.
