(PDF-1 contains short/long flag and the 15-Hex ID number) • Decoded protocol information from the short/long format data, including: — Protocol used (e.g. ELT serial user protocol, ELT national location protocol) — Country — Type of auxiliary radio locator — Identification data (e.g. aircraft registration, 24-bit address, call sign, etc, depending on mode) |
