1. Description
SUBTASK 25-69-10-870-001
A. Overview
(1) The ELT/NAV Interface is integrated into the ELT system. See "Figure 1. ELT/NAV Interface
System Integration".
Figure 1. ELT/NAV Interface System Integration
(2) The ELT/NAV Interface is designed to work with “ELT with 24-bit Address” and “ELT with
Serial Number” location protocols. In both cases, the ELT/NAV Interface provides position
coordinates (latitude and longitude) to the ELT.
(a) For aircraft using an “ELT with 24-bit Address” location protocol, the ELT/NAV Interface
also provides the means to reprogram an ELT automatically in the event an ELT
programmed with a different 24-bit address aircraft ID has been placed in the aircraft.
(b) For aircraft using an “ELT with Serial Number” location protocol, the ELT/NAV Interface
reprogramming receptacle (P1) is capped and the unit only provides position data to the
ELT.
