Artex ELT to NAV Interface is designed to be connected between the aircraft's flight management computer (FMC) or GPS receiver and Artex's 406 MHz series of ELT's. Its function is to receive continuous position updates from the aircraft's navigation system and translate it to the proper format for use by the ELT. Upon activation, the ELT transmits the latitude and longitude of the aircraft to the COSPAS/SARSAT satellite system. Knowledge of the position information allows SAR forces to launch an immediate mission to the last known position of the aircraft.

Use of this technology provides the following information to Sar teams:

1) Type of aircraft
2) Owner(s)
3) Emergency contact(s)
4) Country code
5) Serial number of ELT
6) ELT manufacturer
7) Latitude/longitude position

Another advanced feature of the interface is an ability to custom program the ELT to the 24-bit address assigned to commercial aircraft and used by the TCAS system. This is extremely useful for fleet operators who may find it necessary to change ELT’s in aircraft for maintenance purposes because it eliminates the need to reprogram the ELT every time it is moved.

The Artex ELT to NAV interface works with 28V aircraft systems only.
