EXTRA 330LX

909.1 GENERAL

To improve the passive security, the EXTRA 330LX can be equipped with an optional Emergency

Locator Transmitter ARTEX ME-406.

In the event of a crash, the ME-406 activates automatically (automatic fixed „AF“ configuration), and

transmits the standard swept tone on 121.5 MHz lasting until battery power is gone. This 121.5 MHz

signal is mainly used to pinpoint the beacon during search and rescue operations. In addition, for

the first 24 hours of operation, a 406 MHz signal is transmitted at 50-second intervals. This

transmission lasts 440 ms and contains identification data programmed into the beacon and is

received by Cospas-Sarsat satellites. The transmitted data is referenced in a database (maintained

by the national authority responsible for ELT registration) and used to identify the beacon and owner.

When the ELT is activated, the buzzer ‘beeps’ and the panel LED pulses periodically. The time

between pulses lengthen after a predetermined transmitter ‘on’ time.

N O T E

In October 2000 the International Cospas-Sarsat Program, announced at its 25th Council

Session held in London, UK that it plans to terminate satellite processing of distress signals

from 121.5 and 243 MHz emergency beacons on February 1, 2009.

Accuracy

Doppler positioning is employed using both 121.5 MHz and 406 MHz signals. Position accuracy

of the 121.5 MHz signal is within an area of approximately 15-20 km radius about the transmitter.

Due to the better signal integrity of the 406 MHz, its location accuracy is within about a 3 km radius.

909.2 LIMITATIONS

The operation limitations are not effected due to the installation of the ARTEX ME-406 ELT.

For the location and operation of the transmitter the following placards have to be attached to the

aircraft:

(outside on the left fuselage in the vicinity of the ELT unit)

(next to the ELT remote switch)

(as close to the ELT remote switch as practical)
