ELT (Emergency Locator Transmitter)
9.4.1
General
Depending on customer’s configuration or legal requirements the gyroplane can be
equipped with an ELT (Emergency Locator Transmitter) as an option. The ELT sends
distress signals on 406 MHz and 121.5 MHz in case of a crash or can be activated manually
by means of a remote cockpit switch or at the ELT’s front panel. These distress signals are
received and processed by COSPAS-SARSAT satellite-based search and rescue (SAR)
system and by airborne and ground stations. The system is designed to remain permanently
attached to the aircraft.
9.4.2
Limitations
No change to standard aircraft.
9.4.3
Emergency Procedures
In case of the following events, manually activate the ELT by switching the remote cockpit
switch to ‘ON’:
Expected crash landing
Forced landing in hostile terrain (high vegetation, trees, rugged ground)
Ditching in hostile water (sea state, temperature, off-shore)
Consider to squawk ‘7700’, if transponder is installed and to make an emergency call.
When on ground, inform ATC, any nearby tower or any station via 121.5 MHz or mobile
phone about the emergency, if still possible.
9.4.4
Normal Procedures
During normal operation, the front panel switch of the ELT transmitter must be in ‘ARM’
position in order to allow automatic activation (g-sensor). In addition, the ELT can be
activated by switching the remote cockpit switch to ‘ON’. The red visual indicator will be on.
During road transport, shipment, when the aircraft is parked for a longer period or for
maintenance operation, the front panel switch of the ELT should be switched to ‘OFF’ in
order to avoid false alarms.
In case of accidental activation, the ELT can be reset either by switching to ‘RESET/TEST’
on the Remote Control Panel or switching to ‘OFF’ on the ELT transmitter.
