EASA requirements for offshore operation of aircraft need the installation of an AD-ELT. SPAES has the available EASA STC. The emergency transmitter can be installed at the lower or middle fuselage of the helicopter.
The following devices are installed with the AD-ELT:
- Beacon and Beacon Release Unit on the lower fuselage of the airframe
- Cockpit Control Panel in the center panel of the cockpit
- Water Activated Switch on the bottom of the lower fuselage
