This variant, a derivative engine from the Arrius 2, which has proven its durability and reliability worldwide, has been certified in November 2011. As such, it fully complies with the latest and current world-regulation for public transport where in case of one engine is inoperative the remaining engine enables to fly the helicopter. To address the requirement of public transport, the Arrius 2G1, among other specific devices, is equipped with a FADEC controlling the power delivery to the helicopter.

The system implies a "hands-off system" to allow the captain to almost ignore the power-pack when the pilot’s attention is fully involved with cautious piloting when taking-off or landing on/from confined areas (helipad), top-buildings (general hospitals) or access downtown cities for rescue assistance (parking lot and motorway landings).

Furthermore, the engine is also equipped with a power turbine over-speed protection system, which is a response to the regulation requirement. The Arrius 2G1 engine has been tailored to perfectly fit the power pack flying the Kamov Ka-226T, the Russian twin-engine helicopter with double counter-rotating rotor.
