Inside the cockpit.
Every G1 includes the Exentra Flight System (EFS) — combining EFS Flight, the iPad cockpit app with synthetic vision and active safety, with EFS Companion, the mobile app from preparation to post-flight management. Beyond our tailored flight system, two cockpit packages let you decide how deep you want to fly informed.

The Pro package can be extended with the Sensor + Cloud Connect Package (LIDAR, dual-camera, Starlink Mini, atmospheric sensor) and the Autopilot System (four servos with integration kit) — assemble it in the configurator.
Active safety systems.
EFS Flight is Exentra's in-cockpit flight intelligence, layered on top of the trusted primary instruments. With the Pro package, synthetic vision combines AI-analyzed dual-camera detection, LIDAR ground sensing, and real-time airspace data into one intuitive display and automatically highlights nearby aircraft and restricted zones. Always-on connection via our own EFS Cloud keeps the aircraft linked to live data. In critical situations, the system calculates an optimized emergency path to the nearest airfield, while envelope protection and Angle-of-Attack (AoA) sensing — activated with the Autopilot System — actively prevent stalls before they occur.

Everything around flying simplified.

The EFS Companion App connects pilot and aircraft into one seamless experience. Plan your flights, navigate with confidence, and automatically track every journey — all in one intuitive system. From preparation to post-flight management, everything is designed to keep flying simple, organized, and stress-free, so you can focus entirely on the joy of being in the sky.
