Training Aircraft Manufacturer Bye Aerospace Advances Prototype and Highlights Orderbook in 2025

United States –Bye Aerospace continues to advance its eFlyer electric aircraft programme, with a clear strategic focus on the two-seat eFlyer 2 and the four-seat eFlyer 4 models—setting aside earlier plans for the larger nine-seat eFlyer 800.

• At EAA AirVenture Oshkosh 2025, Bye displayed a non‑flying full‑scale mockup of the eFlyer 2, built using production tools but not flight‑compliant components.
• The company aims to fly a largely production‑conforming prototype within 9–12 months, followed by FAA Part 23 certification approximately 24 months later.
• Bye Aerospace holds roughly 1,024 orders valued at over USD 700 million, with around half backed by non‑refundable deposits and the remainder by letters of intent.
• The eFlyer 2 is powered by a 100 kW Safran EngineUs 100 B‑1 motor with pending FAA validation, paired with Garmin G500 TXi avionics. It features spin‑resistant aerodynamics and includes a whole‑aircraft parachute for added safety.
• Estimated performance: top speed ~135 kt; climb rate ~1,000 fpm; endurance ~3 hrs; range ~220–250 nm; max takeoff weight ~2,450 lb.
• Serial #00001 prototype parts—including the composite wing spar—are already under production in Denver, with full assembly underway. Partner firms such as Elevation Aero, Toray, Siemens, and M4 Engineering support composite build‑out.
