ELECTRIC TRAINING AIRCRAFT

The official program launch, and FAA type certificate application for the eFlyer 2 program began in April 2018.  The eFlyer program was created by Bye Aerospace to initially produce the two seat “eFlyer”, and for it to be fully certified under the new FAR 23 Amendment 64, ‘normal category’ and bring it to market worldwide. We intend to serve general aviation initially by providing a clean, renewable energy, electric training aircraft.  Other utilities will follow including pilot-owner, business, charter and regional.  As of mid-2023 we have over $1B in customer backlog value, the majority of the paid purchase deposit split evenly between the eFlyer 2 and eFlyer 4, with many eFlyer 800 customer deposits also.

 

eFlyer 2

 

This two-seat aircraft will change the way pilots train. The cost-efficient aircraft will enable new pilots to train without prohibitive fuel costs.

 

  • eFlyer 2™ was the world’s first FAA 14 CFR Part 23-Type Amendment 64-Certified Applicant for a “Normal Category” Electric Aircraft, (FAA application filed April 13, 2018)
  • The eFlyer design is entirely new, from tip to tail
  • Aerodynamic efficiency is over twice that of a typical legacy aircraft of similar size
  • High overall propulsive system efficiency with high motor efficiency with low cooling drag
