Our Market

Until the Covid-19 pandemic, demand for new airline pilots around the world had increased dramatically over requirements from 5 or 10 years ago. Due to the coronavirus impact on airline transportation, this demand was temporarily reduced for three years. However, over a longer 20-year timeframe, according to Boeing forecasts, an estimated 649,000 new commercial and airline pilots are needed. This requirement is over 4 times increase of the 165,000 airline pilots flying today.

Due to the age and operating expense of the fleet, the existing 230,000-unit General Aviation fleet is ripe for replacement. The majority of these aircraft were manufactured between 1960 and 1983 when production averaged over 10,000 units per year. Sales slumped in the early 1980’s due to market saturation, rising fuel costs and limited access to capital with high interest rates. According to the FAA and GAMA, in the U.S. there are approximately 11,000 trainers in use today that average 48-years old. These old, legacy aircraft are difficult and costly to maintain, burn expensive leaded aviation gasoline producing CO2, and are nearing obsolescence. With low operating cost and high-performance benefits, the all-electric eFlyer 2 and eFlyer 4 are designed to be ideal pilot trainer replacement aircraft -our initial market focus.
