eDA40 Eyed For Training Duties With Lufthansa Aviation Training JF doesn't normally cover Piston aviation as this is a Jet and turboprop Forum. The Diamond DA40 would normally be Piston related but the eDA40 is fully-electric. In the realm of flight training, Diamond Aircraft Austria and Lufthansa Aviation Training (LAT) have signed a Letter of Intent (LOI). The LOI covers an eDA40 purchase intention to supplement the current regular DA40 NG fleet as well as analyses for the use of Sustainable Aviation Fuels (SAF) for the regular fleet. Diamond Aircraft introduced the eDA40 to the market in October 2021. It will be the first EASA/FAA Part 23 certified electric airplane with DC fast charging, capable of turning around a depleted aircraft in under 20 minutes. Flight times are expected to improve to around 90 minutes as battery technology improves.
