Plain-English Explainer
ASTM F2840-26A is the active practice covering minimum requirements for electric engines used in light-sport aircraft in VFR operations.
ASTM describes the electrical propulsion system as including the electric engine, controllers, disconnects, wiring and monitoring gauges/meters.
The standard is intentionally narrow: light-sport aircraft and VFR use. PropulsionWatch includes it because it shows how consensus standards are becoming more specific around electric propulsion, but it should not be generalized to all certified electric aircraft.
