It seems with electric control of the multi engine configuration, such as with NASA's new leap tech technology, that there should be a way to use multiple motors in the LSA category. Is there anything in the works regarding regulations for this type of aircraft in the LSA category?

  • $\begingroup$ Last I read, the FAA hadn't made provision for manned electric aircraft of any type. It's possible that multi-rotor electric designs would constitute a new class (or even multiple new classes) of aircraft. It's probable that such a concept will (or won't) be proven in the experimental aircraft community. If it represents a viable model for commercial development, external pressure would force the FAA to acknowledge, and regulate it. $\endgroup$ – Dennis Wolfers Sep 13 '15 at 20:12
  • $\begingroup$ At least in the US, LSA certification is the purview of ASTM F37. They don't seem to have a subcommittee dedicated to multi-motor anything, and I didn't dig deeply enough to see whether the existing committee has any standards for single-engine electric LSAs. $\endgroup$ – paulr Apr 29 '16 at 20:26
  • $\begingroup$ As for Europe, currently the issue is not considered. Currently multi engine configurations do have certification advantages as an engine failure is not seen as critical as for single/double engine configurations. $\endgroup$ – Lumis Mar 5 at 9:32
