This is about replacing a turboprop with a slightly smaller turboprop and electric motor/generator+battery. The turboprop burns Jet-A, not leaded aviation gasoline.
replyIf you care about leaded fuel, the culprit now is general aviation - small airports, Cessnas, not commercial flights. If you go work on it, let me know, I'll help you!
replyDont we have approved fuel replacement for leaded fuel now finally ?
replyAlso I swear there was a company replacing a push pull type plane with a hybrid ?
