> The vast majority of costs associated with aviation are in maintenance, with the majority of those costs coming from engine overhauls. This is it right here; the CEO of Harbor Air is on record as saying that this is exactly where they expect the biggest costs savings (millions of dollars per year based on their flight numbers) to come from: ——- There would be savings on fuel costs, of course, carbon taxes, and the carbon offsets that Harbour Air buys. But the real savings would be in maintenance. With electric motors, there's next to no maintenance required, whereas with turboprop engines have significant maintenance and rebuild requirements. "You have a motor with a notional life of 10,000 hours – and that's probably being pessimistic – because it's so simple," McDougall said. "We're looking at, in rough numbers, the same 10,000 hours in a conventional turbine will cost a couple million bucks in maintenance, rebuilds and all the rest of it, whereas 10,000 hours in an electric motor should cost us virtually nothing." ——- https://www.piquenewsmagazine.com/bc-news/harbour-air-conducts-first-test-flight-of-all-electric-seaplane-2508937 https://www.piquenewsmagazine.com/bc-news/harbour-air-conduc...
