What is a realistic utilization target?
For rental and training fleets, 50 hours per aircraft per month is steady, 70 is well-run, and 90+ means a busy school with tight scheduling. Partnerships and clubs run lower by design - the target that matters is the one that covers your fixed costs with margin.
Where do the extra hours come from?
Mostly from friction, not demand. Airplanes sit because bookings clash, squawks linger ungrounded or unclear, members cannot see availability, and no-shows go unnoticed. Removing scheduling friction routinely buys hours without a single new customer.
Does more utilization just mean more wear?
Flying costs money per hour - fuel and reserves - but fixed costs do not change. As long as your rate clears your hourly operating cost, every added hour contributes margin, and funded reserves mean the engine overhaul is already paid for when it comes.
