  • How the overhaul will be paid for (reserve, financing or cash) and when the money is needed.
  • Overhaul, exchange or a factory engine: what each costs, and how long the aircraft would be down.

Ideas, not recommendations. Your situation may differ.

In the forecast, revenue there is expected at about 61% of an average month, and N744PS's engine overhaul ($84,000) falls in it, leaving about $82,230 more going out than coming in.

Ideas schools in this spot often explore

  • When the large cost has to be paid: a deposit, payment terms, or financing that spreads it over several months.
  • What brings in revenue in the slow months: ground school, simulator time, or block-time packages sold ahead of winter.
  • Timing maintenance that isn't due yet into the stronger months before or after it.

Ideas, not recommendations. Your situation may differ.

N744PS$12,798 est booked, not flown

It flew about 57% of the time booked, leaving time worth about $12,798 that no one else could book.

Ideas schools in this spot often explore

  • Whether the booking length for these lessons includes briefing time that could be booked separately, so the aircraft is free sooner.
  • How long bookings are blocked for: whether the default block fits the lesson, or leaves time nobody uses.
  • Whether bookings start on time, and what happens to the time when a lesson ends early.

Ideas, not recommendations. Your situation may differ.

Ideas schools in this spot often explore

  • How the cancellation and no-show policy is set: notice period, fees, and whether it's applied consistently.
  • Reminders before each booking, and how easy it is for a student to move a booking instead of dropping it.
  • A standby list that fills cancelled slots at short notice.

N744PS's next inspection falls in the same two weeks as other aircraft's.

N744PS flew 18% of the fleet's hours, and the others are due within days of it, so they could all be down at once.

Ideas schools in this spot often explore

  • Bringing one inspection forward a few days so the aircraft aren't down at the same time.
