Aircraft utilization reports for flight schools

Three numbers, not one

For every aircraft, over the same window, you want:

Booked hours

What the schedule promised. This is demand — and the number a busy-looking calendar reflects.

Flown hours

What actually happened, from Hobbs at close-out. This is delivery.

Billed hours

What made it onto an invoice. This is revenue.

Gap one: booked but not flown

The distance between booked and flown is your efficiency. A school running 400 booked hours and 256 flown is at 64% — and the other 36% is weather, cancellations, no-shows, and maintenance pulling a tail off the line. You cannot fix that number without knowing which of those four it is, which is what a cancellations report broken down by reason is for.

This gap also distorts planning. Schools size their fleet against booked demand, then wonder why the extra aircraft did not pay for itself.

Gap two: flown but not billed

This one is pure leakage. The aircraft flew, fuel was burned, an instructor was paid — and no invoice exists. It usually comes from flights that were never closed out, so the hours were never known. It is invisible on a calendar and invisible in a bank statement, because you cannot miss money you never billed.

AerScheduler puts this on the dashboard as a flown, not invoiced count and an awaiting close-out count, both of which open into the exact list of flights so someone can fix them the same week rather than discovering them at month-end.

Then rank tails by what they earn

Hours are a proxy. Revenue is the answer. Grouping revenue by aircraft tells you which tail earns its insurance and hangar space, which is the conversation you want before renewing a lease or buying another 172.

• Booked, flown, and billed hours per aircraft, side by side
• Efficiency as a single percentage you can trend month over month
• Billed, collected, and outstanding revenue grouped by tail
• Downtime from squawks, so a low performer's excuse is visible too
• Any window you like, exported to CSV when the board wants a copy

Where this lives in AerScheduler

The Utilization and Fleet reports carry these numbers, and both are reachable from the dashboard — pin a utilization tile for the fleet and a second one filtered to a single aircraft, each with its own date range. See reports and dashboards for how that fits together, or fleet management for where the rates and Hobbs readings come from.

FAQ

What is aircraft utilization at a flight school?

Utilization is how much of an aircraft's available time is actually earning. In practice you need three numbers per tail over the same window: hours booked, hours flown, and hours billed. Hours flown alone tells you the airplane moved, not whether the school got paid for it.

What is a good utilization rate for a training aircraft?

It varies with fleet size, climate, and whether the aircraft is a primary trainer or a complex type, so a single benchmark is misleading. The number that matters more is your own trend: whether efficiency — flown hours as a share of booked hours — is improving month over month, and whether any one tail is drifting away from the rest of the fleet.

Why are my booked hours higher than my flown hours?

Cancellations, no-shows, weather, and maintenance. A persistent gap means your schedule is optimistic and your fleet looks busier than it earns. AerScheduler reports the gap directly as an efficiency figure per aircraft, and the cancellations report breaks down the reasons.

How do I find flights that were flown but never invoiced?

Compare flown hours against billed hours. Where flown exceeds billed, flying happened that nobody charged for. AerScheduler surfaces this as a 'flown, not invoiced' count on the dashboard that opens straight into the list of affected flights.

Can I see revenue per aircraft?

Yes. AerScheduler reports billed, collected, and outstanding revenue grouped by aircraft, so you can rank tails by what they actually earn rather than by how often they appear on the schedule.
