Definition
A rate is built in three layers, and skipping the second is the usual cause of a fleet that looks busy and earns nothing.
**Layer one is direct operating cost per hour**: fuel, oil, and the hourly accruals for engine, propeller and scheduled and unscheduled maintenance. These are incurred because the aircraft flew. They form the floor below which an hour actively loses money.
**Layer two is fixed cost recovery**: hangarage, insurance, financing or the capital tied up in the airframe, the calendar portion of the annual inspection, subscriptions and airworthiness review fees. These accrue whether or not the aircraft moves, so recovering them per hour means dividing an annual total by the hours the aircraft is expected to fly. This is where the arithmetic turns on an assumption rather than a measurement, and where rates go wrong.
**Layer three is margin**, plus whatever the market will bear. A rate that covers layers one and two exactly is a break-even rate, not a business.
The consequence of layer two is that a rate is only valid at an assumed utilisation. Take an aircraft with $48,000 of annual fixed cost and $95 an hour of direct operating cost. Planned at 400 hours a year, fixed recovery is $120 an hour and the break-even rate is $215. The same aircraft flying 260 hours carries $185 an hour of fixed cost and needs $280 to break even. A school that set $215 and delivered 260 hours is losing roughly $65 on every hour it flies, while the rate card, the invoices and the bank balance all look ordinary until the year closes.
The second structural decision is what the rate includes. A **wet rate** bundles fuel; a **dry rate** does not, and exposes the school to fuel price movement differently. Whether instructor time is inside the rate or billed as a separate line changes both the headline number a prospective student compares and the clarity of the school's own margin analysis — a blended rate makes it hard to tell whether aircraft or instruction is carrying the business.
Rates also need a review cadence. Fuel, insurance and maintenance labour all move; a rate set once and carried for three years is a slow margin leak that nobody has to decide on for it to happen.
Why It Matters for Flight Schools
For an owner, the discipline is to re-derive rates against measured utilisation rather than the utilisation the fleet plan assumed. The assumption is usually made once, at purchase or at budget, and then quietly outlived by reality.
The most common error is benchmarking against a competitor's rate card without knowing their utilisation, their fixed-cost base or what their rate includes. A neighbouring school charging $30 an hour less may be flying the same type 500 hours a year against your 280, in which case matching their rate is matching an outcome you have no route to.
The second error is treating a rate rise as purely a demand question. If the rate is below break-even at current utilisation, every additional hour flown deepens the loss, and filling the schedule makes the problem worse rather than better.
How Aviatize Handles This
Aviatize uses a versatile rate-setting system with separate line items for aircraft cost, instructor cost and any extra charges, so a school can price the aircraft and the instruction independently and see each on the invoice rather than inside one blended figure. Rates can be set per aircraft, and contracts can carry either the standard school rates or custom rates specific to that contract.
Because bookings, flights, invoices and maintenance records sit on the same record, utilisation per aircraft is measured from the hours actually flown rather than assumed from a fleet plan — which is the denominator the fixed-cost half of a rate depends on. A school can therefore check a rate against the hours the tail really achieved, and compare tails across the fleet or across locations.
Frequently Asked Questions
- How do you set an hourly rate for a flight school aircraft?
- Start with direct operating cost per hour — fuel, oil and maintenance accruals — then add fixed cost divided by the hours the aircraft is realistically expected to fly in a year, then add margin. The middle step is what makes a rate valid only at an assumed utilisation: the same aircraft needs a materially higher rate at 260 hours a year than at 400.
- Why is our aircraft rate not covering its costs?
- Most often because the rate was built on planned utilisation that the aircraft never reached. Fixed costs do not fall when hours do, so each hour flown has to carry a larger share of them. An aircraft priced for 400 hours a year and flying 260 can be losing money on every hour while the rate card looks unchanged and the schedule looks busy.
- Should a flight school use a wet rate or a dry rate?
- A wet rate includes fuel and gives the student a predictable number while leaving the school exposed to fuel price movement. A dry rate excludes fuel and shifts that exposure. Neither is inherently better, but comparing your rate to another school's is meaningless unless you know which convention each uses and whether instructor time is bundled in.
- How often should flight school rates be reviewed?
- Often enough to track the inputs that move: fuel, insurance renewals, maintenance labour rates and actual utilisation. A rate carried unchanged for several years erodes margin without anyone making a decision, because the costs underneath it moved while the number did not.
