Frequently asked questions about the cost

How much does it cost to operate the Diamond DA40 per hour?

Jet Tracker estimate: about US$ 247 per flight hour at 200 h/year, of which US$ 148 per hour is variable cost (fuel, engine program, maintenance reserves, fees) plus US$ 19,810 per year of fixed cost (crew, hangar, insurance, training).

How much does it cost per year to keep the Diamond DA40 flying 200 hours?

About US$ 49,330 per year (roughly R$ 271,941 at today's exchange rate), of which 60% is variable cost (depends on hours flown) and 40% is fixed cost (exists even with the aircraft parked).

How much fuel does the Diamond DA40 burn per hour, in cost?

About US$ 37 per flight hour, at the US$ 6.20 per gallon used in this simulation (reference price, not today's quote). Fuel is usually the largest variable cost item.

How much does the Diamond DA40 cost per nautical mile?

About US$ 1.60 per nautical mile, at a cruise speed of 154 kt. It is the right metric to compare aircraft of different speeds on the same route.

What is the difference between variable and fixed cost?

Variable cost only exists when the aircraft flies: fuel, engine program, hourly maintenance reserves and landing fees. Fixed cost exists even with the aircraft in the hangar: crew, hangarage, insurance, training and subscriptions. That is why total cost per hour falls the more hours per year the aircraft flies.
