Full operating cost, variable vs fixed mix and a line by line breakdown: the math that decides the purchase.
Starter feature. Available on your Jet Tracker account.
Jet Tracker estimate: about US$ 1,906 per flight hour at 400 h/year, of which US$ 1,259 per hour is variable cost (fuel, engine program, maintenance reserves, fees) plus US$ 258,600 per year of fixed cost (crew, hangar, insurance, training).
About US$ 762,334 per year (roughly R$ 3,851,617 at today's exchange rate), of which 66% is variable cost (depends on hours flown) and 34% is fixed cost (exists even with the aircraft parked).
About US$ 514 per flight hour, at the US$ 6.12 per gallon used in this simulation. Fuel is usually the largest variable cost item.
About US$ 7.01 per nautical mile, at a cruise speed of 272 kt. It is the right metric to compare aircraft of different speeds on the same route.
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.
