Frequently asked questions about the cost
How much does it cost to operate the Beechcraft King Air C90B per hour?
Jet Tracker estimate: about US$ 2,935 per flight hour at 200 h/year, of which US$ 1,121 per hour is variable cost (fuel, engine program, maintenance reserves, fees) plus US$ 362,900 per year of fixed cost (crew, hangar, insurance, training).
How much does it cost per year to keep the Beechcraft King Air C90B flying 200 hours?
About US$ 587,020 per year (roughly R$ 3,239,176 at today's exchange rate), of which 38% is variable cost (depends on hours flown) and 62% is fixed cost (exists even with the aircraft parked).
How much fuel does the Beechcraft King Air C90B burn per hour, in cost?
About US$ 484 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 Beechcraft King Air C90B cost per nautical mile?
About US$ 12.54 per nautical mile, at a cruise speed of 234 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.
