Frequently asked questions about the cost
How much does it cost to operate the Beechcraft King Air C90GT per hour?
Jet Tracker estimate: about US$ 2,808 per flight hour at 200 h/year, of which US$ 1,380 per hour is variable cost (fuel, engine program, maintenance reserves, fees) plus US$ 285,500 per year of fixed cost (crew, hangar, insurance, training).
How much does it cost per year to keep the Beechcraft King Air C90GT flying 200 hours?
About US$ 561,577 per year (roughly R$ 3,098,784 at today's exchange rate), of which 49% is variable cost (depends on hours flown) and 51% is fixed cost (exists even with the aircraft parked).
How much fuel does the Beechcraft King Air C90GT burn per hour, in cost?
About US$ 687 per flight hour, at the US$ 6.67 per gallon used in this simulation. Fuel is usually the largest variable cost item.
How much does the Beechcraft King Air C90GT cost per nautical mile?
About US$ 10.32 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.
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.
