GLF4LargeEstimateGulfstream IV (G-IV), heavy jet de longo alcance.
Jet Tracker estimate: about US$ 8,873 per flight hour at 400 h/year, of which US$ 6,870 per hour is variable cost (fuel, engine program, maintenance reserves, fees) plus US$ 801,000 per year of fixed cost (crew, hangar, insurance, training).
About US$ 3,549,132 per year (roughly R$ 18.171.557 at today's exchange rate), of which 77% is variable cost (depends on hours flown) and 23% is fixed cost (exists even with the aircraft parked).
About US$ 3,185 per flight hour, at the US$ 5.90 per gallon used in this simulation. Fuel is usually the largest variable cost item.
About US$ 19.33 per nautical mile, at a cruise speed of 459 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.

Crew includes PIC + SIC + benefits; other lines per spec §6.
