Useful numbers before expensive decisions

Independent calculators for aircraft buyers, owners and pilots. Planning support only, never a substitute for approved data.

Aircraft Ownership Cost Calculator

Estimate annual fixed costs, variable costs and the effective cost per flight hour.

Separate fuel, maintenance reserves and fixed overhead to test different utilisation levels.

Calculate trip fuel and cost from fuel burn, flight time, reserve and local fuel price.

Estimate monthly payments, total interest and cash required at closing.

Build a planning range from hull value, pilot experience and aircraft complexity.

Estimate still-air reach after reserve, wind and payload adjustments.

Estimate density altitude from elevation, pressure setting and outside air temperature.

Apply conservative runway, surface, slope and density-altitude adjustments to a baseline figure.

Check payload remaining after pilot, passengers, baggage and usable fuel.

Resolve wind into crosswind and headwind or tailwind components for a selected runway.

Convert nautical miles, kilometres, statute miles, knots, metres and feet.

Numbers need context

The Finder tests acquisition cost, annual spend, seats, payload, runway and range together.
