Time, Fuel & Distance to Climb Calculator
The POH climb-table computation live: minutes, gallons and miles from origin altitude to cruise altitude, with the average-rate method the tables use.
The integration matters: climbing 1,500โ9,500 ft takes notably longer than (8,000 รท sea-level rate) because the rate decays as you go. POH time-fuel-distance tables are built exactly this way โ this is their formula unfrozen.

About Time, Fuel & Distance to Climb Calculator
The climb is the most expensive mile of the flight โ highest fuel flow, lowest speed, hardest cooling โ and the POH's time-fuel-distance table is its invoice. This calculator rebuilds that table's method live: the climb rate decaying linearly toward the ceiling, integrated in 500-foot steps from your start to cruise altitude, returning minutes, gallons and the along-track miles to your top-of-climb point for navlog and fuel planning.

Frequently asked questions
Why can't I just divide altitude gained by my climb rate?+
Because there's no single rate: 700 ft/min at sea level decays toward zero approaching the ceiling, so the last thousand feet cost multiples of the first. The integration (a few hundred ft/min average over a tall climb) is why POH tables exist โ naive division can underestimate time 30%+ on climbs into the teens.
Where does the top-of-climb distance go in flight planning?+
It anchors the navlog's first real leg: from this tool, TOC sits e.g. 13 nm out โ wind-corrected, that's where cruise speed, fuel flow and the first checkpoint timing begin. Skipping it (planning cruise GS from the runway) flatters every downstream ETA on exactly the legs where fuel margins get decided.
Is climb fuel really that different from cruise fuel?+
Per mile, dramatically: full-rich, full-power flow (often 30โ50% above cruise) at two-thirds of cruise speed roughly doubles the gallons per mile. The few gallons this tool reports for the climb buy what they buy โ the planning sin is pretending they were cruise-rate gallons. Tables, and this calculator, price them honestly.
Should I climb high for a short leg?+
Run the trade: the climb costs the minutes and gallons computed here; the cruise repays with TAS and tailwinds for however many miles remain after TOC (and a descent at near-zero cost). The folk threshold โ about 50 nm of leg per 5,000 ft of climb before altitude pays โ falls straight out of running this tool against our cruise planner; your winds move it.
