Takeoff & Landing Performance
Enter field elevation, altimeter, temperature, and weight to get takeoff and landing ground roll and over-50-ft distances, then add a headwind and a safety margin and check whether it all fits on your runway. The method is the useful part: pressure and density altitude → chart interpolation → wind and safety-margin adjustment → runway-fit check.
Takeoff and landing numbers are inherently aircraft-specific, so the chart grid here is a clearly-labeled PA-28-140 worked exampledigitized from the 1964 Owner's Handbook (paved, level, dry, no wind). Every input is editable so the method is visible for any light single — but the numbers you fly must come from your own POH.
Short by 954 ft — the over-50-ft distance overruns 2,600 ft of runway. Add runway, reduce weight, or wait for cooler air.
| POH | Wind-adj | + margin | |
|---|---|---|---|
| Ground roll | 1,501 | 1,006 | 1,509 |
| Over 50 ft | 3,166 | 2,369 | 3,554 |
Use YOUR POH. The chart grid here is a worked PA-28-140 example(1964 Owner's Handbook — paved, level, dry, no wind), illustrative for training only. The wind and safety-margin steps are estimates beyondthe POH chart. Read your own aircraft's charts for the numbers you fly.
