Takeoff & Landing Distance
Estimate runway ground-roll requirements with transparent constant-acceleration models. Use measured POH data for real operations; this tool is for concept checks and classroom sensitivity studies.

Speed errors square into distance errors
Ground roll follows \(s = V^2 / 2a\), so a small increase in liftoff or touchdown speed produces a larger increase in distance.
Open Source and Easy to Use Elsewhere
