Landing Distance
About Land Dist
What this tool does
Aviation tools convert airspeeds (IAS, TAS, CAS), calculate density altitude, determine crosswind and headwind components, estimate fuel endurance, compute weight and balance, and plan takeoff distances.
Why use this tool
Pilots must perform these calculations before every flight. Density altitude affects engine performance and runway requirements. Crosswind determines whether a landing is within aircraft limits. Getting these numbers right is a safety essential.
How it works
Density altitude corrects pressure altitude for non-standard temperature using the ISA model. Crosswind splits the wind vector into headwind and crosswind using sine and cosine of the angle difference. Weight and balance sums moments and checks against the CG envelope.
Pro tip
On hot, high-altitude days, density altitude can exceed field elevation by thousands of feet. Always recalculate takeoff distance with the actual density altitude, not the field elevation.
