Free Aviation Tools & Calculators

Aviation calculators for pilots and dispatchers

The weight and balance calculator computes CG position from fuel, passengers, and baggage against aircraft envelope limits. The density altitude calculator gives pressure altitude corrected for temperature - the number that actually determines aircraft performance.

Our crosswind component calculator gives headwind and crosswind components from wind direction, speed, and runway heading. For aerospace engineering tools, see our Aerospace tools. For travel planning tools, see our Tourism tools.

Always verify calculations against your aircraft's approved flight manual and current NOTAMs. These tools are for reference and training use only.
