Aviation Calculators
Free online aviation calculators for airspeed, density altitude, crosswind, fuel planning, and flight navigation.
Aircraft Weight and Balance Calculator
Calculate aircraft center of gravity (CG) from weights and arms. Verify CG is within limits before flight. Essential pre-flight check.
Aviation Fuel Burn Calculator
Plan your flight fuel requirements from distance, TAS, fuel burn rate, and alternate fuel reserves. Covers trip fuel, reserve, and alternate requirements.
Climb Gradient Calculator
Calculate aircraft climb gradient (feet per nautical mile) from rate of climb and groundspeed. Check obstacle clearance requirements.
Crosswind Component Calculator
Calculate the headwind and crosswind components for any runway from wind direction and speed. Check against your aircraft's maximum demonstrated crosswind.
Density Altitude Calculator
Calculate density altitude from field elevation, altimeter setting, and outside air temperature. Critical for takeoff and climb performance planning.
Flight Dead Reckoning Calculator
Calculate flight time, ground speed, and fuel required from distance, true airspeed, wind component, and fuel burn rate. Essential for VFR and IFR flight planning.
Runway Length Required Calculator
Estimate runway length required for takeoff based on aircraft weight, density altitude, wind, and slope. For planning — always use POH performance charts.
Top of Descent Calculator
Calculate when and where to start your descent for a smooth 3-degree arrival. Find the Top of Descent (TOD) point in nautical miles from your destination.
True Airspeed Calculator (TAS)
Convert Calibrated Airspeed (CAS) to True Airspeed (TAS) using altitude and outside air temperature. Essential for accurate flight planning and navigation.
