Aviation Calculators
Free aviation calculators for airspeed conversion, density altitude, crosswind component, fuel planning, descent rate, and flight nav.
Pressure Altitude Calculator
Calculate pressure altitude from altimeter setting and field elevation. Essential for performance charts, density altitude, and aviation flight planning.
Top of Climb Calculator
Calculate time, distance, and fuel burn from takeoff to top of climb (TOC). Plan reaching cruise altitude using climb rate, ground speed, and fuel flow.
Aviation Wind Correction Angle Calculator
Calculate the wind correction angle and ground speed for any flight. Enter true airspeed, course, and wind to get heading, ground speed, and crab angle.
Glide Ratio and Range Calculator
Calculate glide ratio, maximum glide range from altitude, minimum descent rate, and best glide speed for any aircraft. Essential for engine failure planning.
Mach Number Calculator
Calculate Mach number from airspeed and altitude. Convert between TAS, EAS, CAS, and Mach number. Find the speed of sound at any altitude and temperature.
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, 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.
