Aviation Calculators
Planning aids for hobby and student pilots: airspeed, crosswind, fuel, descent, weight and balance and cost. Not for flight operations: use your aircraft's approved flight manual and current weather.
Pressure Altitude Calculator
Pressure altitude from field elevation or indicated altitude and the altimeter setting
True Airspeed Calculator
True airspeed and Mach number from calibrated airspeed, pressure altitude and temperature
Crosswind Component Calculator
Crosswind and headwind or tailwind components from wind direction, speed, gusts and runway number
Wind Correction Angle and Ground Speed Calculator
Wind correction angle, true heading and ground speed from course, true airspeed and wind
Fuel Endurance and Range Calculator
Endurance, range and trip fuel from fuel on board, burn rate and ground speed, with a 30 or 45 minute reserve
Top of Descent Calculator
Distance to start descending and descent rate for a 3 degree path, with the divide-by-300 rule of thumb
Flight Time Calculator
Flight time, distance or ground speed from the other two, in nautical miles, miles or km and knots, mph or km/h
Weight and Balance Calculator
Total weight, moment and center of gravity from the weight and arm of each item, checked against your limits
Flight Cost Per Hour Calculator
Owning cost per flight hour from fixed yearly costs, fuel and hourly costs, and the break-even against renting
