Aviation Tools& Calculators

Paste a raw METAR to decode wind, visibility, clouds, temperature, altimeter, and flight category (VFR/MVFR/IFR/LIFR) at a glance.

Decode terminal aerodrome forecasts into readable time-grouped weather periods with wind, visibility, and cloud conditions.

Calculate density altitude and pressure altitude from elevation, QNH, and temperature to understand true aircraft performance.

Estimate ground roll and takeoff distance over a 50 ft obstacle based on weight, density altitude, and wind.

Calculate required landing distance and stopping distance based on approach speed, weight, and runway conditions.

Enter station weights to compute total weight and center of gravity, and verify you are within CG limits.

Top of descent via the 3:1 rule, top of climb, and the descent rate required to make a crossing restriction.

Resolve wind into headwind and crosswind components from wind direction, speed, and runway heading.

Calculate the wind correction angle and true groundspeed required to maintain your desired track.

Convert indicated altitude to true altitude using temperature deviation from ISA standard.

Calculate holding pattern entry type, timing, and leg lengths based on speed and wind.

Find the equal time point and point of no return between two airports for diversion planning.

Plan routes and discover where to fly on an interactive globe. Range rings for your aircraft, fuel and payload effects, flight-time filters, and curated scenic destinations across 4,500+ airports.

Plot a multi-leg journey across 4,500+ airports, pick the aircraft for each leg, and total your distance and flight time. Your trip is saved in your browser.

Import your SimBrief flight plan and view a formatted brief with route, weather, alternates, fuel data, and a terrain elevation profile along your planned route.

Plan trip fuel with taxi, contingency, alternate, and final reserve fuel blocks.

Solve any leg of the E6B flight computer triangle - enter two values to calculate the third.

Calculate true airspeed from IAS at any altitude and temperature, plus Mach number and speed of sound.

Convert fuel quantities between kilograms, pounds, US gallons, and litres for any fuel type.

E6B-style aviation unit conversions: distance, speed, pressure, temperature, weight, and more.
