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 from pressure altitude 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.

Find your top of descent point using the 3:1 rule - 3 nautical miles per 1,000 ft of altitude to lose.

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.

Visualise how far your aircraft can fly from any airport on an interactive globe. Search 4,500+ airports, set fuel load and payload, and see your reachable range in real time.

Pick a departure airport and discover where you can fly in MSFS 2024. Filter by distance, add your aircraft for estimated flight times across 4,500+ airports.

Import your SimBrief flight plan and view a formatted brief with route, weather, alternates, and fuel data.

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.

Convert between indicated airspeed (IAS), true airspeed (TAS), and Mach number at any altitude and temperature.

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

General aviation unit conversions: distance, speed, pressure, temperature, and more.
