Free Aviation Tools — Built for Pilots

Calculate crosswind and headwind components for any runway and wind condition. Visualize wind vectors, compare multiple runways at once, and check against your personal minimums.

Whether you're planning a flight or studying for your PPL, understanding crosswind components is essential. This calculator gives you instant answers with a clear visual breakdown — and it's useful long after you pass your exam.

Paste any raw METAR or TAF report and get a complete plain-language translation. See flight categories, weather alerts, and timeline analysis at a glance.

Reading raw METARs and TAFs is a skill every pilot needs — and one that's tested on the written exam. Use this decoder to practice reading weather reports and to quickly check conditions at any airport.

Convert between all the units pilots encounter daily — distance, speed, pressure, temperature, altitude, volume, weight, and time. Built specifically for aviation with the conversions you actually need.

Nautical miles to statute miles. Millibars to inches of mercury. Celsius to Fahrenheit. If you've ever fumbled a conversion during flight planning or on a practice exam, this tool solves that instantly.

Calculate aircraft weight and balance with CG envelope visualization. Add stations, adjust fuel loads, and verify your center of gravity is within limits — all with a clear visual display.

Weight and balance is tested on every FAA written exam and is critical for safe flight operations. This tool lets you practice CG calculations and verify your work with an interactive envelope chart.

Calculate pressure and density altitude with the full scientific method. Understand how temperature and humidity affect aircraft performance with detailed impact analysis.

Density altitude is critical for safe flight operations, especially at high elevations on hot days. This calculator helps you understand the real impact on takeoff performance and climb capability.

Solve the wind triangle from your true course, true airspeed, and the winds aloft. Get true heading, ground speed, and the wind-correction angle for every leg of your cross-country.

The wind triangle is core to navigation on the written exam and in the cockpit. Practice solving for heading and ground speed here instead of spinning an E6B — then check your manual work against it.

Plan the fuel for a leg from distance, ground speed, and burn rate. See fuel required, endurance, and whether you meet your reserve — before you ever start the engine.

Running the numbers on fuel required vs. fuel aboard is a go/no-go decision on every flight and a favorite of written-exam questions. Use this to build the habit and to sanity-check your flight-log math.

Enter the holding course and your inbound heading and get the recommended entry — direct, teardrop, or parallel — with the sector geometry that drives it.

Picking the right holding entry under pressure trips up instrument students constantly. Drill the direct/teardrop/parallel decision here until the sectors are second nature for the IFR written and your checkride.

Convert between local time and Zulu (UTC) and compute an ETA from a departure time and en-route duration. Built for the way pilots actually track time.

Aviation runs on Zulu time, and mixing up the offset is an easy way to blow an ETA or a clearance. Practice the conversions and ETA math here so the mental model sticks.

Look up the key V-speeds — Vs, Va, Vx, Vy, and more — for common training aircraft, with weight-adjusted stall and maneuvering speeds where the physics allow.

V-speeds are memory items for your checkride and safety-critical in the cockpit. Use this reference to study the numbers for your trainer and to understand which speeds change with weight and why.

Estimate takeoff and landing distances for common trainers from field elevation, temperature, wind, and weight — with a runway-margin check against the length you have.

Takeoff and landing performance is a go/no-go decision and a heavily tested topic. Use this to build intuition for how density altitude, wind, and weight stretch your distances — then always confirm with the POH chart.
