Aviation tools
Three calculators. They use the numbers you type, and a bundled list of large airports. They are not a flight plan, a performance chart, or a weather briefing.
- Distance and flight time Great-circle distance between two airports, and the time at a ground speed you type. 1174 large airports are in the list.
- Unit converter Knots, km/h, and mph. Feet and metres. Nautical miles and kilometres. inHg and hPa. Celsius and Fahrenheit.
- Crosswind component Headwind and crosswind from a runway heading and a wind you type. The result uses your speed unit. It is not an aircraft limit.
