For travellers
The flight time calculator gives the great-circle distance between two airports, an estimated flight time, the time difference and your local arrival time on a route map. The airport code lookup turns the three-letter IATA code on your ticket or bag tag into the airport name, city and country, along with its ICAO code and local time. The jet lag calculator builds a sleep and light plan for the days before and after your flight; adapting after eastward flights is usually harder.
For pilots and enthusiasts
The METAR decoder fetches the latest METAR and TAF for any airport, or decodes a pasted report, and translates every group into plain English: wind, visibility, cloud base, temperature and pressure. The pilot calculator works out crosswind and headwind components for a runway, plus density altitude, true airspeed, flight time and fuel in E6B style. These tools are meant for training and pre-flight planning; for real flights always use official briefing sources and your aircraft’s flight manual.
Your flight’s carbon footprint
The flight carbon calculator estimates CO₂e per passenger and in total from the distance, cabin class and number of travellers, using official conversion factors. Business and first class seats take up more space in the cabin, so their share of the emissions per passenger is higher than economy. On short routes, take-off and climb make up a larger part of the trip, so emissions per kilometre are usually higher than on long-haul flights.
