FlightLen Guides
Aviation weather and flight tracking, explained simply
FlightLen is built for pilots, student pilots, aviation students, and curious travelers who want useful context without decoding every abbreviation from scratch. These guides explain the data shown in the live map, METAR checker, TAF forecast, and airport pages.
How To Read METAR and TAF Reports
Learn what wind, visibility, clouds, ceilings, altimeter, and forecast groups mean in everyday language.
How Live Flight Maps Work
Understand callsigns, altitude, speed, heading, aircraft registration, and why some aircraft may not appear.
Runways, Headwind, and Crosswind
A plain-English guide to runway numbers, wind direction, favored runways, and crosswind limits.
VFR, MVFR, IFR, and LIFR
Understand aviation flight categories and why cloud ceilings and visibility matter so much.
Airport Classes for Student Pilots
A practical overview of Class B, C, D, E, and G airports and what learners usually look for.
Student Pilot Weather Checklist
A simple order for checking METARs, TAFs, winds, ceilings, runway choice, and live traffic.
FlightLen Data Sources
Learn where FlightLen gets weather, aircraft, airport, and runway information and what the limits are.
What makes FlightLen different?
Many aviation tools show raw data first. FlightLen keeps the raw reports available, then adds quick summaries so beginners can understand the same conditions pilots are watching: wind, visibility, cloud layers, flight category, traffic density, runway direction, and aircraft movement.
