## Description

Aviation Tool is a comprehensive Chrome extension designed for aviation enthusiasts and professionals alike. It offers a suite of small but essential tools tailored to assist you during flights. Key features include unit conversion, extra fuel calculation, crosswind calculation, and meteorological calculators providing minimum usable flight levels, ISA deviations, density altitude, and humidity levels.

The extension also provides navigation calculators to determine wind direction, speed, heading, groundspeed, and wind correction angles. Additional utilities include airport information integrated with weather and Google Maps, NOTAMs (Notice to Airmen), direct NOAA weather queries, Snowtam decoding, aviation abbreviations, and Volmet frequencies for Europe and North Africa. This tool consolidates vital flight data into one convenient app, enhancing pre-flight planning and in-flight decision-making.

## Review summary

Review consensus is mixed: the app is praised for being simple, lightweight, and useful for pilots with an easy interface, yet it suffers frequent reliability issues such as NOTAMS and weather data outages, missing ICAO data, and dependence on external apps. Some updates temporarily fixed TAF/METAR, and a few users remain long‑time fans, but many request broad fixes, improved self‑contained functionality, and better device compatibility, especially for Android One. Widget instability is another recurring complaint.

### Pros

- Simple and easy to use, great app, thank you!
- Light software and very useful.
- I like the app. Nice and easy to use.
- Good for pilots.
- Super app. I have used it for years.

### Cons

- NOTAMS and weather data (TAF/METAR) not working or unreliable.
- ICAO dictionary/database missing or needs fixing.
- App requires installation of many other apps / external dependencies.
- Weather/widget keeps crashing and loses settings; 'problem loading widget' issues.
- Incompatibility with some devices and overall functionality degraded over time.
