SimpleAvWx — Simple Aviation Weather for iPhone

What it does

Your airports

Each saved airport is a square showing its flight rule category (VFR, MVFR, IFR, LIFR), with wind and temperature from the latest METAR.

METAR & TAF, decoded

Raw METAR and TAF reports with a plain-language decode, including density altitude, plus 24-hour and 10-day outlooks.

Visualize winds

Headwind, tailwind and crosswind components for every runway, with a crosswind calculator one tap away.

D-ATIS & RVR

Digital ATIS text and runway visual range (touchdown, midpoint, rollout) at airports that publish them.

Radar overlay

Radar with lightning, cell tops, and a 2-hour look-back animation.

Import your trip

Import your trip sequence, share it with others, and get ATC traffic delay updates.

Flight tracking

Track and save flights from your schedule. Find your inbound flight, or search other flights by flight number or N-number.

Not for navigation. SimpleAvWx is a convenience tool. It is not an FAA-approved source of weather, airport, or flight planning information. Data can be late, missing, or wrong. Before every flight, get an official briefing, for example from 1800wxbrief.com or aviationweather.gov. The pilot in command is responsible for the safety of the flight. See the Terms of Use.

Where the data comes from

METAR, TAF, and flight category: NOAA / National Weather Service Aviation Weather Center (aviationweather.gov), delivered through the SimpleAvWx server.
D-ATIS and RVR: FAA feeds, delivered through the SimpleAvWx server. Available at airports that publish them.
Hourly and 10-day outlook: Apple Weather (WeatherKit). Data sources.
Radar, lightning, and cell tops: NOAA / NWS radar services, the Iowa Environmental Mesonet (Iowa State University), and NOAA GOES satellite lightning data.
Airport and runway information: OurAirports and aviationweather.gov station data. Magnetic variation is calculated from NOAA's World Magnetic Model.
Flight positions, filed routes, ground stops, ground delay programs, and EDCTs: FAA System Wide Information Management (SWIM) feeds, processed by SimpleAvWx. It is not official FAA information and may be delayed, incomplete or unavailable during outages. Route fix locations come from aviationweather.gov.
