Flyable

Flyable gives general aviation pilots a clear, personalized Go, Marginal, or No-Go recommendation for every flight — based on live weather, your aircraft, and your personal minimums.

Select your aircraft. Enter your departure, destination, waypoints, and alternate. Tap Evaluate. Flyable pulls real-time data from official FAA sources and checks every factor against the limits you’ve set: ceiling, visibility, crosswind, gusts, turbulence, icing, thunderstorms, density altitude, runway length, and more.

No subscription. No account. No ads.

Just a straightforward weather briefing tool built by a pilot (Kyle), for pilots (you).

For iPhone & iPad.

WEATHER DATA

  • Live METARs with flight category (VFR/MVFR/IFR/LIFR)

  • Terminal Aerodrome Forecasts (TAFs) with thunderstorm and ceiling alerts

  • Pilot Reports (PIREPs) within 200 nm — turbulence, icing, and weather

  • AIRMETs and SIGMETs filtered to your route corridor with content-aware severity

  • Active NOTAMs for every airport on your route

  • Density altitude with performance impact estimates

  • Clear-sky confirmation — positive green indicators when no ceiling exists

PERSONAL MINIMUMS

Set separate VFR and IFR minimums for ceiling, visibility, crosswind, max surface wind, gust spread, temp/dewpoint spread, turbulence tolerance, and more. Flyable evaluates every factor and tells you exactly which ones are within limits and which ones aren’t.

AIRCRAFT LIBRARY

Preloaded with 55 GA aircraft including Cessna 172, Cessna 182, Piper Archer, Cirrus SR22, SR22T, Bonanza A36, Diamond DA40, DA42, Piper Seminole, Baron 58, Pilatus PC-12, TBM 960, King Air 250, Citation CJ3+, Vision Jet, and many more. Each includes full POH performance data for takeoff roll, landing distance, climb rate, crosswind limits, service ceiling, and gross weight. Adding a new aircraft? Search our built-in database by make and model to auto-fill all performance data instantly.

SMART FEATURES

  • Best runway recommendation based on current winds — falls back to longest runway when winds are calm or variable

  • Headwind and crosswind component calculations

  • Dynamic route corridor advisory filtering — SIGMETs and AIRMETs filtered by geographic proximity to your route, not just a fixed radius

  • Night flight detection with sunrise/sunset awareness

  • Runway length vs. aircraft performance checks at actual density altitude

  • IFR alternate requirement checks

  • Shareable weather briefing text for your records

  • Flight history log — tap any past flight to rerun the weather evaluation

  • Smart airport code entry — type CHD and it auto-resolves to KCHD

  • 20,000+ US airports with runway data from OurAirports

  • Automatic network retry with exponential backoff for reliable data fetching

SAFETY

  • First-launch safety disclaimer — must acknowledge before using the app

  • Density altitude is advisory-only — never produces a false No-Go; runway and performance factors handle hard limits

  • Route hazards auto-expand when a No-Go is present so nothing is hidden

  • Content-aware SIGMET evaluation — convective SIGMETs are No-Go; turbulence and icing SIGMETs are checked against your personal minimums

  • 76 automated unit tests covering decision engine, corridor filtering, aircraft performance, and weather parsing

DATA SOURCES

All weather data comes directly from the FAA’s Aviation Weather Center — the same source used by major EFBs. Runway data is sourced from OurAirports, covering 37,000+ airports worldwide. No third-party APIs, no middlemen.

Flyable is a decision aid only.
Always obtain a standard weather briefing from official
sources and exercise your own judgment as pilot in command.
