PlaneWX is the Pilot's Decision Support System for general aviation. It combines weather briefing, FRAT, and a mentor network so pilots can see weather and risk, and connect with a mentor before the pressure locks in.

How far in advance can PlaneWX predict flight weather?

PlaneWX provides reliable weather intelligence from 14 days out to departure time. The accuracy improves as your flight approaches, with 76% accuracy at 24 hours, 70% at 48 hours, and 61% at 72 hours.

What is the WX Score?

The WX Score is a personalized 0-100% metric calculated against YOUR personal minimums, not generic VFR/IFR categories. It tells you the probability that weather conditions will meet your specific standards for the flight.

What is Synoptic Intelligence™?

Synoptic Intelligence™ is PlaneWX's proprietary AI technology that synthesizes NWS forecaster narratives, METARs, TAFs, NBM data, and other weather products into regional summaries and actionable insights.

Flight Weather Briefer: Decision Support Before You Fly

A flight weather briefer is the tool or workflow that helps you decide whether a trip still works before pressure locks the plan. For owner-pilots, that call often lands days out, when a solid TAF for your window does not exist yet. Hotels, passengers, and meetings move first. Briefing tools that only light up inside 24 hours arrive late.

A classic briefer got the discipline right. They forced a route-wide view, not one airport icon. They asked about your airplane, your experience, and your outs. They made you say the risks out loud before you launched. The delivery method changed. The job did not.

What a modern flight weather briefer must do

Explain the pattern days out. Area Forecast Discussions and probabilistic blends matter more than a pretty map four days before departure.
Match the mission to the airplane and the pilot. The same ceiling is not the same decision in a FIKI turboprop and a non-FIKI single after a long day.
Stay honest about uncertainty. A percentage or score should show why it moved, not pretend the atmosphere is settled.
Hand off to tactical weather. When TAFs, METARs, radar, and PIREPs take over, the briefer job becomes verification, not a new religion.
Leave the call with the PIC. Decision support is not a dispatch release. Light AI assist can organize products and surface conflicts faster. It does not own go/no-go.

Where PlaneWX sits

PlaneWX is a pilot decision support system built for that earlier window. It structures the weather brief along your route, pairs it with FRAT-style risk framing, and keeps a mentor path available when pressure is high. Forecast-office reasoning and probability data calibrate the trip against your aircraft and personal minimums, then refresh as departure gets closer.

You still need your EFB and official sources on flight day. PlaneWX is for protecting options before pressure locks the plan.

You want to be a safer pilot. You want a high quality weather briefing, scored against your personal mins and aircraft capabilities. You need an honest self assessment. When you are feeling the pressure and the weather is questionable, an objective mentor helps.

How to use a briefer workflow on your next trip

Sketch the route while nothing is locked. Set plain-language limits. Watch the window for several days. Edit early if the pattern moves against you. In the last day, verify with observations. Keep go/no-go yours.

If you have been searching for a flight weather briefer that works before the TAF exists, brief a real trip in PlaneWX. Soft start. You still own the call.

The confidence to go. Or the courage to stay.™
