What it does
Before the flight, during it, and after.
Three jobs, and most pilots come for one of them. Take whichever brought you here — nothing assumes you want the other two.
Brief the flight
Route weather, approach capability, fuel and alternates, and a plain-language risk summary — checked against the minimums you set.
Keep people informed
Your family hears when you depart and when you land. SMS or email, double opt-in, and nothing for you to remember on the ramp.
Study and stay sharp
Concepts that go as deep as you want to take them, every rung naming its source, and a tutor that tells you when it doesn't know.
And the rest of it
Personal minimums
Zero-tolerance hazards, departure ceilings, crosswind limits. Every brief is judged against yours.
Weather explorer
G-AIRMETs, SIGMETs, icing, turbulence and en-route METARs, filtered to your route corridor.
Logbook & currency
Import from any EFB. Currency, recency and hours-in-type stay current on their own.
Debrief & replay
The GPS track on a map, the approaches flown, and a record that fills itself in.
Your aircraft
Avionics and performance for each aeroplane you fly. The brief adapts to the one you're in.
Free tools
Pivotal altitude, the flight envelope, XC requirements. No account, no limit, no email.
How it works
Three steps to a smarter preflight.
Enter your route
Type your departure, destination, and cruise altitude. Add waypoints and alternates if you have them.
Get your brief
91 Dispatcher pulls live weather, NOTAMs, and approach data — then evaluates it against your personal minimums and aircraft.
Fly informed
Review a plain-language risk assessment with go/no-go recommendations. See exactly what to watch for en route.
Why 91 Dispatcher
Your flight apps show you data. We tell you what it means.
ForeFlight, Garmin Pilot, and 1800wxbrief are excellent tools — we use them too. But they hand you raw METARs, TAFs, and NOTAMs and leave you to interpret them. 91 Dispatcher reads all of that through the lens of your aircraft, your experience, and your personal minimums — then gives you a risk-calibrated recommendation specific to this flight, today.
