Practical preflight decision-making, from the framework down to the forecast — written for US Part 91 GA pilots.
Home › Pilot Guides
Free, practical guides on preflight decision-making from the FlightDecide team — no sign-up, no paywall. Each guide takes one piece of the go/no-go picture — the decision framework, your personal numbers, the forecast, the NOTAMs — and turns it into something you can actually use before the next flight.
A repeatable structure for the decision: PAVE worked through concretely, binary calls made early, and what a marginal "caution" flight requires.
Your own hard numbers for ceiling, visibility, wind, runway, and fuel — how to set them, slide them with conditions, and keep them honest.
Decode every group in a terminal forecast so you can see whether your departure window improves or decays.
The NOTAMs that actually change a go/no-go — closed runways, unlit obstacles, TFRs — and how to find them in the noise.
Headwind and crosswind components at steady and gust speeds, instantly.
What today's heat and elevation do to the runway your airplane thinks it's on.
Printable write-in worksheet for setting your ceiling, visibility, wind, runway, and fuel numbers.
FlightDecide pulls weather, winds, NOTAMs, fuel, performance, and W&B for your aircraft and departure window, compares them against your personal minimums, and gives you a GO / CAUTION / NO GO advisory you can verify against the raw data.
