VFR flight plan guide
A good VFR flight plan is more than a filed form. It is a route, weather picture, fuel plan, alternate plan, and communication plan that still makes sense when the first assumption changes.

Quick answer: build a VFR flight plan by checking the required preflight information, choosing a route and altitude that fit the weather and aircraft, calculating fuel with reserves, selecting real alternates, filing or briefing through an official source, and remembering to open and close the plan.
The legal floor is preflight action. 14 CFR § 91.103 requires each pilot in command to become familiar with all available information concerning the flight. For a flight away from the vicinity of an airport, that includes weather reports and forecasts, fuel requirements, alternatives if the planned flight cannot be completed, and known traffic delays.
Start with the mission, not the magenta line
Before choosing checkpoints, write the flight in plain English: departure, destination, passengers, baggage, daylight window, weather tolerance, fuel stops, and why the trip needs to happen today. That framing keeps the plan from becoming a route you defend instead of a decision you evaluate.
Build the route
- Airspace: identify controlled airspace, special-use airspace, restricted areas, TFRs, and practical radio expectations.
- Terrain and obstacles: pick altitudes that leave margin, especially at night or in reduced visibility.
- Glide options: compare route segments against reachable airports and suitable off-airport areas. The glide-aware VFR flight planner is built for this step.
- Runway wind: check departure, destination, fuel stop, and alternate crosswind components with the runway crosswind calculator.
- Checkpoints: use checkpoints that are visible and useful, not just evenly spaced.
Weather and timing
Read METARs, TAFs, winds aloft, AIRMETs, SIGMETs, convective outlooks, NOTAMs, and the broader weather picture. Aviation Weather Center publishes METAR and TAF data at aviationweather.gov, but a full preflight briefing remains the better source for a complete operational picture.
Put all timing on a Zulu clock before comparing products. A TAF valid window, NOTAM window, fuel stop ETA, sunset, and destination arrival should be compared on the same basis. If you need a refresher, use the Zulu time calculation guide or the pilot UTC / Zulu time converter.
Fuel plan
Calculate fuel from the POH/AFM and actual expected conditions, then add reserves that fit the flight. The regulatory minimum is not always the practical minimum. Wind, taxi time, climb fuel, routing changes, missed approach to landing, and a diversion leg can all matter on a VFR cross-country.
| Fuel item | What to include |
|---|---|
| Taxi and runup | Expected ground time, delays, and training-area departures. |
| Climb | POH/AFM climb fuel and time adjusted for density altitude. |
| Cruise | True airspeed, winds aloft, and planned power setting. |
| Descent and arrival | Arrival routing, pattern work, and possible delay. |
| Reserve and diversion | Legal reserve plus personal buffer and a real alternate leg. |
File, activate, and close
Filing a VFR flight plan helps search and rescue know where to look if you do not arrive, but it is only useful when it is activated and closed. The FAA Aeronautical Information Manual discusses flight plan procedures, including pilot responsibility for activating VFR flight plans with Flight Service, in AIM Chapter 5, Section 1.
A practical go/no-go pass
Before engine start, ask four questions: does the aircraft fit the mission, does the weather fit the pilot, does the route leave outs, and does the plan still work if one major assumption changes? If one answer is weak, change the plan while you are still on the ground.
