The Complete VFR Flight Planning Guide

Why Flight Planning Matters

Flight planning is a legal requirement under 14 CFR 91.103, which states that each pilot in command shall, before beginning a flight, become familiar with all available information concerning that flight. For flights not in the vicinity of an airport, this specifically includes weather reports and forecasts, fuel requirements, alternatives available if the planned flight cannot be completed, and any known traffic delays.

Beyond legality, thorough flight planning directly impacts three things:

• Safety. Planning ahead lets you identify hazards on the ground, not in the air at 120 knots. Weather that looks benign on a surface observation can hide icing conditions, wind shear, or convective activity that only becomes apparent when you analyze the full weather picture.
• Efficiency. Proper altitude selection and wind analysis can cut 10-20% off your fuel burn and flight time. Choosing the right altitude to pick up a tailwind or avoid a headwind is the difference between a comfortable flight and a fuel-anxiety flight.
• Situational awareness. A pilot who has studied the route, identified checkpoints, briefed the airspace, and knows the frequencies is a pilot who can manage emergencies, diversions, and unexpected ATC instructions with composure. A pilot who “just goes flying” is reactive instead of proactive.

The NTSB cites inadequate preflight planning as a contributing factor in hundreds of general aviation accidents every year. Most of these accidents were preventable with 30-60 minutes of ground work before engine start.

Pre-Flight Planning Checklist: 12 Items

This is your master checklist. Complete every item before every cross-country flight. Print it out or save it in your EFB. Do not skip items because the flight is short or the weather looks good.

Weather Briefing Deep Dive

Weather is the number one killer in general aviation. More VFR-into-IMC accidents happen because pilots failed to properly brief the weather than for any other reason. A thorough weather briefing is not optional -- it is the foundation of every safe flight.

How to Get a Briefing

You have three main options. First, call 1-800-WX-BRIEF (1-800-992-7433) to speak with a Leidos Flight Service Specialist who will give you a verbal briefing tailored to your route. Second, visit 1800wxbrief.com for a self-briefing where you can pull all the products yourself and generate a briefing record. Third, use an EFB like ForeFlight or Garmin Pilot, which integrate weather briefing into your flight plan automatically. All three methods create a legal record of your briefing.

There are three types of briefings: a standard briefing for flights departing within 6 hours (complete weather picture), an abbreviated briefing to supplement or update a previous briefing, and an outlook briefing for flights more than 6 hours away (general trends, not detailed).

Route Planning

Route planning is where you decide how to get from A to B safely and efficiently. As a VFR pilot, you have several navigation methods at your disposal, and the best pilots use a combination of all of them.

Pilotage

Pilotage means navigating by visual reference to landmarks on the ground. You identify features on your sectional chart -- highways, rivers, lakes, towns, railroads, power lines, airports -- and match them to what you see out the window. This is the most fundamental navigation skill and the one you will use on every VFR flight. Choose checkpoints that are large, unique, and easy to spot from altitude. A major highway interchange is a good checkpoint. A random road intersection is not.

Dead Reckoning

Dead reckoning is navigation by calculation. You measure the true course from your chart, apply magnetic variation to get magnetic course, apply wind correction to get magnetic heading, and apply compass deviation to get compass heading. You calculate groundspeed from TAS and wind, then compute time between checkpoints. Dead reckoning alone will not keep you on course indefinitely (wind estimates are never perfect), but combined with pilotage it is extremely reliable. Use our Wind Correction Calculator to practice these computations.

VOR Navigation

VOR (VHF Omnidirectional Range) stations provide magnetic bearing information. You can navigate along VOR radials or use two VOR stations to fix your position. While GPS has largely replaced VOR for primary navigation, VOR proficiency is still required for your checkride and serves as an essential backup when GPS fails. Victor airways (V-routes) connect VOR stations and provide a structured route system.

GPS Direct

GPS provides the most accurate and convenient navigation available. Most pilots today fly GPS direct between waypoints. However, GPS direct does not relieve you of the responsibility to plan your route for terrain, airspace, and emergency landing options. A straight line between two airports may cross restricted airspace, high terrain, or large bodies of water with no diversion airports. Always evaluate your GPS-direct route on a chart before flying it.

Airspace Considerations

Your route must account for airspace. Class B requires ATC clearance. Class C requires two-way radio communication. Class D requires communication with the tower. Special use airspace (MOAs, restricted areas, prohibited areas) may require avoidance or permission. TFRs can pop up with little notice. Brief the airspace along your entire route, not just at your departure and destination.

Navigation Log

The navigation log (nav log) is your in-flight reference document. It lists every checkpoint along your route with the course, distance, groundspeed, estimated time, and fuel burn for each leg. During the flight, you compare your actual times against your estimates to track progress and detect problems early.

How to Fill Out a Nav Log

Groundspeed and ETE Calculations

To calculate groundspeed, you need true airspeed (TAS) and wind. Start with your indicated airspeed, correct for non-standard pressure and temperature to get TAS, then apply the wind using your E6B flight computer or wind triangle calculation. Once you have groundspeed, ETE in minutes equals distance (NM) divided by groundspeed (knots) times 60. For example: 45 NM at 110 knots groundspeed = 45/110 x 60 = 24.5 minutes.

Space your checkpoints 10-20 NM apart. Closer spacing gives you more frequent position fixes but more entries to manage. Farther spacing is simpler but gives you less situational awareness. For your first cross-countries, err on the side of more checkpoints.

Fuel Planning

Running out of fuel is one of the most preventable -- and most embarrassing -- causes of forced landings. The FAA regulation is clear: under 14 CFR 91.151, no person may begin a VFR flight unless there is enough fuel to fly to the first point of intended landing and, assuming normal cruising speed, to fly after that for at least 30 minutes during the day or 45 minutes at night.

Fuel Burn Rates

Know your aircraft's fuel burn rate at your planned power setting and altitude. A Cessna 172 burns about 8-10 GPH at cruise. A Piper Cherokee burns 8-9 GPH. A Cirrus SR22 burns 13-17 GPH. These are approximate -- always use the POH numbers for your specific aircraft and conditions. Leaning the mixture at cruise altitude can reduce fuel burn by 10-15%.

Use our Fuel Burn Calculator to compute fuel requirements for your specific aircraft and route.

Required Reserves

The legal minimums (30 min day / 45 min night) are exactly that -- minimums. Smart pilots carry more. A common personal minimum is 1 hour of reserve fuel. This gives you margin for unexpected headwinds, holding, diversions, or getting lost. If your fuel calculation shows you will land with less than your personal reserve, either reduce the trip length, plan a fuel stop, or reduce weight to carry more fuel.

Diversion Fuel

Always identify diversion airports along your route and calculate how much fuel you need to reach them from each checkpoint. If weather closes your destination or you encounter an emergency, you need to know immediately where the nearest airport is and whether you have enough fuel to reach it. Mark diversion airports on your chart and note the fuel required in the margin of your nav log.

Weight and Balance

Weight and balance is not just a checkride requirement -- it is a critical safety calculation. An aircraft that is over maximum gross weight will have degraded climb performance, longer takeoff rolls, higher stall speeds, and reduced structural margins. An aircraft with the CG out of limits can become uncontrollable.

How to Calculate

1. List all weights: empty weight (from the aircraft weight and balance sheet), pilot, front passenger, rear passengers, baggage, and fuel (at 6 lbs/gallon for avgas).
2. Multiply each weight by its arm (distance from the datum) to get the moment. Arms come from the POH loading diagram.
3. Sum all weights to get total weight. Verify it is at or below max gross weight.
4. Sum all moments and divide by total weight to get the CG position.
5. Plot the CG on the envelope chart in the POH. Verify it falls within the approved envelope for both takeoff and landing weight.

Use our interactive Weight & Balance tool to practice these calculations with real aircraft presets and CG envelope diagrams.

What Happens When Out of CG

A forward CG makes the aircraft nose-heavy, requiring more back pressure and increasing stall speed. The aircraft is stable but less efficient. An aft CG makes the aircraft tail-heavy, reducing stability. In extreme cases, the elevator authority may be insufficient to prevent a stall or recover from one. Aft CG is the dangerous condition -- the aircraft may become unrecoverable. A lateral CG imbalance (unequal fuel tanks or asymmetric loading) causes a constant wing-heavy tendency that increases pilot workload.

Filing a VFR Flight Plan

A VFR flight plan is not required by regulation, but it is strongly recommended for any cross-country flight. It activates search and rescue (SAR) services -- if you do not arrive and do not close your flight plan, the FAA will come looking for you. This could save your life after an off-airport landing.

How to File

File through 1800wxbrief.com, ForeFlight, Garmin Pilot, or by calling 1-800-WX-BRIEF. You will need: aircraft type and N-number, departure airport and time, route of flight, cruising altitude, destination airport, estimated time en route, fuel on board, number of people, and the color of your aircraft. Filing takes about 5 minutes.

Activating and Closing

Filing a flight plan does not activate it. You must activate it after departure by calling Flight Service on the radio (122.0, 122.2, or a listed RCO frequency) or by phone. ForeFlight can auto-activate based on GPS. When you arrive, you must close your flight plan by calling 1-800-WX-BRIEF or using your EFB. Failure to close triggers the SAR process: Flight Service will start calling your destination airport and phone numbers on file 30 minutes after your ETA.

SAR Timeline

If Flight Service cannot reach you within 30 minutes of your ETA, they begin an information request (INREQ), contacting your destination airport and phone numbers. If they still cannot locate you within 1 hour, they escalate to an alert notice (ALNOT), which triggers the Air Force Rescue Coordination Center. A full-scale search may be launched within hours. This is why closing your flight plan is critical -- false alarms waste expensive search resources.

The Go/No-Go Decision

The go/no-go decision is the final gate before you start the engine. It synthesizes everything you have gathered during planning into a single question: is this flight safe to make today, with this aircraft, in these conditions, with my current state?

Personal Minimums Framework

Personal minimums are limits you set for yourself that are more conservative than the legal VFR minimums. They should be written down before the day of the flight, not made up in the moment when you are feeling pressure to go. Example personal minimums for a newly certificated private pilot:

• Ceiling: at least 3,000 ft AGL
• Visibility: at least 5 statute miles
• Surface winds: 15 knots or less
• Crosswind component: 8 knots or less (use our crosswind calculator)
• No convective activity within 20 NM of route
• No mountain obscuration or IFR conditions forecast
• At least 1 hour fuel reserve beyond destination

As you gain experience, you can gradually raise or lower specific minimums. But always have them, and always honor them.

PAVE Checklist

The PAVE checklist is an FAA-recommended framework for evaluating risk across four categories:

If any single PAVE category raises a red flag, the flight should be postponed or modified. The most dangerous flights are the ones where multiple marginal factors combine -- marginal weather, tired pilot, unfamiliar aircraft, and pressure to arrive. Any one of those factors alone might be manageable. Together, they create an accident chain.

Digital vs. Paper Planning

The debate between digital and paper planning is largely settled: most pilots use digital tools for efficiency and accuracy, but every pilot should know how to plan on paper. Your DPE will likely test paper planning skills on your checkride, and batteries die at the worst possible times.

The best approach is to learn paper planning first (you will need it for your checkride), then transition to digital tools for everyday flying while maintaining paper proficiency. Always carry a backup: if your iPad is your primary EFB, bring a paper chart as backup. If you plan on paper, keep a phone with an aviation app as backup.
