Cross-Country Flight Planning: A Student Pilot's Complete Guide

What is a cross-country flight?

The FAA defines a cross-country flight in two ways depending on the context. For logging purposes, a cross-country is any flight with a landing at a point other than the departure airport that involves use of dead reckoning, pilotage, electronic navigation, or radio aids — and is more than 50 nautical miles straight-line from the departure airport. For the PPL solo cross-country requirement, at least one leg must be 50+ nm from the departure point.

The solo cross-country requirements for a Private Pilot License are:

• 5 hours of solo cross-country time
• One cross-country of at least 150 nm total with full-stop landings at a minimum of 3 points, one leg at least 50 nm straight-line from departure

Step 1 — Route selection

Start by picking your destination and drawing the most direct route on a sectional chart. Then evaluate that route for the following before committing:

• Terrain — are there mountains, ridges, or terrain that require minimum crossing altitudes? VFR pilots must maintain 500 ft above the highest obstacle within 4 nm of the route in non-mountainous areas, and 2,000 ft above the highest obstacle within 4 nm in mountainous areas.
• Airspace — does the route pass through or under any Class B, C, or D airspace? Military operating areas? Restricted or prohibited areas? Mark them on your sectional.
• Landmarks — identify prominent visual checkpoints every 10–15 nm: towns, rivers, lakes, highways, airports. These are your dead reckoning confirmation points.
• Fuel stops — can you complete the route with required reserves, or do you need to stop? Never depart without completing the fuel calculation.
• Alternate airports — identify airports along the route where you could divert if weather deteriorates or you have an emergency.

Choosing cruise altitude

VFR altitude rules (FAR 91.159) require: when flying on a magnetic course of 0°–179°, fly at odd thousands + 500 ft (3,500, 5,500, 7,500). When flying on a magnetic course of 180°–359°, fly at even thousands + 500 ft (4,500, 6,500, 8,500). Below 3,000 ft AGL, the hemispheric rule doesn't apply.

Choose altitude based on terrain clearance, wind (winds aloft forecast), airspace, and aircraft performance. Higher altitudes typically provide better glide distance in an emergency and more favorable winds for long flights.

Step 2 — Weather briefing

You must obtain a preflight weather briefing before any cross-country flight. The standard source is 1800wxbrief.com (Leidos Flight Service). A standard briefing covers:

• Adverse conditions — PIREPs, SIGMETs, AIRMETs along the route
• VFR flight not recommended (VNR) advisory if applicable
• Synopsis — overall weather pattern
• Current conditions — METARs for departure, en-route, and destination airports
• Forecast — TAFs, area forecasts, prog charts
• Winds and temperatures aloft forecast (FD winds)
• NOTAMs — for all airports you'll use
• ATC delays, if applicable

Reading winds aloft (FD/FB winds)

Winds aloft forecasts are issued four times daily for altitudes from 3,000 to 53,000 feet. Format: DDSSHH — two-digit direction (in tens of degrees), two-digit speed (knots), two-digit temperature (°C). Example: 2715-04 = wind from 270° at 15 knots, temperature -4°C.

Use the winds aloft forecast to compute your true heading and groundspeed for each leg. The classic method uses the E6B flight computer (or our digital fuel planner) to resolve the wind triangle.

Step 3 — Navigation log

The navigation log (nav log) is the core planning document for a VFR cross-country. It organizes all your calculations into a flight-by-flight-segment format. For each leg, compute:

True course

Measure the true course from your sectional using a plotter. This is the direction of your planned flight path relative to true north.

Wind correction angle (WCA) and true heading

Using winds aloft data and your true airspeed, compute the wind correction angle using the E6B. True heading = True course ± WCA. This is the direction you must point the nose to track the desired course over the ground.

Magnetic heading

True heading ± magnetic variation = magnetic heading. Magnetic variation is shown on sectional charts as isogonic lines. East variation subtracts, west variation adds (TVMDC — True Variation Magnetic Deviation Compass).

Compass heading

Magnetic heading ± compass deviation = compass heading. Deviation is found on your aircraft's compass correction card.

Groundspeed and leg time

Use the E6B to compute groundspeed for each leg given true airspeed and wind. Leg time = distance ÷ groundspeed.

Fuel burn

Fuel per leg = leg time × fuel burn rate. Sum all legs plus taxi/runup, reserve, and alternate fuel. Compare to fuel on board — this is your go/no-go fuel check.

Step 4 — FAA fuel requirements (FAR 91.151)

For VFR day flight, you must have enough fuel to fly to the first point of intended landing and then fly for at least 30 minutes at normal cruise speed. For VFR night flight, the reserve is 45 minutes. These are legal minimums — most experienced pilots plan for significantly more.

The reserve fuel is calculated at cruise fuel burn, not best economy — don't shortchange it. If in doubt, add a fuel stop. Running low on fuel is one of the most preventable causes of GA accidents.

Step 5 — NOTAMs

Check NOTAMs for every airport you plan to use, plus any major airports near your route. Critical things to look for:

• Runway closures at your departure or destination airport
• Temporary flight restrictions (TFRs) — VIP movement, wildfires, stadiums
• NAVAID outages (VOR, ILS, ATIS)
• Unlit towers or obstructions along your route
• Changes to airspace structure or frequencies

NOTAMs are available through 1800wxbrief.com, ForeFlight, or the FAA's NOTAM search at notams.aim.faa.gov.

Step 6 — Weight & balance

Complete a weight and balance calculation for your specific loading. Do not skip this step — CG outside limits is a real safety issue, not a paperwork formality. See our W&B Calculator for C172 and PA-28.

Remember: the calculation you do before departure assumes the fuel load at departure. Your CG will shift as you burn fuel. For most training aircraft with passengers in front seats only, this shift is small and predictable — but always verify.

Step 7 — Departure and en-route procedures

Filing a flight plan

VFR flight plans are not legally required for domestic US flights, but they are highly recommended for cross-country flights over remote or unfamiliar terrain. A VFR flight plan filed with Leidos (via 1800wxbrief.com, ForeFlight, or phone) means search and rescue will be notified if you don't close it within 30 minutes of your destination ETA. Always close your flight plan on arrival.

En-route navigation

As you fly, update your nav log at each checkpoint. Record the actual time over each checkpoint and compare to your planned time. If you're off by more than a few minutes, recalculate your groundspeed and ETA to identify the cause — you may have stronger or weaker winds than forecast.

If you can't identify a checkpoint when you expect it: don't panic. Maintain your heading and continue flying — the next checkpoint may appear before your expected one does. If you remain unsure of your position, use the "5 C's": Climb, Communicate (with ATC or CTAF), Confess (to ATC that you're uncertain), Comply (with ATC instructions), and Circle (maintain position while you assess).

Common student pilot cross-country mistakes

• Skipping the weather briefing — especially tempting on "obviously nice" days. Get the briefing anyway; you'll find NOTAMs and PIREPs you didn't expect.
• Underestimating fuel — always add margin. Legal minimums are bare minimums, not comfortable ones.
• Not filing a flight plan — if you get lost or have an emergency over remote terrain, you want SAR looking for you.
• Wrong magnetic variation — double-check the isogonic line on the sectional for your route. East is least, west is best (add west variation to true course).
• Forgetting to check TFRs — TFRs can appear with little notice. Penetrating a presidential TFR is a major violation with serious consequences.
• Not closing the flight plan — leaving an open VFR flight plan triggers a search. Always close it on arrival, even if you're tired.
