How do I plan a VFR cross-country flight?

Plan a VFR cross-country flight by checking aircraft and aerodrome suitability, current weather, NOTAMs, charts, airspace and terrain; then choose the route, altitude and checkpoints. Calculate wind-corrected headings, groundspeed, times, fuel and performance, and set firm limits for departure, continuation, diversion, turn-back and landing.

This answer sits within our Aviation & Real-World Flying section. We treat VFR planning as a real-world operational task first and a simulator exercise second. For an actual flight, use current official aeronautical information, approved aircraft data and the rules applicable to that aircraft, flight and jurisdiction.

VFR cross-country planning: the route-to-fuel sequence

Complete the plan in this order so that an unsuitable aircraft, aerodrome, route or forecast is found before time is spent calculating every leg.

1. Define the flight. Record the aircraft, departure, destination, expected departure time, occupants, baggage, daylight limit and purpose of the flight.
2. Check aircraft and aerodrome suitability. Confirm runway dimensions and surfaces, operating restrictions, fuel availability, local procedures and whether the aircraft can meet take-off, climb and landing requirements.
3. Set limits before reading the forecast. Write down minimum visibility and cloud base, maximum surface wind and crosswind, fuel margins, daylight margin and any turbulence or precipitation limits. Personal limits may be stricter than legal VFR minima.
4. Collect current information. Review charts and publications, NOTAMs, temporary airspace information, weather observations, forecasts and winds for the planned time and altitude.
5. Select the route. Compare the direct track with safer alternatives around terrain, controlled or restricted airspace, water, congested areas and regions with poor forced-landing options.
6. Select an altitude. Account for terrain, obstacles, airspace, cloud, cruising-level rules, winds, visibility, glide options and aircraft performance throughout climb, cruise and descent.
7. Divide the route into legs. Measure true track and distance, select recognisable checkpoints and mark catching features beyond important turns.
8. Calculate each leg. Use forecast wind and aircraft performance data to obtain heading, groundspeed, elapsed time and fuel.
9. Build the complete fuel plan. Add start and taxi, take-off and climb, cruise, descent, contingency, diversion, final reserve and any additional fuel required by the circumstances or applicable rules.
10. Set decision points. State where and when you will continue, turn back, divert, delay or cancel. Recheck weather, NOTAMs, aircraft status and assumptions shortly before departure.

A mistake we see constantly is drawing the desired straight line first and then trying to make weather, airspace and fuel fit around it. If the direct route leaves no workable altitude or diversion, change the route before completing the navigation log.

Route-to-fuel planning checklist

What do VFR XC and VFRXC mean?

VFR XC and VFRXC are informal shorthand for a VFR cross-country flight. They do not determine whether the flight qualifies as cross-country time for a licence, rating, logbook or training requirement; that definition depends on the applicable regulations and purpose of the flight.

How should I assess VFR cross-country weather?

Assess VFR cross-country weather across the whole route and flight period, not from one favourable observation at each end.

• Present conditions: establish the actual visibility, cloud, wind, pressure, precipitation and significant weather. An observation does not promise that those conditions will persist.
• Forecast timing: compare forecast changes with departure, checkpoint, destination and diversion times. Treat uncertain timing and temporary deterioration conservatively.
• Winds aloft: use the forecast for the planned altitude and time. Headwinds affect endurance, crosswinds change heading, and strong winds around terrain can create turbulence and downdraughts.
• Cloud and terrain: confirm that a legal and safe altitude remains available without becoming trapped between rising ground, cloud and controlled airspace.
• Convection and icing: legal visibility does not make thunderstorms, airframe icing or severe turbulence acceptable. Change the route, time or go/no-go decision rather than planning close avoidance.
• Surface wind: compare the forecast runway wind with aircraft data and personal limits at the departure, destination and diversions. Consider gusts, runway orientation and wet, contaminated or soft surfaces.
• Escape weather: check conditions behind and beside the route. A turn-back or diversion is of little use if the same weather blocks every alternative.

Legal VFR minima are a floor, not a target. A pilot with limited recency, an unfamiliar route or high terrain needs more margin than a simple local flight. Set numerical triggers before departure, such as a minimum cloud base, maximum crosswind, latest departure time and minimum fuel at a named checkpoint.

Do not use surface wind for cruise calculations or assume every source expresses wind direction in the same true or magnetic reference. Check the convention used by the weather product, chart and cockpit instruments before applying the wind.

How do I choose a VFR route, checkpoints and altitude?

Choose the direct route only when it provides acceptable terrain clearance, airspace access, weather margins, landmarks and landing options; otherwise use a safer dogleg.

Read every route in three dimensions. Check airspace bases, tops, vertical references and lateral boundaries during climb and descent as well as cruise. Pilots using US charts can review our explanation of airspace, terrain, obstacle and aerodrome symbols on a VFR sectional.

Measure each leg with the correct chart scale and direction. Our manual plotter and chart-ruler procedure shows how to obtain true track and distance without confusing a reciprocal course or the wrong scale.

• Prefer line features: coastlines, major roads, railways, rivers and ridges are usually easier to identify than a small village or isolated mast.
• Space checkpoints usefully: they should reveal drift or timing error before it becomes large. Ten to fifteen minutes may suit a slow training aircraft in good visibility, but speed, terrain and landmark density change the interval.
• Add catching features: mark an obvious feature beyond a turn or destination so that an overrun is detected.
• Record expected times: a checkpoint without an ETE does little for dead reckoning or fuel monitoring.
• Mark frequencies and clearance points: prepare for frequency changes and permission-required airspace before reaching the boundary.

Our guide to choosing and using visual checkpoints covers pilotage, catch lines and what to do when a landmark does not appear on time.

How do I choose a VFR cruising altitude?

Select an altitude that simultaneously satisfies terrain and obstacle clearance, applicable VFR cruising-level rules, cloud clearance, airspace constraints and aircraft performance.

Do not apply a remembered odd-or-even altitude rule universally. The applicable rule can depend on jurisdiction, track, altitude and airspace. Winds, turbulence, density altitude, visibility and glide range also affect the choice. If no satisfactory altitude exists, change the route or timing rather than forcing the flight through a narrow vertical gap.

How do I calculate VFR heading, time and leg fuel?

For each leg, convert the charted true track into a wind-corrected heading and groundspeed, then use groundspeed for time and the applicable aircraft fuel flow for leg fuel.

1. Measure true track and distance. Label the result in degrees true and nautical miles, or state clearly if another consistent unit is being used.
2. Find planned true airspeed. Use approved aircraft performance data for the expected mass, power, altitude and temperature.
3. Apply the forecast wind. A flight computer, wind triangle or suitable planning tool gives wind-correction angle and groundspeed. Aviation wind direction describes where the wind comes from.
4. Find true heading. Use true heading = true track + signed wind-correction angle. A correction into wind keeps the desired track over the ground.
5. Convert the heading. Apply local magnetic variation to obtain magnetic heading, then the aircraft compass-deviation correction when a compass heading is needed. Keep true, magnetic and compass values in separate columns.
6. Calculate ETE. Use ETE in hours = distance in NM ÷ groundspeed in kt, or ETE in minutes = distance in NM ÷ groundspeed in kt × 60.
7. Calculate leg fuel. Use leg fuel = ETE in hours × planned fuel flow per hour.

Worked VFR cross-country navigation-log example

This example is deliberately generic and is not performance data for a real aircraft. It assumes 95 kt true airspeed, wind from 320° true at 15 kt, variation 4° west and cruise fuel flow of 10 US gallons per hour. Compass deviation is not shown; a real log must apply the correction for the specific aircraft and heading.

For the second leg, 36 NM ÷ 108 kt × 60 = 20 minutes. Its fuel is 20 ÷ 60 × 10 US gal/h = 3.33 US gal, entered as 3.3 US gallons. Keep unrounded figures through the calculation and round the final requirement conservatively.

How do I calculate total block fuel?

Total block fuel covers the complete planned operation, not merely the cruise legs. Category names and required amounts differ between jurisdictions and operations, so use the applicable rules and approved aircraft method.

Using the illustrative cruise result above, suppose the planning figures are:

• Start and taxi: 1.0 US gal
• Take-off and climb: 1.5 US gal
• Cruise legs: 7.0 US gal
• Descent and approach: 0.7 US gal
• Contingency: 1.0 US gal
• Diversion: 3.3 US gal
• Final reserve: 5.0 US gal
• Additional delay allowance: 1.0 US gal

First calculate trip fuel: 1.5 + 7.0 + 0.7 = 9.2 US gal.

Then calculate block fuel: 1.0 taxi + 9.2 trip + 1.0 contingency + 3.3 diversion + 5.0 final reserve + 1.0 additional = 20.5 US gal.

Take-off fuel would be 20.5 − 1.0 = 19.5 US gal. Planned fuel remaining after the destination trip segment would be 20.5 − 1.0 − 9.2 = 10.3 US gal, assuming none of the contingency, diversion or additional fuel was used.

Final reserve is protected landing fuel, not extra range for finishing the intended route. The example uses 30 minutes at 10 US gal/h, giving 5.0 US gallons, only to demonstrate the arithmetic. The required duration, fuel-flow basis and reserve treatment must come from the rules governing the actual flight. Avoid adding a category twice when an approved planning method already includes it.

Which unit checks prevent bad fuel calculations?

• Time: divide minutes by 60 before multiplying by an hourly fuel flow.
• Distance and speed: nautical miles divided by knots gives hours. Do not combine nautical miles with miles per hour.
• Fuel volume: litres per hour produces litres; US gallons per hour produces US gallons. US and Imperial gallons are not interchangeable.
• Fuel mass: kilograms per hour produces kilograms and pounds per hour produces pounds. Use an approved conversion when loading data and fuel-flow data use different units.
• Usable fuel: compare block fuel with usable fuel, not total tank capacity. Respect tank-selection, feed, imbalance and unusable-fuel limitations.
• Climb and descent: do not treat every phase as cruise. Short flights can use a substantial proportion of their fuel in climb.

Other frequent errors are using true airspeed as groundspeed, reading the wind backwards, applying magnetic variation twice and rounding every leg down. Label each column and write the units beside every fuel figure.

How do I check aircraft performance and loading?

Use the approved POH or AFM and the aircraft’s current loading records to verify mass and balance, take-off distance, climb capability and landing distance.

Apply only the corrections permitted by the aircraft data for mass, pressure altitude, temperature, wind, runway slope and surface condition. Published figures may assume a particular technique and aircraft condition; any regulatory or operator safety factor is separate unless the source explicitly includes it.

Check more than whether the centre of gravity lies inside the envelope at take-off. Fuel burn can move the centre of gravity, and a diversion landing may occur at a different mass from the intended destination. High density altitude can reduce acceleration and climb performance even when the runway length appears comfortable.

Cessna 182 cross-country planning

A Cessna 182 plan must use the approved POH or AFM, supplements and current mass-and-balance data for that specific aircraft. Do not substitute generic C182 cruise fuel flow, usable fuel, loading limits, take-off and landing performance, climb figures or crosswind data.

Model, serial range, engine, propeller, tank installation and modifications can change the figures. A demonstrated crosswind component is not automatically a limitation unless the approved document identifies it as one; the pilot’s personal crosswind limit may still need to be lower. In a simulator, use documentation for the modelled variant, but never carry simulated data into a real flight plan.

Limits and decision points

A saved cross-country flight planning PDF is a dated working record, not a replacement for current charts, weather, NOTAMs or approved aircraft information. Record when the briefing was obtained so stale information is obvious.

How should I plan a diversion?

A useful diversion plan identifies reachable aerodromes, the event that triggers the change and the fuel needed to arrive with the required reserve intact.

Record likely tracks, distances, terrain, airspace, runway suitability, weather and frequencies. A nearby aerodrome is not a genuine option if cloud, terrain, runway conditions or permission-required airspace makes it inaccessible.

Choose decision points early. If weather is deteriorating ahead, turning back while there is ample fuel and daylight is routine; waiting until the destination is unreachable can make every remaining choice worse. Our practical method for planning and flying a diversion explains how to establish a safe heading and altitude before refining the calculations.

Recalculate expected landing fuel after a delayed departure, stronger headwind, route deviation or missed checkpoint. If the forecast reserve will no longer be preserved, divert or land before the reserve becomes the only fuel left.

What is the difference between a VFR navigation log and an ATS flight plan?

A VFR navigation log is the pilot’s route, heading, time and fuel worksheet; an ATS flight plan is information submitted to an air traffic services unit for handling, coordination and, where applicable, alerting or search-and-rescue purposes.

For readers searching for a vlucht plan, the same distinction applies: a personal navigation worksheet, an electronic route loaded into an aircraft and a filed ATS flight plan are not interchangeable.

When must a VFR flight plan be filed, opened, amended or closed?

The answer depends on the jurisdiction, route, airspace and type of operation. International flights, specified routes, remote areas or particular airspace may carry filing requirements even when a simple domestic VFR flight does not.

• File: submit the plan within the applicable timing and format rules. Acceptance of the data does not mean that every route segment has been cleared.
• Open or activate: some systems require a separate departure or activation action. Do not assume filing, receiving a reference or departing from a staffed aerodrome automatically opened it.
• Amend: report material changes using the locally prescribed procedure, particularly when route, timing, endurance or destination information changes.
• Close: make the required arrival report after landing unless the applicable service has confirmed automatic closure. Failure to close a plan can trigger overdue action.

A flight plan, traffic service or flight following does not replace a clearance required for controlled, restricted or otherwise permission-dependent airspace. Nor does it remove the pilot’s responsibility for VFR weather, terrain clearance, navigation and fuel.

How do I practise VFR cross-country planning in a flight simulator?

Use the same route, payload, fuel assumptions, wind calculations and navigation log, but do not let an automatic route generator make the planning decisions.

• Begin with fixed weather. A known wind makes heading, groundspeed and ETE errors easier to diagnose. Use variable or live weather later for replanning practice.
• Limit moving-map use. Fly headings and checkpoint times, then review the map after the flight to identify drift or a poor landmark choice.
• Update the log. Record actual checkpoint times and revise ETA and landing fuel after delays or unexpected winds.
• Practise an early diversion. Change destination while several safe options still exist rather than waiting until fuel or weather becomes critical.
• Expect data differences. Simulator scenery, weather, navigation data and airspace may not match real-world publications.

A route loaded into a simulator’s world map, GPS or flight-management system is not a filed or activated real VFR flight plan. Simulated ATC may simplify clearances and services, and simulator information must never be used as the operational source for a real flight.

When is a VFR cross-country plan ready?

The plan is ready when every leg is flyable and you can state exactly what will make you depart, continue, turn back, divert, land or cancel.

• Each leg has a route, checkpoint, distance, heading, altitude, groundspeed, ETE and fuel figure.
• The route remains legal and safe through climb, cruise and descent.
• Weather meets both regulatory minima and written personal limits throughout the relevant period.
• Take-off, climb and landing performance work at realistic mass, temperature, wind and runway conditions.
• Total block fuel is within usable-fuel and loading limits, with final reserve protected.
• Diversions are reachable before weather, fuel or daylight removes them.
• Charts, weather, NOTAMs and aircraft information are current for the flight.
• Clearance points, frequencies and flight-plan actions are understood before departure.
