Define the trip before you draw a line

A cross-country flight starts with the mission, not the chart. Before anything is drawn, write down the purpose, the date, the earliest and latest acceptable arrival time, who is on board, what they are carrying, and whether a return is wanted the same day or later. Put the aircraft’s actual registration and exact model next to it, not “the club 172,” because the registration is what the rest of this course’s worksheets key everything to.

Passenger expectations are a scheduling problem, not a weather problem. A passenger who says “we have to be there by five” is handing you a planning constraint to solve on the ground, days in advance, with a backup plan, not a reason to accept a lower weather margin on the day. Separate the two explicitly: a latest acceptable departure time, an overnight option if the trip slips, a ground-transport fallback, and a number you are willing to spend on a diversion.

Note anything that moves this outside ordinary daytime domestic planning: night flight, unfamiliar or high-density airports, mountainous terrain, overwater legs, or special-use airspace. Each of those needs training and planning beyond what this course covers; flag it rather than plan around it as if it were routine.

Confirm the pilot and the airplane can actually do this

Before researching a single airport, confirm the flight is legal to attempt at all. Check certificate and rating privileges, medical qualification or an applicable alternative, flight review currency, any required endorsements, and passenger-carrying currency — day and night are separate questions under 14 CFR 61.57(a), and an instrument rating does not by itself make a pilot current for anything. Use the actual logbook. Memory is not a records system.

Then the airplane: current documents, operating limitations, a current weight-and-balance, airworthiness directive compliance, and maintenance status, including which inspections actually apply to this operation. An annual inspection and a 100-hour inspection answer different questions — a 100-hour is not automatically due just because the airframe has flown 100 hours, it depends on what kind of operation is being flown (14 CFR 91.409).

If something is inoperative, the question is whether dispatch is permitted: under an approved MEL where one exists, or otherwise directly under 14 CFR 91.213, which asks whether the item is required by the type certificate, by an airworthiness directive, by the kind of operation being flown, or is otherwise required equipment for this specific flight. A placard covering a broken gauge does not by itself satisfy that rule; when in doubt, get a maintenance determination before departure, not after.

An airplane has flown 94 hours since its last 100-hour inspection, and the owner plans to rent it out for flight instruction next week, which would require the inspection. For your personal, non-instructional cross-country this weekend, six hours before that happens, what applies?
AprofundarWhat actually makes an inoperative item acceptable to fly with

Where no MEL applies, 14 CFR 91.213(d) sets out the test directly: the inoperative item is not part of the VFR-day type-certification equipment list or an equipment list specifically required by an airworthiness directive, is not indicated as required on the aircraft’s equipment list for the kind of flight being conducted, is not required by 91.205 or any other applicable rule for the specific operation, and has been either removed or deactivated and placarded “INOPERATIVE,” or repaired, with the determination made and entered in the aircraft records by a person authorized to perform maintenance.

That last clause is the one people skip. A pilot does not get to personally decide an inoperative item is “not needed today” and placard it themselves; the determination that it may be deferred has to come from someone authorized to make it, and it has to be recorded. A sticky placard from a previous owner, with no logbook entry behind it, is not evidence of anything.

Research every airport in three passes

Treat every airport on the route, including fallback airports, the same way: three separate passes, each answering a different question, none of them a substitute for the others.

Pass one is published airport data, from the current Chart Supplement and the current sectional or terminal chart: identifier, coordinates and elevation, public or private status, any PPR condition, runway dimensions, surfaces and slope, pattern altitude and direction, lighting, communications and weather-reporting frequencies, fuel listed, and remarks. Read the remarks. A runway length without its slope, its surface condition, or a remark about a displaced threshold is half the information.

Pass two is current operational notices: NOTAMs for runway and taxiway closures, lighting or navigation-aid outages, temporary flight restrictions, and anything else that would not show up in a saved chart. Record the effective start and end time of each one and whether it overlaps your planned arrival or your return. If the schedule shifts, recheck — a NOTAM that does not apply at your original ETA can apply at your delayed one.

Pass three is a phone call to the airport operator or the FBO that will actually serve you. A fuel icon on a chart or a listing in a commercial directory is a lead, not a confirmation. Call, ask the questions below, and write down who you spoke to and when.

What to confirm with the FBO, by phone, before you file anything

Access
Will the airport and the ramp you need be open at both your arrival and departure times? Local time or UTC? What changes on a holiday?
Combustível
Is your aircraft’s approved grade actually in stock, self-serve or truck service, and available after hours with notice?
Cost
Current fuel price, landing/ramp/handling fees, overnight fees, minimum purchase, and any waiver — confirmed for your category and length of stay.
Parking
Reservations or PPR needed? A public transient ramp, or a separate area for small aircraft? Tie-downs, or hangar/preheat if needed?
Reentry
Gate code or escort needed to reach the aircraft after the office closes? Restroom access for passengers after hours?
Transport
Is a courtesy car actually reservable — and its driver, insurance, range and return rules — or are taxis/rental cars realistically available on arrival?
Contato
A phone number for an after-hours problem, and which services stop before the field itself closes.

An FBO can confirm its own services. It cannot issue an ATC clearance, confirm a charted procedure, or declare an airport officially closed or open — those come from the appropriate operational source, and a conflict between the two is resolved before departure, not explained away.

Choose a route with somewhere to go wrong

Mark the departure, the destination, and at least two sensible fallback airports along the way — airports you could actually land at, with usable runways and, ideally, confirmed fuel, not just the nearest dot on the chart. Evaluate terrain, airspace, weather exposure and communications coverage along the whole route, not only at the two ends.

A route that is a little longer but keeps better airports underneath it, or avoids a complicated airspace transition, is often the better choice. Draw that option and compare its actual time and fuel cost against the direct line rather than assuming direct is automatically best.

Pick recognisable checkpoints before workload rises in flight: a feature near a turn, before an airspace boundary, or where terrain changes, something you could identify without the moving map if it failed. Avoid a small feature that looks like a dozen others nearby, and check whether darkness or season removes the visual cue you are counting on.

For every controlled or special-use area the route touches, write down what compliance actually requires. Flight following is advisory traffic separation, not a blanket clearance into controlled airspace — Class B specifically requires an explicit clearance before entry, and Class C and D each carry their own communication and equipment expectations. Check for TFRs, prohibited and restricted areas, and, if the route goes near Washington, DC, the dedicated SFRA/FRZ procedures and training that subject has its own requirement for and that this course does not provide.

Choose an altitude, and read the chart correctly

Select a cruising altitude by weighing terrain and obstacle clearance, cloud clearance, airspace, climb capability, winds, and, at higher altitudes, oxygen — not by picking a round number that looks safely high on the chart. A sectional’s maximum elevation figure is a conservative obstacle-clearance reference for the quadrant it is printed in; it is not a cleared cruising altitude, and it does not by itself satisfy cloud clearance or airspace requirements. Keep MSL and AGL straight throughout: charted altitudes and most clearances are MSL, cloud clearance and many practical judgments are thought through in AGL above the specific terrain under you.

In level VFR cruising flight more than 3,000 feet above the surface and below 18,000 feet MSL, 14 CFR 91.159 assigns altitude by magnetic course, not heading: 000 through 179 degrees uses odd thousands plus 500 feet, 180 through 359 degrees uses even thousands plus 500 feet, subject to the exceptions stated in the rule itself.

VFR visibility and cloud clearance, by airspace (14 CFR 91.155)

Classe B
3 statute miles, clear of clouds
Class C and D
3 SM; 500 ft below, 1,000 ft above, 2,000 ft horizontal from clouds
Class E, below 10,000 ft MSL
3 SM; 500 ft below, 1,000 ft above, 2,000 ft horizontal
Class E, at or above 10,000 ft MSL
5 SM; 1,000 ft below, 1,000 ft above, 1 SM horizontal
Classe G
Varies with altitude and day/night — consult the full table in 91.155 rather than a single remembered figure

These are legal minimums, not personal targets. “Three miles and clear of clouds” is the Class B figure specifically, not a safe shorthand for every class of airspace, and meeting the legal minimum is not by itself a plan — see Chapter 5 on personal minimums.

14 CFR § 91.155

Verificação rápida

Your planned route has a true course of 310° and 8° east variation. More than 3,000 feet AGL and below 18,000 MSL, which altitudes does 91.159 permit, and why?
AprofundarWhy a single memorized oxygen altitude is not enough

If a planned altitude brings cabin pressure altitude into the range covered by 14 CFR 91.211, check the actual rule rather than one remembered number: it addresses cabin pressure altitude (not simply MSL altitude flown), duration of exposure at each bracket, and who on board needs supplemental oxygen and when. Performance and judgment degrade before a legal threshold is crossed, which is a reason to plan conservatively around this rule, not a reason to treat the rule itself as the safety margin.

Explique

Lido pelo ATLAS

You have planned a direct VFR route between two airports 95 NM apart. A classmate points out there is no usable airport within 20 NM of the route’s midpoint. Explain what you would actually do about that, and why a longer route might be the better plan even though it costs time and fuel.

Cenário de missão

The confirmed stop that turned out not to be

Exercise, fictional airports and aircraft. You are planning a VFR flight landing at Cedar Municipal (invented) at 1930 local. The directory listed Cedar as having “24-hour fuel,” and you called ahead: the FBO confirmed fuel but said their office closes at 1800.

Twenty minutes before your planned departure, you call again to confirm, as you always do. The person who answers tells you the self-service pump has been down for two days and the mechanic will not be out until tomorrow. A passenger has a nonrefundable event booked near Cedar this evening and is already at the airport.

Lake Regional (invented), 18 NM from Cedar, confirms by phone that it has your fuel grade, self-serve, available until 2200, and a public transient ramp with no PPR.

As decisões são definitivas. Você não poderá mudar uma depois de tomada; refaça a missão se quiser tentar outro caminho.

  1. Decisão 01

    You now know Cedar cannot be treated as a confirmed fuel stop tonight. Your original fuel plan assumed topping off there before the return leg tomorrow.

    You have not yet recalculated whether the aircraft can complete tonight’s landing, sit overnight, and depart tomorrow without refuelling at Cedar at all.
