The Five P check and the four decision points where you actually run it on a cross-country

The Five P check is an FAA aeronautical decision-making tool that prompts you to evaluate five risk areas - Plan, Plane, Pilot, Passengers, and Programming - at key moments during a flight, not just before it. The power of the tool is that it’s tied to specific in-flight decision points, the moments where most dangerous “press-on” choices actually get made. Run it at four points on a cross-country: preflight, hold-short, top of descent (or any change in conditions), and before the approach.

What Problem Does the Five P Check Solve?

Most aeronautical decision-making (ADM) tools are front-loaded. You run your risk checklists in the flight planning room with coffee in hand - no engine running, no clock pressure, no passengers asking how much longer.

But the accident record is clear: deadly decisions usually aren’t made in the planning room. They’re made in the airplane, in motion, after something has changed and you’re already emotionally and financially committed to the flight. The airplane is rented, people are on board, and you told everyone you’d be there by dinner.

The Five P check exists to interrupt that. It forces a structured look at your situation at specific moments during the flight. It comes straight out of the FAA’s work on single-pilot resource management and appears in the FAA Risk Management Handbook.

What Are the Five Ps?

1. Plan. This is the basic mission - weather, route, fuel, terrain, airspace, and NOTAMs. The key idea is that the Plan is a living thing, not a document you printed and stopped reading. The Plan you made at 6 a.m. is not the same Plan at 2 p.m. when the forecast has already started to be wrong. The question isn’t “what was my plan?” It’s “is my plan still true right now?”

2. Plane. The mechanical airframe and, increasingly, the avionics. Is the airplane up to this? How is the fuel actually burning compared to plan? Be honest about the rough mag you talked yourself out of during runup, the door seal that whistles, the alternator light that flickered. The Plane asks you to assess the machine you’re actually in - not the one you wish you had.

3. Pilot. That’s you. Run something like IMSAFE on yourself, but in flight rather than just before it. Fatigue is sneaky. You felt great at takeoff, but three hours later - after bumpy legs, a tricky frequency change, dehydration, and hunger - you’re not the same pilot. Are you still sharp enough for the hardest part, the approach and landing at the end?

4. Passengers. An underrated risk source. Passengers create pressure: the boss who needs to make the meeting, the airsick spouse who wants this over, the friend you’re trying to impress. That pressure usually pushes you toward “press on.” But passengers are also a resource - a non-pilot can hold a chart, spot traffic, read you the next frequency, or simply be told, “I need quiet for the next ten minutes.”

5. Programming. The avionics, autopilot, GPS navigator, moving map, and tablet. Is the box set up for what’s about to happen? Have you loaded the approach? Does the autopilot know what you want - and do you know what it’s actually doing? Head-down time spent fighting a magenta line is some of the most dangerous time in aviation, because while you’re reprogramming, nobody is flying the airplane and nobody is looking outside.

When Do You Actually Run the Five P Check?

A checklist you don’t use isn’t a tool - it’s a poster. The genius of the Five P is that the FAA tied it to four specific decision points where you’re already shifting gears, so adding thirty seconds of structured thought costs almost nothing.

Decision Point 1: Preflight, on the Ground

This is the obvious one, and you’re already doing most of it. The difference is to run the five by name, even on a clear day. Plan - still good? Plane - ready? Pilot - am I ready? Passengers - who’s coming and what do they need? Programming - is the box loaded for departure? You don’t want the first time you run the Five P under pressure to be the first time you’ve ever run it.

Decision Point 2: Before Takeoff, at the Hold-Short Line

This is a moment we waste. We finish the runup, make the radio call, and just go. But the hold-short line is the last completely free decision you’ll make on that flight. After the throttle goes up, every option gets more expensive and more committed. Sit for one extra breath: Am I comfortable with this departure and weather? Am I ready, or rushing because there’s a Cessna behind me? Is the first fix loaded and the autopilot armed the way I want? Examiners look for exactly this - proof that the hold-short line is a thinking moment, not just a place you idle.

Decision Point 3: En Route, at Top of Descent or Any Change

This is the one that saves lives, because this is where get-there-itis lives. Somewhere over the middle of your cross-country, the picture changes. Ceilings ahead are lower than the TAF promised, the headwind is eating fuel, you’re behind schedule. Deliberately stop and run all five - out loud if you’re alone - because the whole point is to break the momentum.

A real scenario: You’re flying a Cessna 172 about a three-hour leg to see family, with marginal VFR forecast to improve by afternoon. Two hours in, it hasn’t. You’re down to 1,500 feet, scud running, telling yourself it’s fine because the destination is only 30 minutes out. Your kid is in the back. You promised grandma dinner.

Run the five:

• Plan: My plan assumed improving weather. That assumption is now false. The plan is broken.
• Plane: The airplane’s fine, but I’m burning more fuel down low, and I haven’t done the math in an hour.
• Pilot: I’ve been hand-flying in bumps and haze for two hours. I’m tense, and an approach into an unfamiliar field in bad weather is still ahead. I am not the pilot I was at takeoff.
• Passengers: My kid in the back is the entire reason my gut wants to press on - and the entire reason I shouldn’t.
• Programming: Am I even set up for an instrument approach if this falls apart, and am I current and legal to fly one? If not, that’s a screaming signal.

Run honestly, and the decision makes itself: divert to the field 40 miles back that was still VFR, buy fuel and a vending-machine sandwich, call grandma, dinner’s late, everybody lives. The tool didn’t make the choice for you - it made you actually look at the choice instead of sliding past it.

Decision Point 4: Before the Approach (or in the Pattern at an Untowered Field)

This is your last gate. Before you start down the glideslope or turn base, run a quick five. Plane - is fuel state and configuration where it should be? Pilot - am I ahead of the airplane or behind it? Programming - is the approach loaded, the missed approach in there, do I know my numbers? Passengers - have I told them I need quiet? Plan - what’s my out? A go-around should never be a surprise; it should already be loaded in your head before you ever need it.

Why Willpower Alone Doesn’t Beat Get-There-Itis

Flying is hard and expensive, and there’s real pressure baked into every cross-country, because you spent money to get somewhere and your brain hates wasting it. Nobody is immune.

The Five P check doesn’t make the pressure disappear. What it does is give you four moments to step outside the pressure and look at it from the outside. You can’t fight get-there-itis with willpower in the moment, because in the moment your judgment is the thing that’s compromised. You fight it with a habit you built when you weren’t under pressure.

Your Practical Takeaway

Pick the four decision points - preflight, hold short, top of descent (or any change), and before the approach. Tape a card to your kneeboard if you have to. At each one, run the five words: Plan. Plane. Pilot. Passengers. Programming. Out loud if you’re solo. It takes about twenty seconds, and most of the time everything checks green and you fly on. The point isn’t to find a problem every time - it’s that on the one day there is a problem, you have a structure that catches it instead of a gut that talks you past it.

If you’re a student, bring this to your instructor. Ask them to fly a scenario where the weather goes bad en route, and practice running the Five P at top of descent and making the diversion call. Under the Airman Certification Standards (ACS), examiners put you in exactly these scenarios and watch how you think. They aren’t looking for a perfect flight - they’re looking for a pilot who notices when the plan breaks and does something about it.

Key Takeaways

• The Five Ps are Plan, Plane, Pilot, Passengers, and Programming - a structured in-flight risk review from the FAA Risk Management Handbook.
• The tool’s real value is running it at four decision points: preflight, hold-short, top of descent or any change in conditions, and before the approach.
• Most dangerous decisions are made in motion after conditions change - not in the planning room - which is exactly when the Five P interrupts your momentum.
• The core question for the Plan is always “is my plan still true right now?” - and a broken assumption is a flag to stop and reassess.
• You beat get-there-itis with a pre-built habit, not in-the-moment willpower, because under pressure your judgment is already compromised.
