The Five P Check, Plan, Plane, Pilot, Passengers, Programming, and the Five Decision Points Where You Actually Run It

The Five P check is an in-flight risk management tool that has you review five factors - Plan, Plane, Pilot, Passengers, and Programming - at five set decision points during every flight. It exists to catch the slow “drift” of small changes that individually seem harmless but collectively add up to a flight you never would have agreed to on the ground. You can run the entire check in your head in about fifteen seconds, and it costs you nothing.

Why Knowing About Risk Isn’t Enough

For decades, flight training taught risk like a textbook: here are the hazards, here is the definition of a hazard, here is aeronautical decision making. Students could recite all of it, pass the knowledge test, and then go make the exact same fatal choices pilots have made since the Wright brothers.

The reason is simple. Knowing the definition of risk and recognizing risk while strapped into a moving airplane at 3,000 feet with your family behind you are two completely different skills. One is a vocabulary quiz. The other is a fight.

This is why the FAA shifted toward scenario-based training. Instead of “define a crosswind,” the prompt became “you’re on final, the windsock just swung - what are you going to do about it?” Real situations, real decisions. To help single pilots manage this without a copilot to catch them, the FAA built several memory tools, including the DECIDE model and the PAVE checklist you run before you leave the ground. The Five P check is the one you run in the air.

What Are the Five Ps?

Most accidents that kill capable, current, legal pilots aren’t caused by one giant, obvious mistake. They’re caused by a slow drift - a series of small changes that each seemed fine. The Five Ps force you to look at each one.

1. Plan. The mission itself: your route, weather, fuel, terrain, airspace, and alternates. The key question isn’t “what was the plan” - it’s “what has it become.” The weather you briefed at six in the morning is not the weather you’re flying at two in the afternoon. Compare the flight you’re actually on to the flight you planned, and be honest about the gap.

2. Plane. The airframe and systems. Fuel state, engine instruments, electrical, and everything behind the panel. Any airplane can develop a problem in flight - a rough magneto, an alternator that quietly stopped charging, a leaking door seal. Ask: is this still the machine I departed in?

3. Pilot. This is you, and it’s the P everyone wants to skip because it’s uncomfortable. Are you fatigued, hungry, or dehydrated (which sneaks up faster at altitude)? Are you stressed about getting home or the meeting tomorrow? The airplane doesn’t care how you feel - but how you feel will write every decision you make for the rest of the flight.

4. Passengers. A sneaky risk factor most new pilots never consider. A nervous passenger changes your decisions. A passenger who really needs to get to a wedding creates pressure you’ll feel even if nobody says a word. And a pilot-passenger in the right seat can lull you into relaxing when you shouldn’t. Ask: who is in this airplane, and how are they bending my judgment right now?

5. Programming. Your avionics - GPS, autopilot, EFIS, and the tablet running your moving map. In a modern cockpit, the number one way to lose situational awareness is to put your head down in a menu, fingering a knob to make the magenta line behave, while the airplane keeps flying toward terrain that doesn’t care about your data entry. Ask: is the automation set up correctly, do I understand what it’s doing, and am I flying the airplane - or is it flying me?

When Do You Actually Run the Five P Check?

A checklist is worthless if you never pull it out. So the FAA doesn’t just say “use the Five Ps” - it tells you when. There are five natural decision points in almost every flight:

1. Preflight - before you go.
2. Pretakeoff - at the hold-short line, right before you commit.
3. Top of climb - the moment you level off in cruise and finally get a second to breathe.
4. Midpoint - halfway to your destination. This is the one everybody forgets, and it’s the most important.
5. Predescent - before you dive into the busy, task-saturated part of the flight where pattern, traffic, and radio all pile up at once.

Preflight, Pretakeoff, Top of climb, Midpoint, Predescent. Five points, five Ps. It’s built to be remembered.

How the Drift Actually Happens: A Real Scenario

Picture a Saturday. You’re a fresh private pilot with about 80 hours total, flying a rented Cessna 172 on a 200-mile cross-country to see a friend. You did your PAVE and your preflight Five Ps - ceilings high, winds light, you’re rested and fed. At top of climb you run the Five Ps again: Plan good, Plane good, Pilot feels great, no passengers, Programming tracking. A beautiful flight.

Then lunch with your friend runs long. It’s now 3:00 in the afternoon instead of noon. Your friend says he’s never been up in a small plane and asks to ride back partway. Sure. Why not?

That’s the exact moment the drift begins - so gently that nobody notices it in real time without a tool forcing them to look. Watch what happens to your Five Ps if you don’t run the check:

• Plan changed completely. You’re flying a new leg to an unfamiliar airport you never briefed, and the afternoon buildups are starting to pop on the horizon.
• Plane is heavier now, and your fuel planning was for a different trip.
• Pilot isn’t the same person who launched. You’ve been up since five in the morning, flew 200 miles, ate a big lunch, and it’s the sleepy part of the afternoon.
• Passengers now includes a first-time flyer who trusts you completely and has no idea what a bad decision even looks like.
• Programming is about to demand a new destination loaded while you hand-fly into an unfamiliar field.

Every single P changed - and not one of them changed enough to scare you. That’s the whole point. That’s how it kills people.

How Running the Check Changes the Outcome

Now run the Five Ps at the midpoint of that return leg. You’re level, halfway home, and you say the five words to yourself:

• Plan: My plan changed completely and I never re-briefed it.
• Plane: I’m heavier than planned - let me recheck fuel.
• Pilot: I am genuinely tired, and I need to admit it.
• Passengers: My friend is depending on me and doesn’t know the risks, so I have to be the adult here.
• Programming: Let me load this new airport now, while it’s calm - not on a two-mile final.

The check doesn’t necessarily tell you to turn around. What it does is drag the drift up out of the background and put it where your decision-making brain can see it. It converts a vague, uneasy feeling into five specific facts you can act on. That is scenario-based decision making: not memorizing definitions, but building the habit of stopping at set points to honestly compare the flight you’re on to the flight you meant to be on.

How Does the Five P Check Show Up on the Checkride?

If you’re training now, this isn’t just wisdom - it’s on the test. The Airman Certification Standards (ACS) dedicate an area of operation to risk management, and the examiner is looking for something specific. They don’t want you to recite what the letters stand for; any parrot can do that. They want you to demonstrate that you can identify risk in a real situation and manage it before it becomes an emergency.

So when your examiner leans over during the cross-country and says, “it’s getting a little hazy and we’re running later than planned - what are you thinking?”, that’s an engraved invitation to run the Five Ps out loud. Talk through it: “Plan has changed because we’re behind schedule and visibility is dropping. Pilot - I notice I’m rushed and want to slow down. Here’s my plan B, here’s my out.” That’s a pass. The examiner wants a pilot who sees the picture changing and does something about it - not one who reacts only after the airplane is already in trouble.

Build the Habit Before It Matters

The acronym is not the point. The acronym is just the handle. The point is the habit of stopping and asking, at a few fixed moments in every flight, “is this still the flight I signed up for?” The pilots who get hurt are almost never the ones who lacked knowledge - they’re the ones who had a slow-moving situation change around them and never built in a moment to look up and notice.

You don’t need a glass cockpit, an app, or another rating. You need five words and the discipline to say them to yourself five times a flight. On your very next flight - even if it’s just a few laps in the pattern - pick your decision points and run the Five Ps out loud. Make it boring. Make it automatic. Because when it actually matters, you won’t rise to the occasion; you’ll sink to the level of your habits. Build the habit now, while the stakes are low.

This breakdown draws on the FAA’s own risk management guidance in the Pilot’s Handbook of Aeronautical Knowledge and the risk management area of the Airman Certification Standards - both free to anyone with an internet connection.

Key Takeaways

• The Five Ps are Plan, Plane, Pilot, Passengers, and Programming - a 15-second in-flight review that catches the slow “drift” of small, individually harmless changes.
• Run the check at five decision points: preflight, pretakeoff, top of climb, midpoint, and predescent. The midpoint check is the one most pilots skip and the one that matters most.
• The most dangerous risk is cumulative, not a single obvious mistake - each small change feels acceptable until they add up to a flight you never would have accepted on the ground.
• The check’s real value is converting a vague unease into five specific, actionable facts you can do something about.
• On the checkride, the ACS wants demonstrated risk management, not recitation - running the Five Ps out loud is exactly what the examiner is listening for.
