Definition
A single-pilot risk management checklist that organizes flight risk into five review areas: the Plan (route, weather, fuel, NOTAMs, publications, timing), the Plane (mechanical condition, fuel state, equipment, databases), the Pilot (fitness to fly, often assessed using IMSAFE), the Passengers (their experience, comfort, expectations, and any pressure they create), and the Programming (avionics, autopilot, GPS, and other automation the pilot must manage in flight). The pilot reviews all five at key decision points -- preflight, pretakeoff, hourly cruise check, predescent, and before approach and landing -- to catch changes before they compound into a hazardous situation.
Plain English
A five-part check a pilot runs through at set points during a flight to make sure nothing has changed in a way that adds risk. The five parts are the trip plan, the aircraft, the pilot, anyone on board, and the cockpit equipment that needs to be set up and managed.
Context Anchor
Used in single-pilot risk management, especially during preflight planning and at key points in flight when the pilot needs to reassess risk.
Why Pilots Care
Ensures no critical factor is overlooked, reducing the risk of accidents caused by poor decision-making or resource mismanagement.
Grounding Statement
The 5P check is a quick way to ask, “Has anything important changed that should change my decision?”
Intuition Check
Do not read these as just five ordinary nouns. In this context, each word names a specific area of flight risk that the pilot must actively review.
Example Sentence 1
Before starting the descent, she ran the 5Ps and realized the Programming needed updating because ATC had assigned a different approach than the one already loaded.
Example Sentence 2
Mid-flight, unexpected weather prompted another 5P review to adjust the Plan and check the Pilot's fatigue.
