Definition
A single-pilot risk management tool that prompts the pilot to review five categories of risk — the Plan, the Plane, the Pilot, the Passengers, and the Programming (avionics and automation) — at key decision points during a flight, such as preflight, pretakeoff, cruise, predescent, and before approach and landing.
Plain English
A quick mental checklist a pilot runs at set points in a flight to check five things that commonly cause problems: the trip itself, the aircraft, themselves, the people on board, and the cockpit equipment they're using.
Context Anchor
Used during preflight planning and again at key points in flight, especially when conditions change or a decision needs to be made.
Derivation
Each 'P' stands for one of the five risk categories — Plan, Plane, Pilot, Passengers, and Programming. The label is a memory aid, not a word with deeper origins.
Why Pilots Care
Provides a repeatable way to spot hazards early, reducing the chance of an accident caused by overlooked factors in single-pilot flights.
Intuition Check
Do not think of the 5P Check as only a box to mark before takeoff. It is a repeatable pause for making safer decisions before and during the flight.
Example Sentence 1
Before starting the descent, she ran the 5P Check and realized the weather at the destination had dropped below her personal minimums.
Example Sentence 2
When the destination weather deteriorated, the pilot performed another 5P Check and decided to divert.
