Definition
A single-pilot risk management tool that organizes in-flight decision-making around five categories: the Plan (route, weather, fuel, timing), the Plane (aircraft mechanical condition and equipment), the Pilot (fitness, currency, fatigue, stress), the Passengers (their experience, comfort, and influence on decisions), and the Programming (the avionics, autopilot, and GPS the pilot is managing). The pilot deliberately reviews all five at key checkpoints during a flight to identify changes that may require a new decision.
Plain English
A short mental checklist a pilot runs at set points during a flight to make sure nothing important has changed about the trip, the aircraft, themselves, the people on board, or the equipment they are operating.
Context Anchor
Used in single-pilot resource management, especially during preflight planning, before takeoff, during cruise, before descent, and whenever conditions change.
Derivation
Each P stands for one category the pilot must check: Plan, Plane, Pilot, Passengers, Programming. The five-word grouping makes the check easy to recall in the cockpit without referring to a written list.
Why Pilots Care
It gives a pilot a repeatable way to spot problems early and make safer go/no-go or continue/divert decisions.
Intuition Check
The Five Ps are not five fixed actions to perform in order. They are five areas to review so the pilot can make a better decision as the flight changes.
Example Sentence 1
Before beginning the descent, the pilot ran the Five Ps and realized the forecast crosswind at the destination had increased beyond their personal limits.
Example Sentence 2
Halfway through the flight the pilot paused to recheck the Five Ps after a change in weather altered the original plan.
