Definition
A practical single-pilot risk management check used in general aviation, in which the pilot pauses at key points in a flight to evaluate five categories of risk: the Plan (route, weather, fuel, regulations), the Plane (mechanical condition, equipment, fuel state), the Pilot (fitness, currency, experience), the Passengers (their needs, experience, and possible influence on decisions), and the Programming (avionics, autopilot, GPS, and other automation). The check is performed at predefined decision points such as preflight, pretakeoff, cruise, predescent, and before approach, allowing the pilot to update their assessment as conditions change.
Plain English
A simple checklist a pilot runs through at set points in the flight to ask, 'Is anything about my plan, my aircraft, me, my passengers, or my equipment changing in a way I need to deal with?'
Context Anchor
Used in single-pilot resource management training, preflight planning, and in-flight decision-making, especially when conditions change.
Derivation
The phrase originates from the five aviation elements that each begin with the letter P, creating a simple mnemonic for resource management in the cockpit.
Why Pilots Care
It helps a lone pilot catch overlooked factors that could lead to poor decisions or loss of situational awareness.
Grounding Statement
If weather worsens, fuel runs lower than expected, a passenger feels sick, or avionics become distracting, the Five Ps give the pilot a quick way to organize the decision.
Intuition Check
Do not treat the Five Ps as five emergency steps to complete once. They are five areas to review repeatedly as the flight situation changes.
Example Sentence 1
Before starting his descent into the busy terminal area, he ran through the 5 Ps and realized the weather had shifted enough to warrant a diversion.
Example Sentence 2
When weather began to deteriorate, the pilot paused to recheck the Five Ps and elected to divert.
