Plain English Meaning
A simple four-part check pilots run through before flying to spot anything that could make the trip risky -- their own state, the plane, the conditions outside, and any pressure pushing them to fly when they shouldn't.
Full Definition
A personal risk-assessment tool used by pilots before and during a flight to identify hazards in four categories: the Pilot (fitness, currency, experience), the Aircraft (airworthiness, equipment, fuel), the enVironment (weather, terrain, airspace, time of day), and External pressures (schedule, passengers, get-there-itis). The pilot reviews each category, identifies risks, and decides whether they can be eliminated, reduced, or whether the flight should be modified or cancelled.
Context Anchor
Seen in preflight planning, flight instructor discussions, and aeronautical decision-making lessons.
Derivation
PAVE is an acronym built from the first letter of each risk category: Pilot, Aircraft, enVironment, External pressures. The 'V' is taken from the middle of 'enVironment' so the acronym spells a real word, which makes it easier to remember.
Why Pilots Care
Systematically uncovers risks that contribute to many general aviation accidents, allowing pilots to make informed go/no-go decisions and reduce the chance of an incident.
Analogy
Like a driver checking their own alertness, the car’s condition, the road and weather, and whether they really need to make the trip before heading out on a long drive.
Intuition Check
Do not think of the PAVE checklist as a box-checking paperwork item. It is a decision tool for asking whether the flight still makes sense under the actual conditions.
Example Sentence 1
Before the cross-country flight, she ran through the PAVE checklist and decided to delay departure after realizing she had only slept four hours.
Example Sentence 2
During the lesson the instructor had the student apply the PAVE checklist to a scenario involving fatigue and an approaching front.
