Plain English Meaning

A simple personal checklist a pilot runs through before flying to make sure they themselves are fit and ready to fly safely.

Full Definition

A personal preflight self-assessment checklist used by pilots to evaluate their own fitness to fly. Each letter prompts the pilot to honestly check one factor that could impair judgment, perception, or performance: Illness (am I sick?), Medication (am I taking anything that could affect me?), Stress (am I under pressure that could distract me?), Alcohol (have I consumed any recently, and am I within legal and safe limits?), Fatigue (am I rested enough?), and Emotion (am I emotionally stable enough to fly?). If any factor is a concern, the pilot is expected to delay or cancel the flight.
