IMSAFE Checklist

A personal fitness self-assessment that pilots should perform before every flight: Illness (Am I sick?), Medication (Am I taking anything that could impair me?), Stress (Am I under psychological pressure?), Alcohol (Have I been drinking within the last 8 hours or am I still under the influence?), Fatigue (Am I well-rested?), and Emotion (Am I emotionally upset?). If the answer to any question raises concern, the pilot should consider not flying.
