What should be evaluated in the "IM SAFE" checklist?

The "IM SAFE" checklist is a crucial tool for pilots to evaluate their own personal health and readiness before flying. This acronym stands for Illness, Medication, Stress, Alcohol, Fatigue, and Emotion, each representing an aspect of the pilot's well-being that can affect their ability to operate an aircraft safely. By assessing these factors, a pilot can determine whether they are fit to fly and make informed decisions about their readiness.

For instance, if a pilot is experiencing illness or is under the influence of medication, it may impair their performance. Similarly, high stress levels, fatigue, or emotional challenges can detract from a pilot's situational awareness and decision-making abilities. Therefore, the "IM SAFE" checklist is focused on ensuring that the pilot is in optimal condition to handle the responsibilities of flying, making this the correct evaluation for safety.

The focus on personal health distinguishes this checklist from assessments of mechanical status, weather, or flight route, which are external factors but not encompassed within the "IM SAFE" framework.
