Definition
Physiological conditions or human-factor risks that can degrade a pilot's ability to safely operate an aircraft. Common examples include hypoxia, dehydration, fatigue, stress, illness, medication side effects, alcohol, and the effects of altitude on the body.
Plain English
Things that affect a pilot's body or mind in ways that make flying less safe.
Context Anchor
Seen in risk management discussions, preflight planning, and instructor conversations about whether the pilot is fit to fly.
Derivation
Aero comes from the Greek word for air, and medical comes from the Latin medicus, meaning relating to healing or the body. Together, aeromedical means matters of health and the body as they relate to flying.
Why Pilots Care
These factors can cause sudden loss of judgment or control without obvious warning signs.
Grounding Statement
If something about the pilot’s condition or the flight environment can make the pilot think, see, or control the aircraft less well, it is an aeromedical hazard.
Intuition Check
Do not think of aeromedical hazards only as obvious sickness. In aviation, the term also includes subtle body effects from flying, fatigue, stress, dehydration, or other conditions that can reduce safe performance.
Example Sentence 1
Before each flight, the pilot reviewed the IMSAFE checklist to identify any aeromedical hazards that might affect performance.
Example Sentence 2
Fatigue from poor sleep is one of the most common aeromedical hazards pilots must manage.
