Which condition is commonly considered a flight disqualifier due to risk of sudden in-flight events?

• A. Seasonal allergies
• B. Myopia
• C. Controlled hypertension
• D. Recent myocardial infarction

Answer: (D)

The main idea here is that a recent myocardial infarction carries a real risk of sudden incapacitation during flight. An MI can trigger another acute coronary event, dangerous heart rhythms, or acute heart failure. In the aviation environment, where immediate medical help isn’t readily available, that risk can’t be managed quickly, so pilots are kept out of flying duties until there’s a stable recovery and proper medical clearance. That combination—recent coronary event plus the danger of abrupt impairment at altitude—makes this condition a classic flight disqualifier. Seasonal allergies and myopia don’t inherently cause sudden, life-threatening incapacitation in flight. Seasonal allergies are typically manageable with medications and don’t pose an abrupt loss of function. Myopia is a refractive error that is corrected with lenses, so vision can be maintained safely. Controlled hypertension is often acceptable if blood pressure is stable and well managed, though uncontrolled hypertension would raise concerns.
