What does the acronym AED stand for in aviation safety equipment?

• A. Automatic External Defibrillator
• B. Automated External Defibrillator
• C. Allergen Exposure Device
• D. Aircraft Emergency Detector

Answer: (A)

AED stands for Automated External Defibrillator. This portable device analyzes a person’s heart rhythm and, if needed, delivers a shock to restore a normal rhythm. The key idea is that the device performs the rhythm analysis automatically and is used on someone outside the body. In aviation safety gear, AEDs are carried for in‑flight medical emergencies and are designed to be user-friendly for quick, effective use. The term Automated External Defibrillator is the standard phrasing; using Automatic External Defibrillator isn’t the commonly accepted terminology. The other options refer to things unrelated to defibrillation (like allergens or detectors), so they don’t fit.
