During AED preflight, which indicator confirms the unit is powered and ready?

• A. Black case
• B. Secure in proper location
• C. Accessory kit attached with plastic seal
• D. Blinking green light next to on/off button

Answer: (D)

The main thing being tested is how you verify that the AED is actually powered and ready for use during preflight. The indicator that confirms this is a blinking green light next to the on/off button. That light shows the unit is powered on and in a ready state, typically signaling sufficient battery and proper operation. The other checks—black case, securing in the correct location, or the accessory kit seal—tell you the device is present and stored correctly, but they don’t indicate whether the unit is powered and ready.
