ELT Checks are performed how often?

• A. Checked every 12 months or half of battery used, or 1 hr continued use
• B. Only during annual inspections
• C. Every 24 months
• D. On demand by the pilot

Answer: (A)

ELT checks ensure the emergency locator transmitter will function when needed. They are performed at least every 12 calendar months, and sooner if the battery has been used for half of its rated life or after one hour of continuous use, whichever comes first. This arrangement keeps the unit reliable by monitoring battery health and limiting unnecessary wear from frequent testing. Other options don’t fit because checks aren’t only during annual inspections, 24 months is too long, and checks on demand by the pilot don’t meet the maintenance requirement.
