The portable ELT is waterproof up to how many meters?

• A. 5 meters
• B. 15 meters
• C. 10 meters
• D. 20 meters

Answer: (C)

A portable ELT is built to survive water exposure that can occur during a ditching or rough-water scenario, so its waterproof depth rating is about ensuring it stays sealed and functional even if it ends up submerged. That rating is ten meters, which corresponds to roughly 33 feet. At that depth, the device is protected from water ingress long enough to transmit a distress signal and assist rescuers. If it were only five meters, deeper splashes or occasional submersion in waves could compromise the unit. A rating of fifteen or twenty meters would exceed what's typically needed for aircraft safety gear and would add unnecessary bulk and cost without providing practical benefit in normal operating conditions. So ten meters strikes the right balance between protection and practicality, making the portable ELT reliable in common ditching situations.
