CommuteAir Flight Attendant Ground Training Emergency Equipment Practice Test

The feature being tested is the tether strap on an Infant Life Vest. This strap is designed to secure the infant to an accompanying adult or to keep the vest from sliding off the caregiver during a ditching or in rough water, which is essential for keeping the infant attached to someone who can help. The other options—GPS beacon, water-activated locator light, and reflective tape—are not standard, defining features of an infant vest in the typical airline equipment set; while some equipment may include locator traces or reflectivity, the tether strap is the specific feature that directly relates to safely restraining an infant with a caregiver.
