What is an "automatic activation device"?
An automatic activation device is a mechanism that triggers an action without needing manual control. It works by sensing specific conditions or inputs, such as speed, altitude, or pressure, and then automatically performs a task, like opening a parachute or releasing a target. These devices are commonly used in activities where precise timing or safety is essential, helping to ensure that actions occur at the correct moment or in response to certain changes.
Examples
The AAD saved the skydiver by deploying the reserve parachute when needed.
