In what situation is an active recovery device not necessary in a high-power rocket?

An active recovery device is responsible for ensuring that a rocket returns safely to the ground after its flight, often employing mechanisms such as parachutes or other controlled descent systems. In the scenario where a rocket employs a passive recovery system, the need for an active recovery device is eliminated.

A passive recovery system allows the rocket to descend without additional mechanisms that actively control its descent. For instance, some rockets use gliding fins or other aerodynamic features that enable a slow descent without the need for active deployment of recovery devices. As a result, in situations where a passive recovery system is effectively in place, an active recovery device would not be necessary, as the rocket's descent is managed by its design and natural aerodynamics.

Other scenarios, such as high winds, the size of the rocket, or launching at high altitudes, may still involve risks that necessitate an active recovery device to ensure safe landings.
