Which of the following is NOT a type of recovery?

The concept of recovery in aviation refers to various methods that can be employed to recover an aircraft that is in distress or has encountered difficulties during flight operations. Among the options listed, cooperative recovery is not recognized as a distinct type of recovery approach in aviation.

Self recovery typically involves the pilot taking measures to regain control of the aircraft independently, such as executing protocols to stabilize flight or navigate back to safety after encountering issues. Dedicated recovery, on the other hand, refers to a scenario where specific resources or teams are assembled and prepared with the singular purpose of recovering an aircraft in trouble, often employing specialized equipment or techniques to ensure a successful outcome. Delayed recovery may involve a planned wait before action is taken to recover the aircraft, possibly due to conditions that need to be assessed before proceeding.

In contrast, cooperative recovery might suggest a scenario where multiple entities work together towards recovery, but this term is not widely acknowledged or defined in standard aviation recovery procedures. Therefore, this makes it not a recognized type of recovery, thus aligning with the notion that cooperative recovery is the correct choice as the option that does not fit in the context of established recovery types within aviation.
