What is the main purpose of removers (cartridge-actuated devices)?

The main purpose of removers, or cartridge-actuated devices, is to jettison the aircraft canopy. These devices are designed to rapidly expel the canopy from the aircraft in emergencies, allowing for faster egress of pilots or crew members. The quick removal of the canopy is crucial during situations where immediate evacuation is necessary, such as in the event of a crash or fire.

Cartridge-actuated devices utilize explosive charges to create the necessary forces to remove the canopy safely and efficiently without impeding the pilot's escape route. By ensuring that the canopy is removed swiftly, these devices help to enhance the chances of survival for those onboard the aircraft.

While other options relate to aircraft operations, they do not accurately reflect the specific function of removers. Enhancing flight speed, pushing the aircraft into the sky, or stabilizing the aircraft in flight are not roles of cartridge-actuated devices; rather, they are functions related to various other aircraft systems and mechanisms.
