Which component of the CFS allows for the fracturing system activation for each individual canopy transparency?

The internal CFS handle is the correct component that allows for the activation of the fracturing system for each individual canopy transparency. This handle is designed to enable the crew member to initiate the canopy fracturing sequence from inside the cockpit, ensuring that each transparency can be easily and independently activated without the need to interact with external mechanisms. This is particularly important in emergencies when rapid egress is necessary, allowing the pilot to focus on safely exiting the aircraft.

Other components mentioned have different roles. The CFS acceptor assembly interacts with the fracture system but does not serve as the direct activation point for individual transparency. Optical detonators are responsible for the actual fracturing process but require activation from the handle. The external CFS handle, while also a means of activation, is not used for each individual transparency in the same way that the internal handle is, as it is designed for use in situations where external access is necessary.
