Those "PVC pipe"-looking tubes on the canopy are actually Cartridge Actuated Devices (CADs) — not plumbing parts, but critical components of the aircraft's emergency systems.
Purpose and Function
Purpose and Function
- These CADs are pyrotechnic charges designed to jettison the canopy during an emergency ejection.
- When activated, they fire small rocket-like charges that push the canopy up and away from the aircraft, clearing the path for the pilot's ejection seat.
- You can spot nozzles at the outboard ends and ignition wires inboard, which are part of the firing mechanism.
- Their cylindrical shape and white exterior resemble PVC tubing, but they’re built from aerospace-grade materials to withstand high stress and heat.
- The design is functional: it houses the explosive cartridge and directs the force safely and effectively.
