In the process of seat ejection, multiple components work together to ensure the safety of the pilot. These components include a seat catapult, restraints, an explosive cartridge, pitot tubes, and an onboard central processing unit. Each component plays a crucial role in facilitating a successful ejection process while minimizing the risk of harm to the ejected pilot.

Upon pulling the ejection lever, an electrical signal is transmitted, causing the hatch or canopy overhead to unlock or detach from the aircraft. Simultaneously, the seat catapult is initiated, propelling the seat upwards along the rails. Additionally, an explosive charge is fired beneath the seat, forcefully ejecting the pilot from the aircraft. This sequence of events must occur with precise timing to ensure the pilot’s safety.

Once the pilot is fully ejected and safely away from the aircraft, an onboard rocket motor and stability system engage. These systems adjust the seat’s pitch to prevent the pilot from spinning uncontrollably during their descent. This ensures a stable and controlled trajectory as the pilot descends to the ground.

To determine the appropriate mode of operation, the seat utilizes pitot tubes or seat sequencers to measure airspeed and altitude. The onboard processing unit analyzes these measurements, enabling it to select the optimal mode for the ejection process. These calculations are necessary since higher altitudes, such as 50,000 feet, have lower oxygen levels. The seat must provide additional oxygen to the pilot and allow for a longer free fall to reach lower altitudes safely.

Once the pilot reaches an altitude of 15,000 feet, a parachute is deployed. This parachute ensures a gentle descent and safely delivers the pilot back to the ground, providing a final layer of protection.
