During the ejection sequence, the ____________ ignites as the seat reaches the top of the rails.

• A. rocket motor
• B. manifold cartridge
• C. rocket motor and the CFS
• D. manifold cartridge and the rocket motor

Answer: (A)

The main thrust to escape is provided at that moment by the rocket motor. As the seat reaches the top of the rails, the rocket motor ignites to push the seat and occupant out and away from the aircraft, ensuring a clear path from the airframe. The manifold cartridge and the control firing system are involved earlier in the sequence to prepare and arm the system, but the ignition that occurs at the top-of-rails point is the rocket motor.
