What Is A Typical Emergency Escape System Sequence?

In-Flight Emergency Escape with Seat Ejection

  1. Aircrew pulls ejection handle to initiate ejection sequence Mechanical Pull Initiator, Pressure Cartridge, Detonator
  2. Ejection seat and canopy removal systems sequenced in proper order & timing
  3. Canopy fractured or jettisoned
  4. Seat ejects aircrew member from cockpit Catapult Pressure Cartridge Initiator, Rocket Motor Igniter
  5. Seat sequences drogue parachute deployment and release at correct altitude and speed Drogue Severance Cutter
  6. Aircrew Recovery Parachute deploys and aircrew seat restraints release Pressure Cartridge, Actuator, Pin Puller
  7. Parachute blossoms, providing maximum deceleration of aircrew Reefing Line Cutter
  8. Survival kit deploys below aircrew prior to landing by severing a cord Reefing Line Cutter
  9. Aircrew lands successfully, surviving a catastrophic event

Ground Emergency Egress

  1. Rotate then pull / push to activate the CFS / TRS initiation sequence Arm Fire Initiator, ETLs, Acceptor, Donor Manifold Connector, FLSC, MDC, XTA, Initiation Manifold
  2. Canopy fractured or jettisoned
  3. Aircrew successfully evacuates aircraft on the ground
