Ejection Flashcards
Identify aircraft in the ADF fleet that are ejection-seat equipped
Fast Jets High performance aircraft PC- 9 - Martin baker Mk CH 11A PC - 21 - Martin Baker Mk CH16C Hawk - Martin baker Mk 10L F/A-18 - SJU-9/10 - modified MB Mk10 F-35 - US16E (MB Mk16
Describe a generic ejection sequence for a rocket powered ejection seat
Correct position Pull ejection handle, harness retracts Seat up rails, drogue gun fires Drogue ‘chute stabilises seat If below 10000ft main chute deploys, Pilot restraints released Seat falls away, chute fully developed
Identify the components and features of a generic ejection seat
Canopy breaker Head box BTRU Ejection gun Ejection handle PSP Rocket pack Boyangs
Demonstrate the correct posture and preparation fro per-meditated ejection
Looking straight ahead
Back against seat
Leg out front so no gap under thighs
Hands on ejection handle
Describe factor that influence the effects of ejection on the body
Unprepared Poor positioning Airspeed Unusual altitude Occupant weight Dynamic overshoot
Describe the effects on the body and injuries that may occur during ejection
8% fatal
36% vertebral factors
76% bruises and abrasions
Canopy separation
- through canopy= neck and head injury
- MDC - Molten splatter, burns, ocular FB, tattooing
Separation phase
- wind blast - limb flail, # & dislocations, pulmonary injury, Loss of ALSE
- Dynamic overshoot - Femoral #
- Acceleration - vertebral, mandible, sternal # and neck injury
In seat phase
- high altitude: hypoxia, thermal injury, decompression illness, barotrauma
Parachute descent phase
- sudden deceleration, 8G at 10000ft
- contact with risers
- neck injury
Landing phase
- Lower limb injury
- impaling injuries
- cuts and abrasions
- burns
- drowning
Describe the medical and administrative Mx of aircrew post- ejection
Actions after landing
- minimise movement
- expect a fracture somewhere
- await medical assistance
- Standard survival consideration apply
Retrieval of ejectees- apply EMST principles
- Primary survey DRABC
- Cervical, thoracic, lumbar spine protection
- Winch in stretcher
- Monitor, repeat 1 & 2rd survey
- preserve/quarantine all ALSE
Tx of vertebral injuries
- Initial: minimise movement, pain relief, Imaging
- Ongoing: TMUFF/UAMECR, Mobilise early with Physio, Back to flying expected after 3 months
MDC injury Mx
- IX: imaging, USS, Opthalmology review
- Prevention: visors down, eyes closed for canopy closure
IX
- plain full spine anterior/posterior and lateral films for all ejectees.
- face/skull films for MDC splatter
- Bloods, urine as per PM185
- CT, MRI, bone scan as indicated
The correct ejection posture includes A. Elbows tucked in B. Feet on the floor C. Head forward D. One hand on the ejection handle
A. Elbow tucked in
Correct parachute landing fall technique
5 points of contact
- balls of feet
- side of one leg
- thigh
- hip
- back of shoulder
Bend the knees, heels, together..
How to minimise risk of ejection injury
Make ejection decision on the ground Premeditated and prepared Wings level, upward vector Visors down Restraints tight Ejection posture Parachute landing fall
