EJECTION CONSIDERATIONS
When do you eject?
“...The timely ejection option, once selected
becomes irrevocable. There must be no compromise of the
principle of life through ejection by delaying the ejection
decision too long...”
9 out of 12 ejection fatalities are out of the envelope.

MANDATORY EJECTION CONDITIONS
• Ejection may be necessary as result of fire, engine failure, structural
damage, midair collision, or when the aircraft becomes uncontrollable.

EJECTION SEAT SEPARATOR ROCKET
“Ear Burner” Seat Separator Rocket
• Provides positive seat separation.
• Rocket thrust rotates and propels
seat away to minimize probability of
pilot/seat collision.
• Rocket fires 0.5 seconds after
ejection initiated.
• Separator rocket armed by seat
rocket catapult as seat leaves the
rails.

SEQUENCE
• Pull upper or lower handle.
• Canopy jettisons.
• Inertia reel power retracts.
• Aft seat fires first to prevent blast injury from front seat.
• 0.55 seconds later, front seat fires.
• Emergency oxygen and beacon actuated.
• 0.3 second delay cartridge fires harness release.
• Seat/man separation at 0.5 seconds
• Ripcord pins 0.75 seconds.

SEAT SWITCH
• Switch located outboard, right
console.
• The seat is electrically adjusted in
the vertical plane by movement of
the switch to the UP or DOWN
position.
10
Advanced Training Systems
International
SHOULDER HARNESS LOCK LEVER
• Located on the left side of the seat
bucket.
• Locks the inertial reel.
• Shoulder harness will not extend
when lever in locked position.
• The unlocked position allows the
harness to extend and retract as pilot
moves (free movement).
• Inertial reel will lock automatically
if aircraft subjected to 2.5g
deceleration.
11

EMERGENCY RESTRAINT RELEASE HANDLE
Labeled
HARNESS RELEASE
• Mounted on the right side of the
seat.
• Handle latch must be squeezed to
pull handle and release the
barometric parachute opener
lanyard, shoulder harness and seat
belt attachments.
• Allows the pilot to leave the cockpit
with the parachute and survival kit
still attached to the integrated torso
harness.
12
Advanced Training Systems

FACE CURTAIN
• Housed in the headrest structure
with the handle protruding.
• Screens the face from the wind blast
during ejection.
• Handle serves as a control for
ejecting the seat and aids in
supporting and positioning the pilot
during ejection.
13
Advanced Training Systems
International
LOWER EJECTION HANDLE
• Located on the forward side of the
ejection seat between the pilot’s
legs.
• Lower handle used to initiate the
ejection sequence when the face
curtain is not desirable or possible.
• A pull force of not more than 60
pounds is required to initiate ejection
with lower handle.
14
Advanced Training Systems
International
HEADKNOCKER
• EJECTION CONTROL SAFETY
HANDLE located between two
rubber pads on the upper forward
area of headrest.
• Functions as an ejection seat safety
lock when in the down position.
• Safety lock must be manually
depressed to raise headknocker to
the up position.
15
Advanced Training Systems
International
EJECTION SEAT CONTROL SELECTOR
“UP FOR SOLO, DOWN FOR DUAL”
• Located in the forward cockpit on
the bulkhead aft of the left console.
• Two position valve set prior to
flight.
• UP position: Front seat pilot can
eject both seats. Rear seat pilot can
eject rear seat only.
• DOWN position: Both seats ejected
regardless of which pilot initiates
ejection.
16

NES-12 PARACHUTE PACK
• 28’ flat circular canopy.
• Ballistic spreader gun opens chute
after 0.75 second delay as long as
crewman below 14,000’.
• External pilot chute orients pilot
position for effective deployment of
parachute canopy.
• 4-line release system provides
parachute stabilization with minimal
parachute steering capabilities.
17
Advanced Training Systems
International
EJECTION SEAT STABILIZATION (DART)
• Counteracts the adverse effects of
aerodynamics and seat system center
of gravity.
• Provides consistent and predictable
trajectory during the rocket burning
phase.
• System installed on the underside of
the seat bucket.
18

RSSK-8 SURVIVAL KIT
• Rigid Seat Survival Kit.
• Contains emergency oxygen supply,
survival equipment, and emergency
beacon.

MANUAL BAILOUT PROCEDURES
1. Pull green ring on seat pan for
emergency oxygen.
2. Disconnect console oxygen and
antiblackout hose.
3. Select RAM.
4. Jettison canopy.
5. Pull emergency restraint release
handle.
6. Lean forward to clear parachute
past headset.
7. Trim aircraft nose down.
8. Apply back pressure to stick.
9. Position arms against body and let
stick snap forward.
10. When clear of aircraft and below
approximately 14,000’, pull
parachute ripcord.
11. As time permits, perform postejection procedures.

POST EJECTION CONSIDERATIONS
• If either the harness release or automatic barometric PARACHUTE
actuator cartridge fails to function properly, automatic SEAT separation
and/or PARACHUTE deployment may not occur.
• Therefore, during any low altitude ejection, the pilot should attempt to
“BEAT THE SEAT” by manually pulling the EMERGENCY
RESTRAINT RELEASE HANDLE and then the PARACHUTE
RIPCORD immediately after ejection.
• High altitude.
• Low altitude.
• Over land.
IROK
• Over water.

GROUND EGRESS - WITHOUT PARACHUTE
When electing to exit the aircraft without PARACHUTE and SURVIVAL
KIT, the following procedures should be followed:
1. Pull CANOPY JETTISON HANDLE.
2. Unfasten the four (two upper Koch fittings, two lower)
PARACHUTE HARNESS FITTINGS.
3. Disconnect OXYGEN HOSE
4. If time permits, safety the ejection controls by
pulling the SAFETY HANDLE on the pilot
headrest to the “DOWN” position. This will
preclude inadvertent ejection of the SEAT.
5. Exit from aircraft.

REVIEW
• 0/0 Seat (study seat envelope charts).
• High altitude (time permitting) - controlled ejection procedures with use
of face curtain.
• Low altitude - immediate ejection with use of lower handle, “try and
beat the seat.”
• Body positioning critical to minimizing injury.
• IROK
• Decide on preferred ground egress method.
