Ejection
a.
Ejection seat has 0-0 (airspeed-altitude) ejection
capability, electronic sequencer adjusts to
altitude and airspeed requirements
NOTE: Assumes no rate of descent and
wings-level attitude, nose on horizon (zero rate
of descent, zero rate of roll, and zero rate of
pitch).
b.
Assumes pilot falls within the weight limits
established for this ejection seat. (Prior to
Aircrew Systems Change 646 installation)
WARNING: During ejection seat development
and testing, the SJU-17V 5/A and SJU 17(V)
6/A were qualified for use by aviators with nude
weights from 136 lbs. to 212 lbs. Operation of
the seat by personnel not within these
parameters subjects the occupant to increased
risk of injury.
(1) Less than 136 lbs nude:
At greater risk from higher catapult
accelerations, seat instability, and opening
shock
(2) Greater than 213 lbs nude:
At greater risk from insufficient altitude for
parachute full inflation at low altitudes and may
not attain sufficient altitude to clear the
aircraft's tail structure
With Aircrew Systems Change 646 (p3I
c.
installed), a new catapult cartridge, with a
choked exit and new rocket fuel propellant,
provides improved performance under imposed
"g" conditions which accommodates aircrew
