Operating characteristics
a.
Secures crew member
b.
Supplies life support and
communication connection points
c.
The seat's onboard pitot system
automatically selects operating mode
based on aircraft altitude and airspeed
d.
Ejection
(1) Ejection seat has a 0-0 (airspeed-
altitude) ejection capability
(2) Canopy fragmentation system
synchronized to ejection seat
initiation
(3) Ejection seat sequence same
whether canopy in place or shat-
tered via MDC firing prior to ejec-
tion seat firing
(4) Upon separation of ejection seat
from catapult, electronic se-
quencer controls all events, e.g.,
drogue chute deployment, man/
seat separation, main chute de-
ployment
NOTE: A barostatic release
mechanism is used as a backup in
the event of an electronic se-
quencer failure. It automatically
activates when below 18,000 ft
MSL. The EMERGENCY RE-
STRAINT RELEASE handle is the
manual backup, in the unlikely
event that the barostatic release
mechanism should also fail.
