T-45A UJPT, E2-C2, ADV, & IUT Eng-26
Engineering Review
(a) BOTH: actuation of ejection
handle from either cockpit
immediately ejects the aft
seat, followed 0.4 seconds
later by the forward seat
(b) FWD-BOTH/AFT-SELF:
Overlay 1
when initiated by fwd seat, aft
seat fires first, then fwd seat
fires. When initiated from aft
cockpit, ejects only the aft
seat
NOTE: If ejection is initiated
by the FWD seat, FWD firing
circuit is routed through a
0.5-second delay cartridge.
This serves as a backup to
the 0.4-second delay initiator.
(c) SOLO: must have red metal
selector collar and red safety
pin on seat light switch
installed
NOTE: With the selector
Overlay 2
handle in SOLO position, the
0.4-second delay between
fwd and aft ejection is lost.
The SOLO position shall not
be used for a dual flight.
NOTE: SOLO position does
not prevent the aft seat from
ejecting if occupant in aft seat
initiates the ejection
sequence. The 0.4-second
delay is lost, however, and it
is possible for the fwd cockpit
to initiate ejection
simultaneously with the aft
cockpit.
