of survival kit attachment lugs, negative-g strap, leg restraint lines, and inertia reel straps; firing of the
manual override initiator cartridge; firing of the barostatic release unit; and firing of the parachute
deployment rocket, which deploys the parachute. The ejection seat safe/armed handle automatically
rotates to the SAFE position whenever the manual override handle is actuated.
Pulling the manual override handle automatically rotates the ejection
seat safe/armed handle to the SAFE position, releases the survival kit
attachment lugs and leg restraint lines, and unlocks the inertia reel. If
this is done inflight, the aircrew will be unable to eject.
2.15.3.10 Seat Bucket Position Switch. The seat bucket position switch is on the left side of the seat
bucket, forward of the shoulder harness lock/unlock handle. The forward switch position lowers the
seat bucket, the aft position raises the seat bucket. The center off position, to which the switch is spring
loaded, stops the seat bucket. The maximum vertical travel of the seat bucket is 5 inches. The actuator
should not be operated over 1 minute during any 8 minute period.
2.15.4 Ejection Seat System (F/A-18F). Ejection seats are installed in both cockpits. In addition, a
sequencing system is installed to allow dual ejection initiated from either cockpit or single (aft) seat
ejection initiated from the rear cockpit. A command selector valve is installed in the rear cockpit to
control whether ejection from the rear cockpit is dual or single.
2.15.4.1 EJECTION MODE Handle (F/A-18F). The EJECTION MODE handle is located on the right
side of the main instrument panel in the rear cockpit. The EJECTION MODE handle is used to select
the desired ejection sequence to be initiated from the rear cockpit, or provide for single ejection for solo
flight. Positioning is accomplished by pulling out while turning to the desired position. The SOLO
position requires the use of a collar to hold the handle in that position. To release from AFT
INITIATE, pull then turn clockwise.
NORM
(vertical)
Single rear seat ejection when initiated from the rear cockpit. Dual ejection (rear
seat first) when initiated from the front cockpit.
AFT
INITIATE
(horizontal)
Dual ejection (rear seat first) when initiated from either cockpit.
A1-F18EA-NFM-000
I-2-116 CHANGE 1
SOLO
(45° CCW)
Front seat ejection only when initiated from the front cockpit. Front seat ejection
is immediate. Rear seat ejection only when initiated from the rear seat. Rear seat
ejection is immediate.
· SOLO mode shall NOT be selected when both seats are occupied. If
SOLO mode is selected when both seats are occupied, simultaneous
ejection initiation may result in a collision between seats.
· SOLO mode shall be selected when the aircraft is being flown solo.
Alternate selection when flying solo results in ejection of unoccupied
seat and possible collision with the front cockpit seat.
When selecting NORM or SOLO from AFT INITIATE, the handle must
be pulled before rotation or damage to the command selector valve may
result.
2.15.4.2 SEAT CAUT MODE Switch (F/A-18F). The SEAT CAUT MODE switch is located in the
rear cockpit above the command selector valve. The switch position changes the operation of the CK
SEAT caution for solo or dual flight.
NORM CK SEAT caution is activated by either seat remaining safed. Switch is spring
loaded to this position.
SOLO CK SEAT caution is activated only by the front seat remaining safed. Switch must
be pinned to remain in this position.
2.15.4.3 CK SEAT Caution (F/A-18F). The CK SEAT caution light is located on the caution light
panel, and repeats the DDI CHECK SEAT caution display. The caution is displayed when the right
throttle is at MIL or above, weight is on wheels, and the cockpit ejection seat is not armed with the rear
cockpit NORM/SOLO switch set to SOLO or either ejection seat is not armed with the NORM/SOLO
switch set to NORM.
2.16 EMERGENCY EQUIPMENT
2.16.1 Jettison Systems. The jettison systems consist of the emergency jettison system and the
selective jettison system.
2.16.1.1 Emergency Jettison. Emergency jettison is performed by pushing the EMERG JETT
button with either the LDG GEAR handle UP or with WoffW. When activated, the emergency jettison
system jettisons all stores, launchers, and racks from the BRU-32 racks on the six wing pylon stations
(2, 3, 4, 8, 9, and 10) and the centerline station (6). Emergency jettison is sequential by station pairs:
3 and 9, 2 and 10, 4 and 8, then 6. There is a 100 msec, ±25 msec, delay before the first set of stations
is jettisoned and in between each subsequent set.
