1.
When PUSH TO JETT is pressed in either cockpit,
28 VDC from essential services bus electrically fires
twin pyrotechnic cartridges in each pylon, ejecting
the store carried on that station
2.
When aircraft is on ground, nose and main gear
WOW relays break the 28 VDC path, preventing
inadvertent jettisoning of stores
NOTE: The T-45C has provisions for carrying a
baggage container on a center pylon which is not
electrically connected; therefore, the baggage
container cannot be jettisoned.
