T-45C Weapons System
T-45C WEAPONS SYSTEM
ARMAMENT SYSTEM GENERAL
The armament system provides for the carriage, jettison, sighting, gun firing simulation, and
controlled release of external stores. The air-to-ground (A/G) HUD master mode provides both
manual and Continuously Computed Impact Point (CCIP) sighting for bombs, rockets and simulated
guns. Armament system controls consist of the jettison button, master switch (forward cockpit),
master arm switch/master arm light (aft cockpit), weapons release button and gun trigger, HUD Data
Entry Panel, and MFD stores display. There is no data interface between the weapons station and
the A/G stores display. Weapon quantity and rocket firing mode must be set in by the pilot to match
the weapons load.
ARMAMENT SYSTEM CONTROLS AND INDICATORS
EMERGENCY JETTISON BUTTON
The jettison button (Figure 5) in the forward and aft cockpit when pushed will jettison stores on the
wing pylons simultaneously with weight off wheels. Stores jettison occurs regardless of the selected
weapon or master armament switch position. Centerline external stores will not jettison.
MASTER ARMAMENT AND MASTER ARMAMENT OVERRIDE SWITCH/MASTER ARM LIGHT
The Master Armament switch (Figure 5) is located in the front cockpit. All armament circuits, except
for jettison, are controlled by the master armament switch. With the master armament switch in
SAFE, the armament circuits are deenergized. In ARM the armament circuits are energized and the
MASTER ARM light (Figure 5) is illuminated in the aft cockpit. The Master Armament Override
switch (Figure 5) in the aft cockpit can disable the armament system when placed in the SAFE
position. When in the FORWARD position, the forward cockpit controls the armament system.
WEAPONS RELEASE BUTTON AND GUN TRIGGER
The A/G weapon release button or pickle button (Figure 5) is used to release weapons from the
wing stations. With the master arm switch in ARM and a wing station selected on the stores display,
pressing the button releases a bomb or fires a rocket. The GUN trigger (Figure 5) is used to fire the
simulated gun. With the master arm switch in ARM and GUN selected on the stores display,
squeezing the trigger simulates gun firing.
HUD DATA ENTRY PANEL (DEP)
The DEP (Figure 5) is used to adjust the MIL depression setting, select the HUD master mode, and
enter target height. The MIL depression setting of the depressed sight line is adjusted with the SET
DEP +/- rocker switch, HUD master modes, navigation, air-to-air, and air-to-ground are selected with
the MODE button and target height is entered with the DEP buttons.
