100. T-45C WEAPONS SYSTEM INTRODUCTION
101. T-45C ARMAMENT SYSTEM - GENERAL
The armament system provides for the carriage, jettison, sighting, gun firing simulation, and
controlled release of external stores. Armament system controls consist of the jettison button,
master armament switch (forward cockpit), master arm override switch/master arm light (aft
cockpit), weapons release button and gun trigger, Data Entry Panel, MFD stores display, and the
air-to-ground (A/G) T-45 mode button which provides both Manual (MAN) and Continuously
Computed Impact Point (CCIP) delivery mode sighting for bombs, rockets and simulated guns.
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.
102. T-45C ARMAMENT SYSTEM CONTROLS AND INDICATORS
Emergency Jettison Button
The jettison button (Figure 1-1) 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 1-1) 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 de-energized. In MASTER ARM, the
armament circuits are energized and the MASTER ARM light (Figure 1-1) is illuminated in the
aft cockpit.
The Master Armament Override switch (Figure 1-1) in the aft cockpit is a solenoid type toggle
switch which is energized when the front cockpit Master Armament Switch is selected to ARM.
The Override switch has two positions: FORWARD and SAFE. This is a safety switch that can
disable the armament system when placed in the SAFE (down) position, preventing an
undesirable weapons release. When the front cockpit Master Arm Switch is placed to SAFE, the
Master Override Switch is de-energized, allowing the spring loaded override switch to return to
the up or FORWARD position. The Master Armament Override Switch can also be manually
switched back to the FORWARD position. When in the FORWARD position, the forward
cockpit controls the armament system.
