Title: Weapons Malfunctions
Dialogue: There are several types of weapon malfunctions that can occur during fire mission processing. These malfunctions fall into five categories:
Dud Fuze: A dud fuze is a warhead malfunction that will prevent warhead detonation. If a fuze malfunctions before or during the fire mission process, a capital letter "D" will appear in the status line which represents the rocket with the dud fuze.
Misfire: A misfire occurs during a fire sequence when the FCS detects no electrical pulse being generated by the squib igniter. This is a system malfunction. The system will automatically try to fire three times before you see the letter "M.” If a misfire occurs, the FCS will display the "M" prompt on the status line.
PIM Related Failure: PIM related malfunctions occur when the FCS is unable to communicate with the weapons because the PIM is unable to relay data. This system malfunction may or may not cause an FM to abort. If the weapon itself cannot process data from the EU or PIM, then the letter "W" is displayed on the status line.
Weapon Related Malfunction: If, after pressing LCHR LAY, a weapon malfunction occurs, the appropriate fault prompt shall be displayed. A weapon malfunction may be classified as a temperature related malfunction, or a non temperature related malfunction.
If an over temperature malfunction occurs, the prompt MISSILE TEMPERATURE CAUTION OR WEAPON MALFUNCTION WILL BE DISPLAYED.
If a non temperature related malfunction occurs, the prompt WEAPON MALFUNCTION IN LPC 1 OR WEAPON MALFUNCTION IN LPC 2 will be displayed, depending on which GMLA the missile occupies. In either case the crew will follow the troubleshooting instructions as outlined in TM 9-1425-646-10-2.
