Weapon Building
Human Factors - The weapon was assembled correctly with serviceable parts, if parts are missing the weapon will not function correctly
System Mismatch - The correct parts weren't available at the start of the build. The team were less than adequately trained
-

-
Loading Manuals
Human Factors - Long and complex instructions, the load team could skip important steps within the procedure and the weapon is loaded incorrectly
System Mismatch - Reading long and arduous instructions may give rise to violations and the use of memory based execution of the task
Human Factors - The reader not realising the text is out of date, incorrect information used to load and the weapon is loaded incorrectly and may not function correctly
System Mismatch - Work stress and the emphasis on time restraints are a large distraction. It is also human nature to assume that since the document was correct before, it is still the case
Human Factors - Loading manual not taken out or forgotten, the load team rely upon memory and forget critical steps, creating an unsafe weapon
System Mismatch - Time pressure, the layout of tooling required in the workshop and attention to required tooling
Weapon Safety Devices
Human Factors - The safety devices were not fitted correctly, leaving the weapon in an unsafe state
System Mismatch - Design of the safety devices may allow for them to snag and be removed unbeknown to the load team. Work time restraints could also distract that they are missing or incorrectly fitted
Human Factors - The safety devices were left fitted and flown with, the weapon if released will not function
System Mismatch - Distraction or the safety devices red flags were not prominently displayed could allow this to missed
-
ASLT Servicing Personnel
Human Factors - Required to be trained and authorised, if the ASLT is not serviced correctly it could potentially break or operate as unintended
System Mismatch - Workplace design that only allows partial completion of the servicing, human nature to take shortcuts
-

Firing Circuit
-
Human Factors - The incorrect weapon firing button pressed, the weapon is not released or an incorrect weapon was released/fired
System Mismatch - The stress of the situation and the possible button layout could be the contributing factors
Human Factors - Incorrect firing method selected. The weapon is released in a high drag configuration and lands short of the intended target
System Mismatch - Display design, of the weapon management screen with abbreviated program settings can make it difficult to select especially whilst getting to the mission area
Target Acquisition
Human Factors - Incorrectly reading the screen, the incorrect target may be selected
System Mismatch - The symbology of the target screen is difficult to distinguish with a lot of data displayed at one time, giving rise to sensory overload. The pilot having to designate a target using the small buttons on the aircraft throttle could be poor design
Communication system
Human Factors - Correct channels need to be loaded by maintenance personnel, if the incorrect channels are loaded the pilot will not be able to communicate with headquarters, other aircraft or the Aircraft Control Tower
-
Human Factors - Communication system needs to be serviced correctly, if not serviced correctly the system may fail at any time
System Mismatch - Poor procedures for the upkeep of the system. Time restraint leading to shortcuts taken in servicing.
Human Factors - Pilot and Headquarters have to transmit and receive the correct channel, or they may not be able to give authority to release the weapon
System Mismatch - Human error and not selecting the correct channel. Design of the communications panel, with the small LCD screen and rotary switch make it difficult to use
