If a 'site error' alert is reported by a FU, which tab should be checked to confirm the ECS crew did not introduce obvious data errors?

• A. Tab 14 - Target Display Control
• B. Tab 12 - FP Locations/Boundaries
• C. System/Weapon Control S/I
• D. Tab 1 Page 1

Answer: (B)

The main idea here is verifying data integrity in the engagement data to rule out obvious input errors by the ECS crew. When a site error alert comes from a firing unit, the most direct place to check for incorrect data is where the system stores the coordinates and boundaries that define firing points and engagement limits. The FP Locations/Boundaries page holds these critical inputs, and confirming they are correct helps determine whether the ECS crew introduced obvious data errors.

The Target Display Control tab is about how targets are shown on screens, not about the underlying location data used for engagements. System/Weapon Control S/I relates to overall system status and weapon control functions, not to the data entry for locations and boundaries. Page 1 is a general interface area that doesn’t specifically validate the location data feeding engagement calculations. Hence, FP Locations/Boundaries is the best place to confirm no obvious ECS data-entry errors.
