Why do you send direction to the FDC?

• A. To orient the FDC to the observer's view of the target
• B. To confirm target location in the grid
• C. To request a different mission type
• D. To update the OT factor

Answer: (A)

The main idea is that you orient the FDC to what you’re seeing. By sending direction, you set the FDC’s reference to the observer’s view of the target, so the FDC can align its azimuth readings with the target’s line of sight. This lets the FDC translate your sighted target into the correct firing data (deflection and elevation) and ensures the guns are aimed along the same line you’re observing. It isn’t about confirming grid coordinates, requesting a different mission type, or updating the OT factor, which are handled through other information or procedures.
