Linear interpolation for tabular firing table data and safety calculations.
Use this calculator when your target value falls between two entries in a firing table. Enter the two known reference points from the table and your target value to find the interpolated result.
If your firing table shows Elevation 450 mils at Range 3000m and Elevation 500 mils at Range 3500m, and you need the elevation for Range 3200m:
Range → Quadrant Elevation (QE)
Range → Time (seconds)
Range → Fuze Time/VT Setting
Range → Drift Correction (mils)
