Wedge-formula approximation for fuel volume in a trimmed tank - used when the tank is not fully level (typical sounding condition).
Formula
$$ V_{wedge} \approx \tfrac{1}{2} L_{wet} \cdot d \cdot B $$Symbol legend
| Symbol | Meaning | Unit | Source |
|---|---|---|---|
| $d$ | Sounding at low end | m | UTI tape |
| $L_{wet}$ | Wetted length along tank | m | trim geometry |
| $B$ | Tank breadth | m | tank GA |
