Consumed Fuel Interval Preview

The Consumed Fuel Interval Preview concept places a distance observation beside a fuel-consumed observation and an approximate reported-consumption result. A load planner needs both observations to describe the same interval before their ratio is meaningful. The illustration keeps quantities, basis, declared coverage and source labels close together so the result can be read with its limitations. It uses invented example data throughout.

The two observation cards show a sample twenty kilometres and three litres for the same one-hour UTC interval. Both coverage rows say complete for this interval, and both measurement bases are explicitly operator declared. Separate source chips identify the fictional distance and fuel references and their revisions. The result panel shows approximately fifteen litres per one hundred kilometres, accompanied by the arithmetic used to obtain it and a line noting matching intervals and declared completeness.

An amber operator-reported, unverified notice sits directly under the result. A nearby sentence states that source labels do not verify measurements. These visible qualifications separate useful arithmetic from authenticated sensor evidence, a fleet efficiency rating or a claim of achieved savings. The concept does not substitute purchased or refuelled volume for fuel consumed, and it offers no loading, dispatch or safety decision.

A lower section keeps unknowns visible through three explanatory cards: blank fuel, partial or different intervals, and purchases. A final note distinguishes explicit zero fuel from tiny positive ratios, which are shown below the two-decimal display threshold rather than rounded to zero. The zero example assumes otherwise qualifying observations and positive distance. The footer identifies a read-only calculation with no records saved. The design keeps this small comparison distinct from trip history, source verification and broader load or backhaul planning.
