Fuel-flow metering exploit

A system working around the fuel-flow meter's sampling gaps — the meter samples the flow rather than integrating it continuously, so flow between samples is not counted.

The regulation caps mass flow and trusts a sampling instrument to measure it.

Straight-line speed. Never established publicly in quantified terms.

A technical directive before the US GP, followed by a confidential FIA settlement announced on 28 February 2020 whose terms were never published. Structurally closed for 2026 by regulating fuel by energy flow rather than mass flow.

The settlement terms are confidential, so the central fact of this case is not verifiable against any primary source. It is in the register labelled unverified rather than omitted, because omitting it would be its own distortion.
