No Oldlae, you are making an assumption. Nowhere in the report does it say that the fuel flow did not increase. What it says is that "the fuel
metering valves on both engines correctly moved to then fully open position to schedule an increase in fuel flow." You are making the causal assumption that since this occurred, and the engine did not respond, then the increased fuel flow did not occur.
Can't schedule fuel to the injun when there ain't any in the tanks.
