There appears to be two digital displays per gauge as well as an analogue display. What was the peak consumption per engine, and why two digital displays on each gauge?
To refresh memories, here's the only, not very helpful, entry in the Flying Manual that I've found.
My guess is that the upper digital counter indicates the proportion of the fuel flow that goes to the reheat but it's only a guess.
Sorry, I have no figure for the max fuel consumption.
The '35 tonnes/hr' limit on the indicator is obviously beyond the upper limit, like the speedo on a car.....
But yes, fuel consumption at takeoff with reheat was horrendous, and would have emptied all the tanks in an hour or less.
