PROPERTIES OF THE ATMOSPHERE (Text Chapter 2)

What he did was to run one engine at idle, and the other at high power, thus reducing overall TSFC (fuel flow). In other words, to get total thrust T, instead of operating each engine at thrust T/2, he operated one engine at very low thrust and the other at high thrust. Figure 6.4.
