METHOD:
1. Enter bottom right of chart (Fig. 5-7) at 54 psi torque. Move up along
54 psi torque line to 6000 foot pressure altitude curve, move left to
10°C OAT curve, then move down and read specification TOT of
660°C.
2. Compare the specification TOT of 660°C with TOT observed during
flight (650°C for this example). The TOT that was observed is lower
than the specification TOT. If the TOT observed had been higher than
the specification TOT read from the chart, some power deterioration
will have occurred and the performance given in this manual may not
be obtained.
3. When trend check procedures indicate engine power deterioration, re-
fer to the Rolls Royce Operation and Maintenance Manual for correc-
tive action.
