Many of you pick up the fact that the max continuous at altitude is lower that climb and cruise thrust.
My explanation is the fact that if we lose an engine at altitude and use max continuous (probably the only occasion we need mct there)

The remaining engine as to provide the remaining pack a higher pressure, from 31 psi to 42 psi approx.
That putting a lot of strain on an engine gasping for air already. So the demand of air would increase the ITT, so the result of a lower N1 value as altitude increase to maintain the temp in normal value.

Any other explanation

Nick
