Max efficiency altitude for a Jet Engine
Ignoring pressurisation problems, (and coffin corner aerodynamic issues) what would be the maximum altitude for efficiency for a jet aircraft (say 744).
As I understand it, as altitude increases, the increasing difference between the EAS and the TAS mean that the aircraft can travel further (ie more efficient in this context). When would this stop? At the tropopause when the temperature becomes constant?

Those who restrain desire do so because theirs is weak enough to be restrained.
