Abstract
A normal acceleration schedule limits the rate of engine acceleration A second acceleration schedule permits a higher acceleration, which causes higher thermal stress in the hot engine parts. The higher schedule is enabled only during a landing approach, thus limiting the number of such stress cycles, while achieving improved performance for the selected mode.
