Engine failure during a derated takeoff

[Goldenrivett]

Hi de facto,

Basic indeed.NO

Please explain how you can exceed a fixed derate thrust setting by pulling the thrust levers back to Climb Power.

When Less is More | Flight Safety Foundation
"Fixed derate thrust settings are lower than the maximum flat-rated thrust setting for the engine. The CFM56-7B27, for example, has a maximum thrust rating of 27,300 lb (121 kN), with optional fixed derates at 22,000 lb (98 kN), 24,000 lb (107 kN) and 26,000 lb (116 kN). These settings are pre-programmed in the FMC and, if allowed by the operator, can be selected by the pilot when conditions permit."
