CLAAS 7727h: Engine Power Reduction Due to High Mixed Air Temperature

The engine calculator detects that the temperature of the mixed air is averagely high. As a result, the engine power is reduced by 5% per minute until it reaches 80% of its nominal power. The power recovery rate is 5% per minute once the temperature returns to normal.
