The fuel and air setpoints are calculated with regard to the maximum load difference.

Load increase

In case of a load increase, the load setpoint of the air channels is increased first, then the load setpoint of the fuel channels.

Load reduction

In case of a load reduction, the fuel channel load setpoint is reduced first, then the load setpoint of the air channels.

This ensures that there is always an excess of air in the event of significant load changes.
