How Do Burner Combustion Control Systems Work CrossCo
The idea is this the system needs to control fuel and air as "the amount of fuel and air needed for this load". So we convert fuel flow to by multiplying it by a constant. We convert the air flow to by running mass flow through the FAR PWC to get raw then trimming that from the output of the O 2 Trim loop.
