Which of the following is a function of the differential pressure controller?

It limits the maximum manifold pressure that can be produced by the turbocharger at full throttle conditions.

It controls all positions of the waste gate except at fully open position.

The differential pressure controller is responsible for controlling the positions of the waste gate to optimize the performance of the turbocharger. Option A is incorrect because it limits the maximum manifold pressure, but this is not a function of the controller. Option C is incorrect because the controller does not control the waste gate after the aircraft has reached its critical altitude. Option D is incorrect because the controller is not responsible for monitoring fuel pressure within the system. Therefore, option B is the correct answer as it accurately describes the function of the differential pressure controller.
