Central Warning/Caution/Advisory and Annunciator System (CWS)

The Central Warning/Caution/Advisory and Annunciator System is responsible for advising the pilot of any system issues that need to be brought to his or her attention during operations. Please note that the CWS system has been customised slightly to meet limitations with Microsoft Flight simulator and as such should not be taken as exact to the real aircraft.
