NAVIGATION MENU Abnormal operation (B) 3/40 Blank MCDU screens with amber FAIL annunciator lights, and the red map on the ND indicate that a double FMGC failure has occurred. Here, we will focus on the navigation, so we will consider that all the actions concerning the other systems have been performed. NAVIGATION MENU Abnormal operation (B) 4/40 As the MCDU are no longer available for navigation and nav aid tuning, the only navigation capability remaining is radio aid raw data. For this we need to use the standby nav aid tuning capability of the RMP.

The setting of the other nav aids (frequency, course) is done in the same way. Note that if an ADF receiver is selected, pressing on the BFO key will activate the Beat Frequency Oscillator. Note : when a RMP is used to tune an ILS/DME, the PFD do not display the DME distance.

NAVIGATION MENU Abnormal operation (B) 37/40 NAVIGATION MENU Abnormal operation (B) 38/40 In case of any failure, a message appears on the ND : amber for a radar performance degradation, red when no image is available. The next faulty system is the TCAS. NAVIGATION MENU Abnormal operation (B) 39/40 In case of TCAS failure, a TCAS fault is displayed on the E/WD and TCAS red flags appear on both PFD and ND. Note that there are neither warning light nor aural warning. We will now study the DDRMI flags.
