Autopilot 1 and autothrust are engaged. Let抯 first review the ECAM ELEC page. ELECTRICAL MENU Abnormal operation (B) 5/34 As you already know, AC bus 1 is normally supplying: ?AC ESS bus and ?DC bus 1 which in turn feeds DC ESS bus.

ELECTRICAL MENU Abnormal operation (B) 7/34 As you notice, the first consequence is that the Captain抯 PFD, ND and E/WD are blank. The SOP recommend, in such a case, that the First Officer should fly the aircraft while the Captain does the ECAM action.

ELECTRICAL MENU Abnormal operation (B) 18/34 The line concerning the autopilot has disappeared. We can also see that the AC bus 1 fault has led to AC and DC ESS bus failures. ELECTRICAL MENU Abnormal operation (B) 19/34 The first line in the procedure shows us how to recover the essential buses. You will have to switch the 揻eed?of AC ESS bus from AC bus 1 to AC bus 2. The PF will ask you to perform the ECAM actions. ELECTRICAL MENU Abnormal operation (B) 20/34 Notice on the ELEC panel, the FAULT light on the AC ESS FEED pb sw. PeerrffoorrmECAMaaccttiioonn..

ELECTRICAL MENU Abnormal operation (B) 23/34 The Captain抯 PFD and ND are recovered after a few seconds. The E/WD is back on the upper ECAM. The ECAM ELEC page is automatically displayed on the lower ECAM. ELECTRICAL MENU Abnormal operation (B) 24/34 You can see on the ECAM ELEC page that both essential buses are now recovered. For that, AC bus 2 is now supplying the AC ESS bus which in turn, via the ESS TR, supplies the DC ESS bus.

ELECTRICAL MENU Abnormal operation (B) 26/34 On the ELEC panel, the FAULT light on the AC ESS FEED pb sw has been replaced by a white ALTN light. This means that the AC ESS bus is supplied by its alternate source, AC bus 2. ELECTRICAL MENU Abnormal operation (B) 27/34 Notice that DC BAT and DC 1 buses are automatically supplied by DC bus 2 after a short delay. ELECTRICAL MENU Abnormal operation (B) 28/34 The other steps of the procedure have disappeared with the recovery of the essential buses. ELECTRICAL MENU Abnormal operation (B) 29/34 The only bus which remains unpowered is AC bus 1.
