ELECTRICAL MENU Abnormal operation (C) 1/54 ELECTRICAL MENU Abnormal operation (C) 2/54 We will now study the ELECTRICAL EMERGENCY CONFIGURATION. As there are a lot of events which happen at the same time in the aircraft, we will present them in a sequential order. Let’s assume we are in flight and no previous faults have occurred. Click on the forward arrow to activate the failure. ELECTRICAL MENU Abnormal operation (C) 3/54 As you can see, the first consequence is that the power supply for the First officer’s PFD and ND, the Captain’s ND and the lower ECAM is lost. The SOP recommend, in such a case, that the Captain will fly the aircraft while the First Officer does the ECAM action.

ELECTRICAL MENU Abnormal operation (C) 12/54 Observe that the RAT & EMER GEN light has disappeared. The EMER GEN is now running and supplying the system. Notice that with the EMER GEN on line, the power supply to the Captain’s ND has been restored. ELECTRICAL MENU Abnormal operation (C) 13/54 On the E/WD, you can read that the autopilot has disengaged. Let’s deal with this, first. To continue the procedure, you have to clear this line.

Noo,, pprreessss eeiitthheerr CLLR kkeeyy.. ELECTRICAL MENU Abnormal operation (C) 16/54 Read the title of the failure. The red EMER CONFIG title means that you are in an ELECTRICAL EMERGENCY CONFIGURATION. ELECTRICAL MENU Abnormal operation (C) 17/54 The red message LAND ASAP recommends to land as soon as possible. ELECTRICAL MENU Abnormal operation (C) 18/54 Observe that, you have to maintain a minimum speed when the RAT is extended. CAUTION Below this minimum speed, the RAT will stall leading to the aircraft being supplied by batteries only. The PF will ask you to perform the ECAM actions. ELECTRICAL MENU Abnormal operation (C) 19/54 You will try to reset the generators. Here, this will be done for you. ELECTRICAL MENU Abnormal operation (C) 20/54 The reset of the generators has not been successful. Before continuing with the procedure, let’s look at how to access an ECAM page when the lower ECAM is not available. ELECTRICAL MENU Abnormal operation (C) 21/54 An ECAM page can be called up on the upper ECAM by pressing and holding its associated pb sw on the ECAM control panel.

An ECAM page can be called up on the upper ECAM by pressing and holding its associated pb sw on the ECAM control panel. ELECTRICAL MENU Abnormal operation (C) 24/54 The page is displayed on the upper ECAM as long as the associated key is maintained pressed. On the ECAM ELEC page, note that the EMER GEN supplies the AC ESS bus and, via the ESS TR, the DC ESS bus. ELECTRICAL MENU Abnormal operation (C) 25/54 As soon as the ECP pb sw is released, the E/WD is displayed on the upper display. ELECTRICAL MENU Abnormal operation (C) 26/54 As the previous reset of the generators was not successful, we will carry on with the procedure. Coonnttiinnuuee ECAMaaccttiioonn..

ELECTRICAL MENU Abnormal operation (C) 28/54 As the previous reset of the generators was not successful, we will carry on with the procedure. Noo,, pprreessss tthhee BUS TTIIE ppbb ssw.. ELECTRICAL MENU Abnormal operation (C) 29/54 The BUS TIE pb sw in the OFF position segregates the two sides of the system. By doing this, a short circuit can be isolated and might give you the possibility to reset one generator. The procedure asks you to try to reset the generators again. Here, this will be done for you. ELECTRICAL MENU Abnormal operation (C) 30/54 Again, the reset of the generators has not been successful. As the next steps concern other systems, we will stop here and study the indications on the right side of the E/WD. ELECTRICAL MENU Abnormal operation (C) 31/54 Notice the amber NAV, F/CTL and AUTO FLT system titles. This means that these systems are affected by the failure. Their related procedures are stacked after the current one and will appear with the completion of the EMER CONFIG procedure. ELECTRICAL MENU Abnormal operation (C) 32/54 Notice also the visible secondary failures concerning the CAB PRESS, HYD and FUEL systems. There may be other secondary failures that are not yet displayed since there is an overflow indication(green arrow). We will now jump to the end of the EMER ELEC procedure and see how you can view the secondary failures. ELECTRICAL MENU Abnormal operation (C) 33/54 The system titles have disappeared when their procedures are completed. The complete list of the secondary failures is now visible. As the lower ECAM is not available, you will have to manually call the ECAM pages associated with the secondary failures on the E/WD. You have to press and hold the related key on the ECP in the same way that you previously called the ECAM ELEC page. ELECTRICAL MENU Abnormal operation (C) 34/54 We will now assume that all the ECAM pages of the secondary failures have been reviewed. As you cleared the last one, memo messages appeared on the E/WD. The green RAT OUT memo message confirms that the RAT is no longer stowed. The green EMER GEN memo message indicates that the emergency generator is running and supplying the system. You will have the opportunity to practice the EMER ELEC CONFIG procedure during your simulator sessions. We will now study the case of a RAT stall. ELECTRICAL MENU Abnormal operation (C) 35/54 If the RAT stalls, for example at low speed during the approach, the emergency generator is no longer powered and the supply is automatically transferred to the batteries. ELECTRICAL MENU Abnormal operation (C) 36/54 The ECAM ELEC page has been called for you. Observe that the EMER GEN indications have disappeared. ELECTRICAL MENU Abnormal operation (C) 37/54 As the battery discharge current is high, the current indications are displayed in amber. ELECTRICAL MENU Abnormal operation (C) 38/54 The batteries feed the DC ESS bus and, via the static inverter, supply the AC ESS bus. ELECTRICAL MENU Abnormal operation (C) 39/54 Both SHED ESS buses are automatically shed which is indicated by amber SHED indications below their respective buses. Notice that, during this phase, the APU start is inhibited. ELECTRICAL MENU Abnormal operation (C) 40/54 On the ground, the DC BAT bus is automatically connected to the batteries. At low speed, the AC ESS bus is shed leading to the loss of all screens. ELECTRICAL MENU Abnormal operation (C) 41/54 We will now review some indications we did not have the opportunity to see when performing the previous procedures. ELECTRICAL MENU Abnormal operation (C) 42/54 As a result of the electrical failure, the RAT is normally automatically deployed. During the RAT extension, the electrical system is powered from the batteries. The approximate flight time on batteries is 30 min. Let’s see what happens if the RAT fails to deploy automatically. ELECTRICAL MENU Abnormal operation (C) 43/54 If the RAT fails to extend, a specific line appears in the EMER ELEC procedure telling you to manually extend the RAT on the EMER ELEC PWR panel.

ELECTRICAL MENU Abnormal operation (C) 49/54 After a RAT extension, if the emergency generator is not working, the red FAULT light stays illuminated on the RAT & EMER GEN indicator. This failure causes the aircraft to be powered only from the batteries. ELECTRICAL MENU Abnormal operation (C) 50/54 In case of smoke detection in the avionics bay, the amber SMOKE light illuminates on the GEN 1 LINE pb sw. A Master caution and an ECAM procedure are also triggered. ELECTRICAL MENU Abnormal operation (C) 51/54 When the GEN 1 LINE pb sw is pressed generator 1 is disconnected from the system.

ELECTRICAL MENU Abnormal operation (C) 54/54 The avionics smoke ECAM procedure leads to the shedding of the main bus bars. In this case, the electrical system configuration is the same as in emergency except for the fuel pumps which remain supplied.
