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.

The ECAM ELEC page has been called for you.
Observe that the EMER GEN indications have
disappeared.

The batteries feed the DC ESS bus and, via the
static inverter, supply the AC ESS bus.

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.

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.

We will now review some indications we did not
have the opportunity to see when performing the
previous procedures.

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.

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

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.
