Overview The purpose of this avionics smoke presentation is two-fold: •The ECAM Avionics Smoke procedure is not intuitive •The ECAM action steps alter many aircraft systems. This lecture provides a general explanation of the abnormal procedure. It is intended to minimize possible confusion should

ECAM PROCEDURE Considerations before executing the A the AVIONICS VIONICS SMOKE ECAM procedure include: • The Operator’s Abnormal/Emergency procedures. • If the source and severity of the smoke dictate continuation of the ECAM procedure, the flight crew manually places the aircraft in the emergency electrical configuration. • The ECAM procedure contains two conditional (IF) statements to preclude

ECAM Execution

The AVIONICS The A VIONICS SMOKE ECAM procedure begins with the conditional statement – statement – IF PERCEPTIBLE SMOKE:

















ECAM Execution If smoke is not perceived (sight or smell) avionics smoke may not actually exist. If that is the case, D O NOT proceed with the ECAM .

If any crew member perceives smoke, proceed with the E C A M .

ECAM Execution

EMER ELEC PWR ...MAN ON action step has now moved up and is the next step to be completed.

Once this step is completed you will see the ELEC page change again.















ECAM Execution By performing the EMER ELEC PWR ...MAN ON action step, the wind driven Ram Air Turbine (RAT) extends and provides BLUE hydraulic pressure which powers the Emergency Generator (EMER GEN).

We will see how this changes the ELEC page.

Is there a difference















ECAM Execution The E/WD indicates the RAT has been deployed (RAT OUT) and the emergency generator is functional (EMER GEN). The ELEC page depicts the EMER GEN is powering the AC ESS bus and DC ESS bus through the ESS TR. The “Rats Nest” is a term referring to the EMER GEN, ESS TR, DC ESS and AC ESS indications on the ELEC page.

Another condition statement has moved up. WHEN EMER GEN AVAIL: is mandating that the flight crew determine the availability of the EMER GEN.

The RAT OUT, EMER GEN, and “Rats Nest” provide positive indications that the emergency generator is















ECAM Execution

After the EMER GEN is available, the ECAM procedure directs the pilot to select GEN 2 off. This is the BIG action step! Before performing this action step, there are a few things to consider. Emergency electrical power Autopilot

Notice that once GEN 2 goes offline the only display units left are the captain’s PFD, ND and the E/WD.

Now that we have seen all the information available on the status page; it is time to let go of the STS button and go back to a lights out ECAM. Once the ECAM is complete, time permitting, the QRH Electrical Emergency Configuration summary should be consulted.















Do you realize smoke in the cockpit or cabin may occur without generating an ECAM message. Where is the crew expected to go for an abnormal without an ECAM message?
