EMER ELECT PWR Panel (Rev. 3)

Question 1

What is the significance of the red FAULT illuminating on the RAT & EMER GEN light?

Answer 1

AC BUS 1 and AC BUS 2 are lost and the emergency generator is not supplying electrical power

Question 2

When would the red FAULT light on the RAT & EMER GEN light normally illuminate?

Answer 2

The fault light will illuminate once the RAT is deployed and electrical power is not being supplied (approx. 8 seconds)

Question 3

How can the RAT be deployed?

Answer 3

• Manually by pushing MAN ON (EMER ELEC PWR panel) or RAT MAN ON (HYD panel)
• Automatically by the loss of both AC BUS 1 and AC BUS 2

Question 4

What is the difference between the automatic RAT deployment and manual RAT deployment by pressing the RAT MAN ON on the HYD panel?

Answer 4

RAT MAN ON supplies BLUE HYD pressure only, no electrical generation

Question 5

After deploying the RAT by pressing the RAT MAN ON pb on the HYD panel it becomes necessary to also extract electrical power. How can this be accomplished?

Answer 5

By pressing the MAN ON pb on the EMER ELEC PWR panel

Question 6

What does the RAT supply?

Answer 6

Blue HYD system pressure and the emergency electrical generator

Question 7

What would cause the GEN 1 LINE SMOKE light to illuminate?

Answer 7

Smoke detectors (particle detectors) in the avionics ventilation ducting

Question 8

Aside from the GEN 1 LINE SMOKE light, what would be other indications of avionics smoke?

Answer 8

• ECAM warning

- Amber FAULT lights in the EXTRACT and BLOWER pbs on the VENTILATION panel

Question 9

If the ECAM directs a pilot to select GEN 1 LINE pb sw to OFF, what will be accomplished?

Answer 9

• Gen 1 line contactor opens (white OFF light illuminates)
• AC BUS 1 powered by GEN 2 through the bus tie contactors
• GEN 1 powers one fuel pump directly in each wing tank
