5. EMER ELEC PWR Panel (Electrical) Flashcards
What is the significance of the red FAULT illuminating on the RAT & EMER GEN light?
AC BUS 1 and AC BUS 2 are lost, and the emergency generator is not supplying electrical power
When would the red FAULT light on the RAT & EMER GEN light normally illuminate?
The fault light will illuminate once the RAT is deployed and electrical power is not being supplied (approximately eight seconds)
How can the RAT be deployed?
• Manually by pushing MAN ON (EMER ELEC PWR Panel) or RAT MAN ON (HYDRAULIC Panel).
• Automatically by the loss of both AC BUS 1 and AC BUS 2
What is the difference between the automatic RAT deployment and manual RAT deployment by pressing the RAT MAN ON on the HYD panel?
RAT MAN ON supplies Blue Hydraulic pressure only, no electrical generation
After deploying the RAT by pressing the RAT MAN ON pushbutton on the HYD panel it becomes necessary to also extract electrical power. How can this be accomplished?
By pressing the MAN ON pushbutton on the EMER ELEC PWR
What does the RAT supply?
Blue Hydraulic System pressure and the emergency electrical generator
What would cause the GEN 1 LINE SMOKE light to illuminate?
Smoke detectors (particle detectors) in the avionics ventilation ducting
Aside from the GEN 1 LINE SMOKE light, what would be other indications of avionics smoke?
- ECAM warning
- Amber FAULT lights in the EXTRACT and BLOWER pushbuttons on the VENTILATION panel
If the ECAM directs a pilot to select GEN 1 LINE pb sw to OFF, what will be accomplished?
- 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
