Avionics Ventilation Flashcards
Draw the Avionics Ventilation system & adjust the valves for:
Open Circuit
Closed Circuit
Intermediate Circuit
Blower or Extract fault
Smoke configuration
When is the Avionics ventilation system in:
Open Circuit
Closed Circuit
Intermediate Circuit
Abnormal
Smoke configuration
Open: On ground when above on-ground temp threshold
Closed: On ground when beneath on-ground threshold and In flight when beneath In-flight threshold
Intermediate: In flight when above in-flight threshold
Abnormal: when blower OR extract p/b
Smoke: when blower AND extract p/b
What are the avionics ventilation ground and flight temperature thresholds?
On ground: +12 temperature increasing, +9 temperature decreasing
In flight: +35 temperature increasing, +32 temperature decreasing
What’s happens when:
blower is set to ovrd?
extract is set to ovrd?
blower + extract set to ovrd?
