CHAPTER 47 Flashcards
1
Q
What controls the Nitrogen Enriched Air (NEA) flow to the centre fuel tank?
A
The Dual Flow Shut Off Valve (DFSOV) controls the NEA flow to the centre fuel tank and lets the system change between low/mid/high NEA flow in relation to the flight phases.
2
Q
Where are the temperature and pressures monitored from?
A
Downstream of the Double ultra low particle (D-ULPA) filter, one temperature sensor and one pressure sensor send air parameters to the IGGS Controller Unit (ICU).
3
Q
Where is the oxygen concentration measurement taken from?
A
Downstream of the ASM, an oxygen sensor measures the oxygen rate to prevent a high oxygen concentration in the centre fuel tank.
