AIRBUS 220- Pneumatic System Exam With complete
solution– Expert Verified | Latest Version | 100 Guaranteed
Success
What is trim air? - supplies additional hot bleed air through 4 trim air valves which
is mixed with cold air from PACKs to optimize temperatures in their respective
zones
components of trim air system - - 4 trim air valves
- TAPRV (trim air pressure relief valve) = regulates volume of hot bleed air to the
trim air valves
- TASOV (trim air shutoff valve) = opens when additional heating is required on
the ground, back up to TAPRV
what are the names of the two valves related to trim air system - TASOV = trim air
shutoff valve
TAPRV = trim air pressure relief valve
What lines of trim air does IASC 1 control - 1&4 (flight deck, and aft cab)
What lines of trim air does IASC 2 control? - 2&3 (fwd cargo and fwd cabin)
What happens if you turn off the recirc air fan? - - if in vent, cargo ventilation
valves will close
- in low or high, cargo ventilation valves will not close unless there is a fire
Functions of the IASC - - pressurization
