Sample Pneumatic, Ice and Rain Protection questions with answers
Three questions from the free preview. Think of your answer first, then open the explanation.
1.From which engine compressor stages is A320 bleed air taken?
- A.The HP stage only, via the precooler
- B.An intermediate stage and the HP stage
- C.The fan stage and an LP stage
Show answer and explanation
Correct answer: B. An intermediate stage and the HP stage
Air comes from an IP stage, with the HP valve adding HP stage air when IP pressure is too low at low power.
2.When does the A320 HP bleed valve supply air to the system?
- A.At low engine power
- B.At takeoff power
- C.Only for wing anti-ice
Show answer and explanation
Correct answer: A. At low engine power
At low power the IP stage pressure is not enough, so the HP valve opens. At takeoff it is closed and IP air is used.
3.What prevents reverse flow into the A320 IP bleed stage when the HP valve is open?
- A.The fan air valve
- B.The IP check valve
- C.The overpressure valve
Show answer and explanation
Correct answer: B. The IP check valve
The IP check valve protects the IP compressor stage from HP air flowing back into it.
