Q14384 [RAM AIR] What is the outflow value position at or greater than 1 PSI of differential pressure?

Opens fully.

Remains Normal

Closes.

Opens to 50%

Correct!

Incorrect!

Q14370 What should you NOT do if GD LP Air is connected to the pneumatics system?

Use APU Bleed Air at the same time. This prevents adverse effects on the Air Conditioning System.

Use packs at the same time. This prevents adverse effects on the Air Conditioning system

Close off the XBLEED value.

Open the XBLEED value.

Correct!

Incorrect!

Q14369 Is WAI (Wing Anti Ice) allowed if only one bleed system is in operation?

Yes.

Yes but PACK FLOW selector must be set to LO, due to precooler performance.

No, precooler performance is degraded.

Yes but to ensure precooler performance one pack must be switched off when using anti-ice.

Correct!

Incorrect!
