The wing anti-ice cross bleed selector will allow one engine to be selected even with the bleed valves control selector in AUTO.

• A. True
• B. False
• C. Only in HIGH mode
• D. Only with manual bleed valves

Answer: (A)

The cross-bleed path is about giving you a manual override to feed wing anti-ice from a single engine’s bleed air, regardless of what the automatic bleed control is doing. When the bleed valves control selector is in AUTO, the system normally manages sources automatically, but the cross-bleed selector provides a way to force the wing anti-ice feed from the chosen engine. This is useful for single-engine operations or when one engine’s bleed is unavailable, ensuring anti-ice can be maintained without needing both engines’ bleeds active. It isn’t limited to HIGH mode or to manual bleed valves—it's about enabling a single-engine bleed source through the cross-bleed path. So the statement is true.
