Under which condition would BLEED MISCONFIG appear on EICAS?

• A. Bleed valves are in manual mode.
• B. Bleed valves are in automatic mode.
• C. Wing ice protection is active.
• D. APU bleed is used for cabin pressurization.

Answer: (A)

BLEED MISCONFIG on EICAS happens when the bleed air system isn’t configured as the automatic bleed logic expects. This typically occurs if bleed valves are placed in manual mode. When the system is manual, the valves can be set independently of the auto coordination that matches engine bleeds, APU bleed, and other bleed demands. If those manually chosen positions don’t align with what the automatic system requires for current operations, a misconfiguration alert is produced. In automatic mode, the bleed system maintains a consistent configuration, so this warning wouldn’t appear. The other options don’t inherently cause a bleed misconfiguration—their states don’t by themselves create the mismatch the system flags.
