If one module of the AMSAC fails, what would be the result?

When one module of the AMSAC (Automatic Management of the Supply of Air for Conditioning) fails, the system typically experiences a partial loss of control over the bleed air systems. This is because AMSAC is designed to manage the various functions of bleed air systems, and when one module fails, it may disrupt the full functionality of the system, but it does not lead to a complete failure. The remaining operational modules can still maintain some level of control and system capability, ensuring that some, if not all, bleed air functionalities can continue to operate effectively. The other choices suggest a complete loss or no impact, which would not accurately describe the behavior of the AMSAC in the event of a single module failure. Therefore, the answer correctly reflects the operational dynamics of the AMSAC system.
