Pressurization Loss is associated with which action?

Pressurization Loss is associated with which action?

• A. Engine Fire on Ground
• B. Loss of Cabin Pressure in Flight
• C. Electrical Failure
• D. Emergency Engine Shutdown

Answer: (D)

Pressurization loss is tied to the aircraft’s bleed-air system, which is normally supplied by the engines (and sometimes the APU). When cabin pressurization can no longer be maintained, it points to a fault in the bleed-air pathway or its control. The quickest, most direct way to isolate the source of the bleed air and stop any leak or fault from propagating is to shut down the engine supplying the problematic bleed air. This makes emergency engine shutdown the action most aligned with resolving a pressurization fault. The other options describe events or systems not directly implementing a corrective step for a pressurization loss: an engine fire on the ground is a different scenario, loss of cabin pressure in flight describes the condition itself rather than a corrective action, and an electrical failure involves a separate system.
