True or False: In the event the IBF becomes clogged in flight, the bypass door will open automatically.

• A. True
• B. False

Answer: (B)

The statement is false. In the event that the Inlet Barrier Filter (IBF) becomes clogged, the bypass door does not open automatically. Instead, the aircraft system relies on pilot input or specific operational procedures to manage environmental conditions and filter performance. The bypass door is designed to provide an alternative airflow route to the engine if the IBF is obstructed, but it requires a manual activation to ensure safe operation. This operational characteristic ensures that the pilot maintains control over such critical systems, preventing unintended consequences from automatic actions that could compromise aircraft safety.
