What happens beyond a 37° bank in the pitch rate command roll submode?

What happens beyond a 37° bank in the pitch rate command roll submode?

• A. Increased nose up trim for attitude hold
• B. A flashing 'ALS' indicator appears on the PFD
• C. Disables attitude hold function requiring pilot activation
• D. Utilizes three hydraulic systems for each elevator

Answer: (C)

When the bank angle exceeds 37 degrees in pitch rate command roll submode, the attitude hold function becomes disabled. This means that the aircraft will no longer maintain its attitude automatically, and the pilot will need to manually control the aircraft's attitude to maintain level flight or to execute maneuvers. This safety feature ensures that the aircraft does not inadvertently enter a bank angle that could lead to a loss of control without the pilot's active management. The requirement for manual activation emphasizes the importance of pilot awareness and engagement in flight operations, especially during steep bank angles. Additionally, while other options address different aircraft functions or indicators, they do not pertain specifically to the consequences of exceeding the 37-degree bank limit in this context.
