Which mode of operation provides short-term attitude stabilization to reduce pilot workload?

• A. SAS
• B. ATT HOLD
• C. HDG HOLD
• D. VS

Answer: (A)

The mode of operation that provides short-term attitude stabilization to reduce pilot workload is the Stability Augmentation System (SAS). SAS is designed to enhance the stability of the aircraft by automatically making adjustments to the control surfaces. This system helps maintain the desired attitude of the aircraft without requiring constant input from the pilot, allowing for a smoother flying experience and decreasing fatigue.

By using SAS, pilots can focus more on other operational tasks rather than continuously managing the aircraft's stability. This is particularly beneficial during periods of turbulence or when transitioning between different flight phases. The implementation of SAS ultimately contributes to safer and more efficient flight operations.

Other modes of operation, such as ATT HOLD, HDG HOLD, and VS, have different purposes that focus on specific parameters, like holding a pitch attitude, maintaining a heading, or managing vertical speed, respectively. While they may assist with certain aspects of flight control, SAS specifically targets short-term attitude stabilization to relieve pilot workload.
