What does the throttle hold help to manage during specific flight phases?

• A. Altitude stabilization
• B. Engine RPM
• C. Fuel flow
• D. Weight distribution

Answer: (B)

The throttle hold function is specifically designed to maintain engine RPM during certain flight phases, which is critical for ensuring optimal engine performance and efficiency. By holding the throttle at a predetermined setting, the system allows pilots to manage engine speed without constant manual input, especially during tasks that may require hands to be free for other controls. This is particularly useful during phases of flight such as approach and landing, where stable engine RPM is essential for consistent performance and safety.

Maintaining appropriate engine RPM through throttle hold ensures that the aircraft operates smoothly, reducing the likelihood of unintentional power changes that could affect performance and safety. It also aids in managing the overall power requirements of the aircraft while minimizing pilot workload, allowing for improved focus on flying tasks.
