Is the statement "The rudder trim is usually applied first because a correction for yaw precipitates a change in the trim setting for pitch and roll" true or false?

The statement is true because when flying, particularly in a multi-axis environment, yaw can significantly influence an aircraft's overall stability. Applying rudder trim first is a common practice, especially if the aircraft is experiencing a yawing tendency due to asymmetrical thrust or some other factor. By correcting for yaw, you help to maintain coordinated flight, which is crucial for both efficiency and safety.

When yaw is corrected, it tends to stabilize the aircraft's behavior in roll and pitch, as uncoordinated flight often leads to unwanted changes in these axes. If the yaw is not addressed initially, it can lead to additional pitch and roll adjustments that complicate the flight. Hence, starting with rudder trim simplifies the task of maintaining control and allows for more stable adjustments.

The other options suggest varying perspectives on the statement's truthfulness but do not align with the established practice of prioritizing yaw corrections to maintain stable flight and minimize further issues with pitch and roll.
