What flight configuration is suggested for achieving heading 135 degrees with no climb or dive involved?

The correct choice, which indicates "no climb, no dive; heading 135 degrees," is appropriate because it directly addresses the criteria of maintaining a specific heading without altering altitude. In aviation, achieving a particular heading while keeping level flight is crucial for navigation.

This choice reflects a stable flight attitude where the aircraft can turn to the desired heading (135 degrees) without any change in vertical position, which is essential when navigating through airspace where altitude stability is necessary. Keeping the nose level ensures that the aircraft does not gain or lose altitude, which is important for safety and maintaining control, particularly in environments where other aircraft may be present.

The other options suggest maneuvers that involve changing pitch or bank angles, which distract from the goal of maintaining level flight while turning to the specified heading. Such maneuvers would lead to either a climb or a descent, which is not aligned with the requirement stated in the question.
