What should a pilot do to avoid consistent gain in altitude when rolling out from a turn?

To avoid a consistent gain in altitude when rolling out from a turn, a pilot should relax back pressure during the roll-out. When an aircraft is in a turn, it generates a load factor that requires back pressure to maintain level flight. However, as the aircraft transitions back to straight and level flight, if the pilot continues to apply back pressure, it can result in an excessive pitch attitude. Consequently, this causes the aircraft to climb as the vertical component of lift increases.

By relaxing the back pressure during the roll-out, the pilot allows the aircraft to settle into a level flight attitude, thus preventing an unwanted altitude gain. This action helps to maintain a proper pitch attitude and ensures a smooth transition back to straight flight without inadvertently increasing altitude. Properly managing control inputs throughout the maneuver is essential for effective altitude management and overall flight safety.

The other options suggest maintaining or increasing back pressure, which would exacerbate the climb situation, and applying forward pressure immediately upon roll-out, which might not adequately address the need for a smooth adjustment in pitch and can lead to abrupt changes in flight attitude.
