Which altitude is maintained while performing The Turn Pattern (TP)?

The correct choice emphasizes the importance of maintaining altitude during The Turn Pattern (TP). When executing the Turn Pattern, pilots are trained to keep their altitude steady to ensure consistent performance and control. This allows for a stable reference point to accurately evaluate the aircraft's performance during turns, maintaining the required airspeed, and ensuring proper coordination and balance throughout the maneuver.

By maintaining altitude, pilots can focus on managing the aircraft's bank and turn rate, as well as ensuring that they do not inadvertently enter a climb or descent that could affect the execution of the turn. This practice is crucial, particularly in primary flight training, as it helps students develop a strong foundation in aircraft handling and situational awareness.

The other options suggest changes in altitude, which could complicate the training exercise and distract from mastering the technique of the turn itself. Thus, maintaining altitude is a critical aspect of the Turn Pattern, helping trainees develop consistent and safe flying habits.
