WebAug 13, 2024 · On standard aircraft, the point of the tail is to make the aircraft as stable as possible. This means it’s usually a solid vertical stabilizer for training aircraft and passenger jets. For airplane aerodynamics in an air show, the goal for the tail is somewhat different. Specific tail design enables aerobatic pilots to fly with precision. WebStable Aircraft. If a statically stable aircraft is in steady level flight and encounters a vertical gust, or the pilot quickly moves the elevator away from the trim position and back again, …
