The vertical stabilizer is the fixed vertical surface of the empennage. A vertical stabilizer or tail fin [1] [2] is the static part of the vertical tail of an aircraft. [1] The term is commonly applied to the assembly of both this fixed surface and one or more movable rudders hinged to it. Their role is to provide control, stability and trim ...
A twin-tailed B-25 Mitchell in flight. A twin tail is a type of vertical stabilizer arrangement found on the empennage of some aircraft.Two vertical stabilizers—often smaller on their own than a single conventional tail would be—are mounted at the outside of the aircraft's horizontal stabilizer.
A Boeing 737 uses an adjustable stabilizer, moved by a jackscrew, to provide the required pitch trim forces. Generic stabilizer illustrated. A horizontal stabilizer is used to maintain the aircraft in longitudinal balance, or trim: [3] it exerts a vertical force at a distance so the summation of pitch moments about the center of gravity is zero.

USAAF unit identification aircraft markings, commonly called "tail markings" after their most frequent location, were numbers, letters, geometric symbols, and colors painted onto the tails (vertical stabilizer fins, rudders and horizontal surfaces), wings, or fuselages of the aircraft of the United States Army Air Forces (USAAF) during the ...

The expression "vertical stabilizer" appears not to be used. Dolphin (t) 13:53, 23 September 2021 (UTC) Oppose: This article is about the fixed part, so it is correctly named. "The empennage includes the entire tail group and consists of fixed surfaces, such as the vertical stabilizer and the horizontal stabilizer. The movable surfaces include ...
The MD-11 has a center engine at the base of the vertical stabilizer, like the DC-10. Additionally, the nacelle has a bulge at the front, similar to the DC-10-40 variant. The lack of innovation from McDonnell Douglas during the MD-11's design had been attributed to the company's declining cash flow, as it struggled with problems with its ...
