Definition
An empennage design in which the horizontal stabilizer is mounted at the top of the vertical stabilizer rather than at the base of the fuselage. In stall behavior, T-tail configurations are notable because the horizontal stabilizer sits above the wing's wake, which can leave the elevator effective deep into a stall and, in some designs, allow the wing's disturbed airflow to blanket the tail at high angles of attack, producing a deep stall from which recovery may be difficult.
Plain English
Airplanes where the horizontal tail is mounted on top of the vertical tail, forming the shape of the letter T when viewed from the front or side.
Context Anchor
Seen in stall training and airplane handling discussions, especially when learning why some airplanes require careful stall recognition and prompt recovery.
Derivation
The term comes from the visual shape of the tail. The vertical tail is the upright part, and the horizontal tail sits across the top, so the whole arrangement looks like a capital letter T.
Why Pilots Care
T-tails can experience a deep stall when wing wake blankets the tail, requiring specific recovery techniques.
Grounding Statement
Picture the airplane at a very nose-high angle: the wings can disturb the air flowing back toward the high-mounted tail, which may make the pitch control less effective.
Intuition Check
T-tail does not mean the airplane has a special kind of stall. It means the tail surfaces are arranged in a T shape, which can affect pitch control during some stalls.
Example Sentence 1
The instructor briefed the student on the unique stall characteristics of T-tail configurations before their first flight in the Tomahawk.
Example Sentence 2
Pilots checked for T-tail configurations when reviewing handling notes for the new jet.
