tailplane

The pilot checks the tailplane before takeoff.

Definition

Noun: 1. A fixed horizontal airfoil forming part of the tail assembly of an aircraft: The tailplane is a wing-like surface, typically located at the rear of the fuselage. Its primary function is to provide longitudinal (pitch) stability, helping to keep the aircraft's nose at a steady angle relative to the airflow. The movable control surface called the elevator is attached to its trailing edge.

Usage

The term "tailplane" is used specifically in aviation to describe a key structural and aerodynamic component of an aircraft's empennage (tail section). It is a technical term common in engineering, piloting, and maintenance contexts. * The design of the tailplane is crucial for the aircraft's stability in flight. * During the inspection, the engineer checked the tailplane for any signs of damage. * In most aircraft configurations, the tailplane is positioned at the rear of the fuselage.

Advanced Usage
  • "All-moving tailplane" or "Stabilator": A type of tailplane where the entire horizontal surface moves as one unit to control pitch, instead of having a separate fixed surface and a movable elevator. This design is common on high-performance and military jets.
    • The fighter jet uses an all-moving tailplane for more responsive pitch control.
Variants and Related Words
  • Horizontal Stabilizer: This is the most common synonym for "tailplane" in American English and general aviation terminology. The two terms are often used interchangeably.
  • Empennage: A broader term referring to the entire tail assembly of an aircraft, which includes the tailplane/horizontal stabilizer, the fin/vertical stabilizer, and the associated control surfaces (elevator, rudder).
  • Elevator: The hinged control surface attached to the trailing edge of the tailplane. The pilot moves the elevator to make the aircraft pitch up or down.
Synonyms
  • Horizontal stabilizer
  • Horizontal tail surface
Antonyms
  • Fin / Vertical Stabilizer: The vertical airfoil at the rear of an aircraft that provides directional (yaw) stability. It is the vertical counterpart to the horizontal tailplane.

Noun
  1. the horizontal airfoil of an aircraft's tail assembly that is fixed and to which the elevator is hinged
