Definition
The tail section of an airplane, consisting of the horizontal stabilizer, vertical stabilizer, elevator, and rudder. It provides stability and directional control in flight.
Plain English
The whole tail assembly of the airplane — the fin sticking up, the small wing-like surfaces sticking out the back, and the moving control surfaces attached to them.
Context Anchor
You will see this term in aircraft structure descriptions, preflight inspection discussions, and explanations of the tail flight controls.
Derivation
The word comes from the French word penne, which means “feather” (from the Latin penna), and in French empenner, as a verb, means “to feather an arrow” — putting feathers on the back of an arrow so it flies straight and stable.
Why Pilots Care
The empennage supplies directional and pitch stability; damage or failure reduces control authority and can lead to loss of control.
Intuition Check
Do not think of the empennage as just the decorative back end of the airplane. It is a working control and stability section of the aircraft.
Example Sentence 1
During preflight, the pilot walked to the empennage and checked the elevator and rudder for free movement.
Example Sentence 2
Ice accumulation on the empennage can reduce elevator effectiveness and create pitch control problems.
