The tail unit consists of the vertical stabilizer (fin) and horizontal stabilizer. The fin has a rudder to control the left and right movement of the aircraft. The horizontal stabilizer has an elevator to control up and down movement. Together, the fin and rudder and horizontal stabilizer and elevator provide stability and control of the aircraft during flight. The tail unit is constructed similarly to wings, with spars and ribs covered by a metal skin, and provides important stability and steering functions.

3. The airplane consists
of five structural units:
• the power plant,
• the fuselage,
• the wings,
• the tail unit,
• and landing gear.
Main parts of the aircraft

4. The tail unit
• The tail unit is the main part of the aircraft.

5. The tail unit (empennage)
provides stability and
control of the aircraft. Its
function is to provide
stability and control of the
aircraft.

6. Vertical
Horizontal
They are of
symmetrical airfoil
section
2 surfaces

8. The REAR part
is in the form
of a flap
which is
operation
providing
directional
control
The
FRONT
part is
fixed.
Each is
divided
into two
parts

9. • The vertical surface is
called the “FIN”.
• Vertical stabilizer has
rudder, which turns the
aircraft right and left.

10. The horizontal
surface is known as
the “STABILISER”.
Horizontal stabilizer
has elevator, which
turns the plane up
and down.

11. They have two main members:
spars and ribs to which metal skin
is attached.
Both stabilisers are
very similar to
wing in
construction.
They are usually of
all-metal
construction of the
cantilever type.

13. • The vertical stabilizers or fin
provides directional
stability of the aeroplane in
flight.
• It also serves as the
base to which the
rudder is attached.
