3. • Aircraft required the continuous
attention of a pilot.
• The constant attention led to serious
fatigue for pilot.
• So that autopilot is designed to perform
some of the tasks of the pilot.
• An Autopilot is a system used to guide a vehicle without assistance
from a person. The function of the autopilot is stabilization.
4. There are mainly 3 types of autopilot
• A single-axis autopilot usually
manages both the ailerons.
ROLL MODE
• A two-axis autopilot manages
elevators and ailerons.
ROLL and PITCH MODE
• A three-axis autopilot manages
all three basic control systems
ailerons, elevators and rudder.

5. • The heart of a modern
automatic flight control
system is a computer.
• Computer gather all the
details required to
control the plane.
• From sensors located on
the airplane surfaces.
• They collect data from
other airplane systems
and equipment also.
6. • The autopilot system is
controled by the auto-pilot
hydraulic unit.
• The auto-pilot hydraulic unit is
intented to transform the auto-
pilot computer electrical
comands in to hydraulic and
mechanical commands. These
comands operate the flight
control linkage and bring the
aircraft attitude or heading back
to the reference coordinates.
