The document discusses the history and development of autopilot systems. It notes that the first autopilot was developed by Elmer Sperry in 1912 to help reduce pilot fatigue from long flights. There are three main types of autopilot systems - single-axis, two-axis, and three-axis - which control different aircraft functions. Modern autopilots are computer-based and use sensors to gather flight data and make calculations to guide the aircraft similarly to a human pilot. While autopilots assist pilots and improve safety, pilots must still closely monitor the aircraft as autopilots can fail or be overridden.

2.  An Autopilot is a system used to guide a vehicle
without assistance from a person.
 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.

3.  The first aircraft
autopilot was developed
Elmer Ambrose
Sperry, Sr. in 1992.
 Demonstrated by his
son Lawrence
Sperry in 1914.

4. There are mainly 3 types of autopilot
 A single-axis autopilot usually manages both the
ailerons.
 A two-axis autopilot manages elevators and ailerons.
 A three-axis autopilot manages all three basic control
systems ailerons, elevators and rudder.

6.  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.

7.  They collect data from other airplane systems and
equipment also.
 Which
includes gyroscopes, accelerometers, altimeters, compa
sses and airspeed indicator, altitude indicator.

9.  The processors complex calculations accurately
, compare it to pilot.
 It perform the same duties as a highly trained pilot.
 Autopilots don't just make flights smoother , they make
them safer.
 It reduce the fatigue to pilot due to constant attention..

10.  Autopilots can and do fail.
 It can’t be override.
 Airplane should be crashes if pilots have failed to
disengage the automatic flight control system.

11.  A position sensor can also fail, resulting in incorrect
input data to the autopilot computer.
 Even if on autopilot mode, pilot need to be active.

12.  Most commercial jets have had autopilot.
 Even smaller planes are incorporating autopilot
systems.
 Garmin, Thales ,Rockwell Collins and Honeywell are
some manufacturers of autopilot.

13.  The Garmin bringing true automatic flight control to a
new generation.
 Autopilots are also used in boats (known as self-
steering gear), space craft, missiles.
