An autopilot is a mechanical, electrical, or hydraulic system used to guide a vehicle without assistance from a human being. Most people understand an autopilot to refer specifically to aircraft, but self-steering gear for ships and boats is sometimes also called by this term.
In the early days of transport aircraft, aircraft required the continuous attention of a pilot in order to fly in a safe manner. This created very high demands on crew attention and high fatigue. The autopilot is designed to perform some of the tasks of the pilot.
The first aircraft autopilot was developed by Sperry Corporation in 1912. Lawrence Sperry (Son of famous inventor Elmer Sperry) demonstrated it two years later in 1914, and proved his credibility of the invention, by flying the plane with his hands up.
The autopilot connected a gyroscopic attitude indicator and magnetic compass to hydraulically operated rudder, elevator, and ailerons. It permitted the aircraft to fly straight and level on a compass course without a pilot's attention, thus covering more than 80% of the pilot's total workload on a typical flight. This straight-and-level autopilot is still the most common, least expensive and most trusted type of autopilot. It also has the lowest pilot error, because it has the simplest controls.
In the early 1920s, the Standard Oil tanker J.A Moffet became the first ship to use autopilot.
Modern autopilots generally divide a flight into taxi, take-off, ascent, level, descent, approach, landing, and taxi phases. Autopilots exist that automate all of these flight phases except the taxiing. Landing on runway and controlling the aircraft on rollout i.e keeping it on the centre of the runway is CAT 3b landing, used on the majority of major runways today. Landing, rollout and taxi control to stand is CAT 3c. This is not usually used to date but may be used in the future. Some incorporate automated collision-avoidance; the most popular collision avoidance for aircraft is called TCAS (Traffic alert and Collision Avoidance System). An autopilot is often an integral component of a Flight Management System.
Modern autopilots use computer software to control the aircraft. The software reads the aircraft's current position, and controls a flight control system to guide the aircraft. In such a system, besides classic flight controls, many autopilots incorporate thrust control capabilities that can control throttles to optimize the air-speed, and move fuel to different tanks to balance the aircraft in an optimal attitude in the air.
Although autopilots handle new or dangerous situations inflexibly, they generally fly an aircraft with a lower fuel-consumption than all but a few of the best pilots.

Oh yes. Plus its not like there is no pilot. If the plane seems to be turning, climbing, descending. speeding up or slowing down the pilot can always take back manual control. Do you trust the cruise control in your car? It's so much easier than trying to maintain a constant speed for hours. Same basic concept.

Hypocrite, egocentric, grasping..... elect I say better? This female has some nerve. i will't stand her, even better than Obama at cases. Obama is clueless yet i will see some if his habit is triggered through his experience of decency (though that's critically misdirected). This female appears triggered through skill, greed and he or she lies. The Newsweek article that develop into on the records very last evening from submit-9/11 develop into unearthed that stated that she and different individuals of the senate and congress knew about water-boarding and were informed. yet, the day till now as we talk she develop into on television (till now the article got here to gentle) declaring she easily knew no longer some thing of it. C'mon female, get a grip. And, if her memory is that undesirable and that selective, she particular would not belong in her place of work. a real waste-product who desires to bypass back to her multimillion greenback Hollywood abode and performance cocktail activities. i might want to be satisfied for us to pay that that one flight back.

Yeah, they use them all the time. Pilots are merely for decoration, Computers fly the planes.
