Pronunciation: [ˌɔːtə͡ʊpˈa͡ɪləts] (IPA) 
The word "autopilot" is spelled with an "s" at the end when referring to multiple automated systems. The IPA transcription for "autopilots" is /ˈɔː.təʊ.paɪ.ləts/, with stress on the second syllable. The "o" in "auto" is pronounced with a long "o" sound, while the "i" in "pilot" is pronounced with a short "i" sound. The final "s" sound is represented by the IPA symbol /s/, which is unvoiced and sounds like a hissing sound.
Autopilots are automated systems or devices designed to control the movement and operation of a vehicle, typically an aircraft, without direct human intervention. These systems employ various technological components, such as computers, sensors, and actuators, to monitor and adjust the vehicle's course, speed, altitude, and other parameters in accordance with predefined instructions or parameters.
In aviation, autopilots are integral to modern aircraft, allowing pilots to delegate routine tasks and focus on higher-level decision-making and critical flight operations. They provide efficient and precise control over the aircraft, enabling stable flight and reducing pilot workload. Autopilots can maintain a predetermined heading, follow a specific flight plan, or engage in intricate navigation procedures, including instrument approaches and landings.
Autopilot systems use various sensors, such as gyroscopes, accelerometers, altimeters, and airspeed indicators, to gather data about the vehicle's position, orientation, velocity, and other factors. This information is then processed by the autopilot's computer, which calculates the necessary adjustments to maintain the desired flight parameters. The system controls the aircraft's flight control surfaces, such as ailerons, elevators, and rudders, through actuators or servo-mechanisms, ensuring the desired course, speed, and altitude are maintained.
While autopilots enhance safety, enhance efficiency, and provide relief to pilots during long flights, they are not substitutes for human judgment and situational awareness. Pilots must remain vigilant, monitor the autopilot's operations, and be prepared to take control of the aircraft in case of emergencies or abnormal situations.
The word "autopilots" is a combination of two terms: "auto" and "pilots".
The term "auto" comes from the Greek word "αὐτός" (autós), which means "self" or "same". It is often used as a prefix in English to indicate "self-operating" or "automatic" functions.
The term "pilots", on the other hand, derives from the Middle French word "pilote", which means "ship's pilot" or "helmsman". This ultimately comes from the Latin word "pilotus", referring to the person who guides a ship or aircraft.
When combined, "autopilots" therefore refers to a system or device that can automatically control the motion or navigation of an aircraft, without needing constant manual input from a human pilot.
