GENERAL DESCRIPTION

Autopilot is an automatic flight control system that keeps an aircraft in level flight or on a set course. It can be directed by the pilot, or it may be coupled to a radio navigation signal. Autopilot reduces the physical and mental demands on a pilot and increases safety. The common features available on an autopilot are altitude and heading hold.
The simplest systems use gyroscopic attitude indicators and magnetic compasses to control servos connected to the flight control system. The number and location of these servos depends on the complexity of the system. For example, a single-axis autopilot controls the aircraft about the longitudinal axis and a servo actuates the ailerons. A three-axis autopilot controls the aircraft about the longitudinal, lateral, and vertical axes. Three different servos actuate ailerons, elevator, and rudder. More advanced systems often include a vertical speed and/or indicated airspeed hold mode. Advanced autopilot systems are coupled to navigational aids through a flight director.
The autopilot system also incorporates a disconnect safety feature to disengage the system automatically or manually. These autopilots work with inertial navigation systems, global positioning systems (GPS), and flight computers to control the aircraft. In fly-by-wire systems, the autopilot is an integrated component.
Additionally, autopilots can be manually overridden. Because autopilot systems differ widely in their operation, refer to the autopilot operating instructions in the Airplane Flight Manual or the Pilot’s Operating Handbook. PURPOSE

i. Autopilot reduces the fatigue of the crew on long flights by taking over the routine flight control of the aircraft at any time. ii. A single-axis autopilot manages just one set of controls, usually the ailerons. This simple type of autopilot is known as a "wing leveler"…...

Brief: Leveraging Healthcare It to Improve Operational Performance

...actions that help with process flow. Intelligence is essential in the level and most healthcare IT systems are not capable of processing this. Basic automation is the next level, which also includes work reduction. This includes completing forms, orders, and notes and moving them from manual to an automated process. As a result, work from workers will be taken away to ensure the required processes are fulfilled. Global positioning system (GPS) is the next level and this basically guides users through the care process. This is where one will find the protocol for certain procedures. The GPS-plus level exceeds the GPS level in that human intervention is not needed. The final level is the “autopilot” level, which is when an entire function or process can be handled by the workflow system. The autopilot level is the gold standard for business process management. A major concern at the Chester County Hospital (CCH) is patient safety; particularly with infections. Since MRSA has been receiving a lot of attention for the past several years, it has been a focal point of CCH to control. Developing a MRSA workflow lead to a reduction of MSRA infections and an increase in total awareness of other contagious infection workflow. This study shows that the health care systems of today can benefit from workflow technology. It improves productivity and optimizes processes to enhance patient experience. The potential of uncovering the true value of healthcare IT can be obtained through......

Chapter 4 Change Management Part

...The Choice to Be a Conscious Change Leader Now that we have a common understanding of the functioning of conscious awareness and autopilot, we can discuss what we mean by taking a conscious approach versus an autopilot approach to leading transformation. Remember, we all have both of these mental capabilities and we fluctuate continually between them, sometimes operating with conscious awareness and other times operating on autopilot. Taking a conscious approach to leading transformation does not mean, then, always operating with conscious awareness. Similarly, taking an autopilot approach does not mean always operating on autopilot. What is the diff erence then between these two very different types of leaders — the conscious change leader and the autopilot change leader? Conscious change leaders are just that because they choose to be, and they make a significant personal commitment to how they operate as human beings and leaders. Conscious change leaders turn inward, introspect, and put their attention on their inner awareness and mindset, and their intention on proactively developing their innermost being. In our language, they “ put their being first. ” Ā ey seek greater self - awareness and understanding because they know that their level of awareness and mindset influence everything about their lives and leadership. Ā ey seek to develop their own level of consciousness so they can operate at the highest levels possible, and therefore, contribute fully. Ā ey......

Accuair Swot

...Their technology would help greatly in the aero industry because an airbag weighs less than a metal shock or spring. B. Second Opportunity- Introducing their technology to the automotive industry to come standard on new cars is another great opportunity. They should also start to make air suspension for mountain bikes as well. 18-wheeler tractor-trailers can also benefit from Accuair’s technology. It also makes for a comfortable ride and holds so much more weight for hauling etc. C. First Threat-Accuair’s biggest threat is a company called Autopilot V2. They have their own technology, which uses sensors in all four corners to send a signal to the brain of the system and give it up to the millisecond information about your vehicle and its ride height. It automatically compensated for added weight anywhere in the car to keep the same ride height within a second. It also levels the car out when turning and swaying. Autopilots system is also a little lower on price compared to the same system Accuair has. D. Second Threat- Other air suspension manufacturers offer rebates and discounts. Accuair is firm to the t on their prices and I will go out on a limb and say they are proud. So far, it has worked for them, or maybe it has not. I know that you cannot put a price on quality, but many customers will beg to differ. I feel that if they do not offer incentives or lower prices they will eventually reach a plateau in sales. IV. Summary Accuair needs to reevaluate......

How Smart, Connected Products Are Transforming Companies

...is basically a storage facility for all data that is collected. Once it makes it to the data lake, it then takes one of several premade routes to its final destination for data interpretation. One setback to becoming a smart device oriented company is the change in infrastructure that is required. Once you have started using these data collection processes, you must now create servers that can hold all of the information gathered. This can be an expensive process. Not only do you have to buy the servers, but you must also invest in the security for said products. Take airlines for example. The airplane is always on autopilot above 18000 feet. Autopilot is a great technology and can oftentimes fly the aircraft more precisely than a human can. However, if there had been no investment in security by the companies in charge of creating autopilots, there could be many more hijackings that are even accomplished remotely. Another concern that is involved in these smart products is outsourcing. We see it with many different companies already. Technical support is a very common department to outsource. It oftentimes costs much less to outsource to other countries than it is to have staff on site that are dedicated to these easily outsourced functions. With the increase in connectivity it will become easier and easier to outsource to these different countries. Many times it is possible for these technical support departments to remotely take control of these smart......

Free Will

...identity. This specific example only demonstrates three-quarters of the unpredictable formula behind a human person’s external reactions (e.g. laughter when something humorous occurs, violence in response to a person who poses a threat, or conversation initiated between two strangers). The question that must now be examined is, “what is it that makes a person transform their internal intention into a bodily movement or action?” The intellect is not fully passive. Just because the person’s internal response was a confidence boost and a desire to interact with the stranger does not indicate that they will automatically surrender to their desire. The person must make a conscious effort to take action, as not all action occurs on autopilot. An example of an “autopilot” reaction would be a simple hand-withdrawal reflex that requires no cognitive appraisal. For instance, when a person’s hand jerks away from a candle flame, this occurs with little intellectual choice. The hand jerks away, not because the person desires to stop sensing pain and decides to move their hand away, but because sensory neurons carried information from the skin receptors to the spinal cord and from there, the spinal cord passed the information to motor neurons leading to the hand and arm muscles— all in a matter of seconds (Myers, p. 59, 2013). It cannot be argued that not every physical action is automatic, therefore, it is crucial to examine the concept of active choice after a cognitive appraisal, such......

...resulted in the plane crash. The pilot reacted professionally to the warning signal—he executed a command that retracted the hanging flaps. It was then that a strange sound was heard from the cockpit voice recorder. A roll excursion not commanded disengaged the autopilot mode. While the pilot regained the control of the plane after the first roll, a second roll occurred, resulting in a steep descent of the airplane. It took less than 30 seconds for the contact with the aircraft to be lost. The authorities would later confirm the worst fears—68 souls were lost as the plane plunged into Soybean, Indiana. The Cause of Plane Accident The investigation team found out that the ATR planes manufacturer did not design them to operate in icy conditions. Stephen Fredrick ( ATR employee) revealed that the firm bypassed the safety measures, resulting in the fatal crash. In addition, the National Transport Safety Board blamed FAA (Federal Aviation Administration) for its failure in ensuring highest level of safety for air travelers. The loss of aircraft control was due to an abrupt aileron hinge reversal due to ice accumulation (Lintern, 2000). The hinge failure resulted in the rolling of the plane and the steep descent because autopilot procedures were unnecessary. However, ATR failed to incorporate an appropriate command for adoption in pilot manuals to ensure safety during such weather conditions. The accident was preventable. FAA should have ensured that adequate pilot......

Employee Silence

...employers the damages that an employee’s silence only promotes detrimental factors for an organisations’ future. Although employers do not purposely create a fear factor for the employees, the most frequently mentioned reason for remaining silent was the fear of being viewed or labelled negatively (Milliken, 2003 p.2). With the employees supressing of information it can lead to the rise of poorly planned projects and the loss of potential innovation that could drastically benefit the organisation. Furthermore, employee silence not only negatively affects the organisation but also affects the employees, causing the development feeling unvalued, a lack of control and a cognitive dissonance (Jacobsen 2014) from the workplace and a sensation of autopilot, these could produce slack and disregardful behaviour. (danaghey et al, 2011). A contributing factor to employee silence is the widely used closed-office layout in which each employee is given their own booth to work in individually with communication occurring behind the screen. This encourages employees to close themselves off from other colleagues and discourages them from making direct contact with their work force. Another common mistake made by many senior staff members is that they assume that talking to the employee's direct supervisor and/or thinking that a downward communication is enough, (Forbes, 2014) however this creates the atmosphere of a closed-door environment where employees are too afraid to approach their......

Aircraft Control Systems

...pilot a perfect opportunity to lose altitude with gaining extreme speed (Federal Aviation Administration). Autopilot It is a flight control system that maintains a plane in level flight or on a set course. The flight control system does not rely on a pilot for navigation since the plane can be fitted with a radio navigation signal. It has similar characteristics of the fly-by-wire control system thus is very safe since the physical and mental demands of the pilot are reduced. The major factors associated with autopilot are altitude and heading hold. According to the Federal Aviation Administration, the most common autopilot systems use gyroscopic altitude indicators and magnetic compasses to regulate the servos connected to the aircraft’s control system. The number of the servos relies on the convolution of the system. More complicated autopilot systems constitute a vertical speed and can include or exclude an air speed hold mode. Complicated autopilot systems are connected to navigational aids via flight directors. Autopilot systems comprise a disconnect safety feature whose main purpose is to disconnect the system automatically or manually depending on the flight’s control system. For a fly-by-wire flight control system, autopilot is an inbuilt feature which is utilized when necessary (Federal Aviation Administration). The main components required to have a profound autopilot control system are inertial navigation systems, global positioning systems and flight computers......

Unmanned Helicopter Programming

...works by detecting thermal infrared radiation, or radiated heat. Several autopilots and FPV (First Person View) -assist systems have been based on this type of sensor, as it is practical for a fixed-wing plane without using GPS or expensive drift-prone IMUs (Inertial Measurement Units). They range from sophisticated surveillance drones that detect threats in an environment, to backyard remote helicopters for recreation and practice. The basic design for any remote vehicle includes the guidance systems, power source, control systems, flight surfaces, and if needed, an autopilot program. I intend to learn more about designing and fabricating remote helicopter so that I may design and fabricate my own radio controlled helicopter. The most common power source of radio control helicopters are Lithium Polymer batteries. A thermopile is a horizon sensor that works by detecting thermal infrared radiation, or radiated heat. First Person View (FPV), also known as Remote Person View (RPV) or Video Piloting, is a method used to control a radio controlled model vehicle from the driver or pilot's view point. Digital servos are more effective but use more power in their outputs. The main difference is that digital servos use electronic circuits to utilize more power for greater control. The key to any radio control helicopter is a dedicated autopilot system. An innovative do-it-yourself autopilot is the Arduino Uno autopilot, to which you can build circuits, programs, etc. to perform......

Auto

...AUTOPILOT An autopilot is a mechanical, electrical, or hydraulic system used to guide a vehicle without assistance from a human being. An autopilot can refer specifically to aircraft, self-steering gear for boats, or auto guidance of space craft and missiles. The autopilot of an aircraft is sometimes referred to as "George", after one of the key contributors to its development HISTORY OF AUTOPILOT MECHANISAM: In the early days of aviation, aircraft required the continuous attention of a pilot in order to fly safely. As aircraft range increased allowing flights of many hours, the constant attention led to serious fatigue. An autopilot is designed to perform some of the tasks of the pilot. The first aircraft autopilot was developed by Sperry Corporation in 1912. The autopilot connected a gyroscopic Heading indicator and attitude indicator to hydraulically operated elevators and rudder (ailerons were not connected as wing dihedral was counted upon to produce the necessary roll stability.) It permitted the aircraft to fly straight and level on a compass course without a pilot's attention, greatly reducing the pilot's workload. Lawrence Sperry (the son of famous inventor Elmer Sperry) demonstrated it two years later in 1914 at an aviation safety contest held in Paris. At the contest, Sperry demonstrated the credibility of the invention by flying the aircraft with his hands away from the controls and visible to onlookers of the contest. This autopilot system was also capable...
