Abstract The Traffic Management Advisor (TMA) is part of the FAA’s Free Flight program which has been on going for the past 12 years in an attempt to enable controllers the means in which to manage airspace and reduce delays at airports safely and more efficiently. It uses flight plan information along with environmental concerns to aide controllers in sequencing arrivals at airports and makes recommendations for traffic patterns to aide in undue congestion. The TMA has boosted efficiency of the air traffic controllers and helped in fuel efficiency and safety for the airlines, passengers and crews. The Concept of the Traffic Management Advisor The Traffic Management Advisor (TMA) is used to aide the air traffic controllers and coordinators thru graphical map, which display alerts, when dealing with aircraft when they are on the outer meter, meter fixed, final approach and threshold for landing at an airport. The TMA schedules and sequences times for their orbits and landings at airports which take a lot of the stress and calculations away from the controllers. It also schedules their landing runways for the aircraft which helps with separation and safety of the aircraft. It does this by computing their speed and approach angles which can be seen on a live Doppler type of screen. The TMA system relies on eight processes which include the following: 1) the communications manager which shares information between its databases, 2) the radar daemon which has a link between the TMA and the controllers computer, 3) the weather daemon which uses weather information from the national weather service, 4) the timeline graphical user interface which receives and uses information from the traffic management controllers computer, 5) the route analyzer which decides which route the aircraft will use, 6) the planview graphical user interface which uses input from the controllers and displays the information, 7) the trajectory synthesizer which determines the estimated time of arrival and the descent profile of the aircraft, and 8) the dynamic planner which determines the runway and the sequences of the other incoming traffic. The TMA computes the aircrafts schedule and sequencing between 40 and 200 miles from the airport, even before they have reached the airports controlled airspace. All of this information comes from the aircrafts flight plan and the TMA has the ability to adjust runway assignments and the sequencing of the aircraft also due to environmental conditions or in response to the input by the controllers.
The Metropolitan Atlanta Rapid Transit Authority (MARTA) is one of the largest transit systems in the United States. It is the ninth largest system, transporting over 550,000 passengers daily. MARTA provides bus and rapid rail service to the most of the metropolitan area of Atlanta. The transit agency was established in 1971 with the passage of an authorizing referendum by voters in Fulton and DeKalb counties and the city of Atlanta. MARTA is a public authority that operates under Georgia law. The agency is governed by a board of directors with representation from several counties including Fulton, DeKalb, Clayton, and Gwinnett as well as the city of Atlanta. MARTA has approximately 4,500 employees. The majority of MARTA's operating revenues come from fares and a sales tax from customers.
“What time should we leave? Two hours in advance? Three? Four?” Millions of people ask these questions each year before boarding a plane. Between driving, security, walking to the gate, and getting settled, boarding a plane exhausts travelers. But out of all of these different activities, one frustrates and restrains travelers the most: TSA security. People ask why they need all this security, complain about the inconvenience it causes, and ultimately annoys people to no end. Created after 9/11, Transportation Security Administration, or TSA, nationalized airport security, increased screening duration, and supposedly increases security on flights. However, statistics say these added security measures never come to fruition and potentially cost more lives than they save.
Challenged by an old, obsolete airport, the city of Denver decided on not only doing an expansion but ultimately building a fully dedicated facility in an entirely new location. Twice the size of Manhattan, the airport was to be the largest in the United States and was specially designed to handle concentrated hubbing traffic (Montealgre et al, 1996, p.4). The master plan encompassed a fast tracked build-design scheme that called for utmost operational efficiency which would consequently attract large airlines to choose DIA as their main Southwestern hub (Nice, n.d.). Dominance of the DIA would fuel an economic boom in Denver, but for this to take place—a fast passenger turnover would be required, leading to the perception that they had to implement an airport-wide automated baggage handling system in spite of the known risks. This critical piece of the airport wou...
Over $800 million is spent annually on the national Air Marshall program, but “there have been more arrests of air marshals since 9/11 (for off-duty conduct such as drunk driving) than by air marshals for conduct in airports or on planes” (Brill). Meanwhile, the number of TSA agents has been greatly reduced due to budget cuts, creating long security lines and the probability of overlooking a potential threat (Willis). These crowded areas in pre-screened areas also serve as an easy target for terrorists
Chuck Goodwin explains, “TSA, which stands for Transportation Security Administration, is an agency in the Department of Homeland Security and is responsible for screening all travelers and their luggage, as well as the screening of all air and rail transportation in the US.” Many travelers know of the them for their increased presence in all airports in the U.S and other major American airports worldwide. After the terrorist attack that took place in September 2001, President Bush and his advisors implemented The Patriot Act. Tracey DiLascio explains, “The Patriot Act is complex, but its major provisions act to improve coordination and communication between government intelligence agencies, removing unwieldy and unnecessary legal barriers between different federal offices and allowing vital investigations to proceed with greater ease and efficiency.” Their idea was to ensure that all intelligence agencies would communicate in a way that would keep America safe. “Steps to prevent events of the scale of those that took place at the World Trade Center and the Pentagon on September 11, 2001, began to fall into place almost immediately...The first outline of a proposal for what would eventually become the USA Patriot Act was drafted just days after the attacks.” (DiLascio) Due to past terrorist attacks, the TSA has implemented security measures in the airports they occupy. “Following September 11, 2001, the Transportation Security Administration (TSA) was created to strengthen the security of the nation’s transportation systems and ensure the freedom of movement for people and commerce.” (TSA website) These measures include full body scanners and pat downs.

The purpose of this paper is to describe the importance of operations management to a health care organization. In addition, the author of this paper will provide a personal definition of what operations management means and why is important to a healthcare organization.
One major organization that was created from the attacks on September 11th that lead to the declaring “War on Terror” was the creation of TSA, Transportation Security Administration. TSA was created to develop policies to protect airport transportation and prevent aircraft hijacking. It oversees security for highways, railroads, buses, mass transit systems, pipelines and ports. Though they are mostly responsible for screening passengers and checked and carry-on luggage at about 450 airports. Different types of TSA employees are; Transportation Security Officer, Federal Air Marshal, Transportation Security Inspector and National Explosives Detection Canine Team Program.

Airport planning, once carried out utilizing a single future forecast, failed to account for the complexity and uncertainty of the aviation industry. Today, it is widely assumed airport success can only be met through the utilization of a flexible, integrated planning approach that sees forecasts as incorrect.
The main opportunities that the scheduled air transportation will have in the next five years are the possible decrease of TSA agents at airports, technology increasing the safety and comfort of the flights for the passengers and ...
Flight fee is one of the biggest nightmares of the passenger. In this regard, such an initiative is a win-win situation for the Asiana airlines. The establishment of extensive cabin retrofits is also a great improvement to the customer service delivery. The airline also boosts customer experience in a bid to achieve the airline’s sustainability through the provision of lie-flat seats. The seats boost comfort for the passengers aboard; hence, reduction of exhaustion. According to Asian Development Bank (2009), the airline provides the passengers with a sizeable monitor, especially for the business class passengers. The practical productivity of team relies on upon its hypothetical planning, information of an aeronautical building, and tenets of its operation, including exceptional circumstances, and propensities for utilization of this learning, furthermore on order and determination of pilot-in-charge of aircraft and group individuals. The administration productivity air movement, the associations of flight action and a wide range of upkeep of aircraft in the greatest degree is controlled by the proficiency of the action association in the modern undertakings, cognizance of initiators, and the moral obligation of leaders of all positions for action concerning security control of
Operations management focuses on managing the processes of producing and distributing products and services. Operations activities often include product creation, development, production and distribution. It deals with all operations within the organization. Related activities include managing purchases, inventory control, quality control, storage, logistics and evaluations. The nature of how operations management is carried out in an organization depends very much on the nature of products or services in the organization, for example, retail, manufacturing, wholesale, etc.
Airports are vast facilities covering many acres of land where passenger beginning the flight portions of their travels. The first flight by the Wright brothers in Kitty Hawk, NC in 1903 only required a runway. As the technology of flight advanced to offer passenger service, there was soon a need for a building to manage passenger needs. Airports of today provide many key services needed for the traveler whether they are beginning, transferring, or ending their journeys. The demand for air transportation rises each year, according to the Department of Transportation (United States Department of Transportation, 2013) 815.3 passengers traveled by airplanes in 2012. With the demand expected to rise, airports must be able to keep pace with services. There are many different services provided however, this report will discuss terminal design, baggage handling, and ground access.
Flight management systems are one of the best navaids in commercial aviation. The flight management system (FMS) is made up of four systems in an aircraft, the FMC (flight management computer), the autopilot and flight director, the auto throttle, and the IRS’s. According to Boeing the FMS could be defined as, being capable of four dimensional area navigation (latitude, longitude, altitude, and time), while optimizing performance to achieve the most economical flight possible. The flight management system can give you gross weight of the aircraft, and the best speeds (i.e. holding, approach, climb, cruise, descent, etc…) by taking inputs from the fuel summation unit when it is given the zero fuel weight and the MACTOW (mean aerodynamic cord at takeoff weight). The position of the aircraft can also be determined by referencing the IRS, along with GPS and the radio position updating.
During the planning process, outputs are created to illustrate how project tasks will be sequenced and allocated for effective TM. The PMBOK Guide describes nine processes under Project Time Management (Fig 2.) all of which (excluding no. 6) are relevant during the planning phase of the project life cycle.
