A primary mission of the Federal Aviation Administration (FAA) is the assurance of safety in civil aviation, both private and commercial. To accomplish this mission, the FAA has promulgated a large number of regulations and has established a major division, the Office of Aviation Safety, to enforce and maintain the regulations and effectively promote safety in aviation. Within the office there are several subordinate organizations. Staffing Standards for Aviation Safety Inspectors is concerned with two of them: the Flight Standards Service (called AFS), charged with overseeing aviation operations and maintenance, as well as other programs, and the Aircraft Certification Service (AIR), charged with ensuring the safety of aircraft through regulation and oversight of their design and manufacture. The objective of the study is to determine the strengths and weaknesses of the methods and models that the FAA now uses in developing staffing standards and projections of staffing needs for ASIs and to advise the FAA on potential improvements. Staffing Standards for Aviation Safety Inspectors is organized in an Executive Summary and five chapters. This first chapter provides the background of the study and explains the committee's approach to its task. Chapter 2 discusses modeling and its applicability to the development of staffing standards for such organizations as the Flight Standards Service and the Aircraft Certification Service. Chapter 3 traces the recent history of staffing standards in these organizations and considers manpower and staffing models and methods used by other organizations. Chapter 4 examines factors to be considered in the development of ASI staffing standards and the challenges faced by any methodology applied to this task. Chapter 5 presents the committee's findings and recommendations, including a discussion of issues and constraints that must be considered in weighing the implementation of alternative approaches.

Within the Federal Aviation Administration (FAA), the Airway Transportation System Specialists ATSS) maintain and certify the equipment in the National Airspace System (NAS).In fiscal year 2012, Technical Operations had a budget of $1.7B. Thus, Technical Operations includes approximately 19 percent of the total FAA employees and less than 12 percent of the $15.9 billion total FAA budget. Technical Operations comprises ATSS workers at five different types of Air Traffic Control (ATC) facilities: (1) Air Route Traffic Control Centers, also known as En Route Centers, track aircraft once they travel beyond the terminal airspace and reach cruising altitude; they include Service Operations Centers that coordinate work and monitor equipment. (2) Terminal Radar Approach Control (TRACON) facilities control air traffic as aircraft ascend from and descend to airports, generally covering a radius of about 40 miles around the primary airport; a TRACON facility also includes a Service Operations Center. (3) Core Airports, also called Operational Evolution Partnership airports, are the nation's busiest airports. (4) The General National Airspace System (GNAS) includes the facilities located outside the larger airport locations, including rural airports and equipment not based at any airport. (5) Operations Control Centers are the facilities that coordinate maintenance work and monitor equipment for a Service Area in the United States. At each facility, the ATSS execute both tasks that are scheduled and predictable and tasks that are stochastic and unpredictable in. These tasks are common across the five ATSS disciplines: (1) Communications, maintaining the systems that allow air traffic controllers and pilots to be in contact throughout the flight; (2) Surveillance and Radar, maintaining the systems that allow air traffic controllers to see the specific locations of all the aircraft in the airspace they are monitoring; (3) Automation, maintaining the systems that allow air traffic controllers to track each aircraft's current and future position, speed, and altitude; (4) Navigation, maintaining the systems that allow pilots to take off, maintain their course, approach, and land their aircraft; and (5) Environmental, maintaining the power, lighting, and heating/air conditioning systems at the ATC facilities. Because the NAS needs to be available and reliable all the time, each of the different equipment systems includes redundancy so an outage can be fixed without disrupting the NAS. Assessment of Staffing Needs of Systems Specialists in Aviation reviews the available information on: (A) the duties of employees in job series 2101 (Airways Transportation Systems Specialist) in the Technical Operations service unit; (B) the Professional Aviation Safety Specialists (PASS) union of the AFL-CIO; (C) the present-day staffing models employed by the FAA; (D) any materials already produced by the FAA including a recent gap analysis on staffing requirements; (E) current research on best staffing models for safety; and (F) non-US staffing standards for employees in similar roles.

THE ESSENTIAL WORK IN TRAVEL MEDICINE -- NOW COMPLETELY UPDATED FOR 2018 As unprecedented numbers of travelers cross international borders each day, the need for up-to-date, practical information about the health challenges posed by travel has never been greater. For both international travelers and the health professionals who care for them, the CDC Yellow Book 2018: Health Information for International Travel is the definitive guide to staying safe and healthy anywhere in the world. The fully revised and updated 2018 edition codifies the U.S. government's most current health guidelines and information for international travelers, including pretravel vaccine recommendations, destination-specific health advice, and easy-to-reference maps, tables, and charts. The 2018 Yellow Book also addresses the needs of specific types of travelers, with dedicated sections on: · Precautions for pregnant travelers, immunocompromised travelers, and travelers with disabilities · Special considerations for newly arrived adoptees, immigrants, and refugees · Practical tips for last-minute or resource-limited travelers · Advice for air crews, humanitarian workers, missionaries, and others who provide care and support overseas Authored by a team of the world's most esteemed travel medicine experts, the Yellow Book is an essential resource for travelers -- and the clinicians overseeing their care -- at home and abroad.
