  • Runway Safety Spring 2021 Report
    Graphical NOTAM Interface For Improving Efficiency of Reporting NOTAM Information April 2021 Design Challenge: Runway Safety/Runway Incursions/Runway Excursions Challenge E: Optimizing application of NextGen technology to improve runway safety in particular and airport safety in general. Team Members: Undergraduate Students: Matthew Bacon, Gregory Porcaro, Andrew Vega Advisor’s Name: Dr. Audra Morse Michigan Technological University Table of Contents | 1 02 Executive Summary Runway excursions are a type of aviation incident where an aircraft makes an unsafe exit from the runway. According to the Ascend World Aircraft Accident Summary (WAAS), 141 runway excursion accidents involving the Western-built commercial aircraft fleet occurred globally from 1998 to 2007, resulting in 550 fatalities; 74% of landing phase excursions were caused by either weather-related factors or decision-making factors (Ascend, 2007). One mitigation strategy is training pilots how to interpret Runway Condition Codes (RWYCCs) to understand runway conditions. Recent developments such as NextGen and Electronic Flight Bags (EFBs) have improved the quality of weather condition reporting. However, Notices to Airmen (NOTAMs), the primary source of runway condition information and any other irregularities in airspace, are still presented to pilots in an inefficient format contributing to runway excursions and safety concerns NOTAMs consist of confusing abbreviations and do not effectively convey the relative importance of information. The team developed an Electronic Flight Bag (EFB) user interface that provides a graphical representation of NOTAM and weather information to improve how pilots receive condition changes at airports. The graphical NOTAM interface utilizes Automatic Dependent Surveillance-Broadcast (ADS-B) to receive real time NOTAM updates.

  • Capstone Program Plan (Draft)
    DRAFT Federal Aviation Administration Alaskan Region Capstone Program Management Office 801 B Street, Suite 500 Anchorage, Alaska 99501 Capstone Program Plan DRAFT Version 3.0 12 June 2001 ALASKAN REGION Investment in Safety DRAFT PREAMBLE This document is designed as an umbrella program plan for the Federal Aviation Administration (FAA) Alaskan Region Capstone Program. The term umbrella, as it is used here, means the contents are intended to create high level objectives from which detailed work plans can be developed and accomplished. Each organization that accepts tasking under a particular objective or element takes with it the responsibility for developing a work plan, generating procedures for participants to use their element, and for recording and reporting the progress made toward validation. To accommodate future developments facilitated by the Capstone Program efforts, the number and the date of each successive program plan version is printed on the cover. This Capstone Program Plan version 3.0 is complimentary to Versions 1.0 and 2.0. These previous versions established the initial Capstone avionics and ground infrastructure. Version 3.0 documents the activities supporting the infrastructure in the Bethel/Yukon-Kuskokwim delta area, planning for expansion to Juneau/Southeast Alaska, and establishing ties to future implementation work, with the main focus on FY 2001. DRAFT EXECUTIVE SUMMARY The Capstone Program accelerates efforts to improve aviation safety and efficiency through a multi-year introduction of current and emerging concepts and technologies. According to information published by the National Institute for Occupational Safety and Health, accident rates in Alaska are elevated up to 400 percent above the national average.

    NOTAMs Back to Basics: Airports Federal Aviation Administration NOTAMs Affect All Users of the NAS ICAO Flight U.S. Service NOTAM Flight Stations Office Inspection Flight Dispatch Air Instrument Wild Fire Pilot Traffic Approach Fighting Control Procedure Office Service DOD Centers Technical ATO Operations Security Technician Airport General Operator Public Information valid through Federal Aviation 2 December 2018 Administration A NOTAM is a notice containing information essential to personnel concerned with flight operations but not NOTAM known far enough in advance to be publicized by other means. NOTAMs concern the establishment, condition, or change of any component (facility, service, procedure, or hazard) in the NAS. They must state the abnormal status of a component of the NAS — not the normal status. In 1947, it was agreed to begin issuing NOTAMs via telecommunications. NOTAMs were modeled after Notice to Mariners, which advised ship captains of hazards in navigating the high seas. Information valid through Federal Aviation 3 December 2020 Administration NOTAM Contractions NOTAMs have a unique language characterized by the use of specialized contractions. Contractions are imperative to the NOTAM structure because they make communication more efficient and allow computer systems to parse important words. The International Civil Aviation Organization (ICAO) is the leading authority for standardizing contractions in the international aeronautical community. If there is no ICAO contraction, plain language is used.

    SADIS MANAGEMENT REPORT 2005-2006 WAFC LONDON March 2006 FOREWORD F.1 In the final report of the SADISOPSG/2, Paragraph 2.10 and Conclusion 2/3 placed the following action on the United Kingdom as the provider State of SADIS. F.2 ‘In order to extend the future annual reviews of the operational efficacy of the SADIS in step with the increase in SADIS VSAT installations, it was agreed that: a) ICAO should solicit the opinion of user States/users prior to each SADISOPSG meeting and report on the results to the group; and b) The service provider should be requested to provide annual Management reports prior to each SADIS meeting. F.3 This management report by the United Kingdom attempts to meet this requirement. Diagrams and other relevant documents are included in a series of Annexes to the report. F.4 A summary of the year’s main events is provided at the beginning of the report. Further detail is given in the individual sections or in working papers and information papers to be presented at SADISOPSG/11. Richard Orrell WAFC London March 2006 2 EXECUTIVE SUMMARY: YEAR 2005 TO 2006 E.1 Growth in the use of SADIS during the past 12 months has resumed. Six new users have been approved. This represents the largest annual increase since year 2001-02. Three of these new users have chosen to access their data via the SADIS FTP Service only and do not have the intention of purchasing a SADIS 2G VSAT.

  • Notams Getting Back to Basics
    NOTAMs Getting Back to Basics Federal Aviation Administration Overview Background Audience NOTAM Components Classes of NOTAMs Unique NOTAMs Frequently Asked Questions References Information valid through Federal Aviation 2 December 2018 Administration Background The Federal Aviation Administration (FAA) is committed to permanent, measurable risk reduction in the National Airspace System (NAS). The Top 5 is derived from the output of our national Quality Assurance efforts. It is the culmination of our proactive approach to safety management, which identifies the hazards that contribute to the highest risks identified each year. A cross-section of FAA representatives from the field come together for the Safety Roundtable to select the Top 5. To do so, the team reviews data extracted from high-risk airborne, surface, and technical functionality events, mandatory and electronic occurrence reports, direct feedback from facilities, Voluntary/Confidential Safety Reports, accident and National Transportation Safety Board data, and data from other sources. 1,930,385 Total number of National, International, Military and Flight Data Center (FDC) NOTAMs created between January 1, 2016, and December 31, 2016. Information valid through Federal Aviation 3 December 2018 Administration Top 5 NOTAM Initiatives In 2017, two of the five Safety Initiatives pertained specifically to Notices to Airmen (NOTAMs) issues within the NAS: 1.) NOTAM Issuance/Cancellation - Lack of, untimely, or outdated NOTAM in the system 2.) NOTAM Prioritization/Filtering - Inability of ATC or pilots to distinguish between applicable or pertinent NOTAMs. Information valid through Federal Aviation 4 December 2018 Administration Who Is Affected by NOTAMs? Every user of the NAS is affected by NOTAMs because they indicate the real-time status of the NAS.
