FAA) Privacy Impact Assessment Service Availability Prediction Tool (SAPT)
U.S. Department of Transportation Federal Aviation Administraiton (FAA) Privacy Impact Assessment Service Availability Prediction Tool (SAPT) Responsible Official David E. Gray Program Manager [email protected] Approving Official Claire W. Barrett Chief Privacy & Information Asset Officer Office of the Chief Information Officer [email protected] 0 U.S. Department of Transportation Executive Summary On May 28, 2010, the Federal Aviation Administration (FAA) published the Automatic Dependent Surveillance – Broadcast (ADS-B) final rule mandating that aircraft flying in certain controlled airspace be equipped with ADS-B Out capability not later than January 1, 2020.1 In turn, the FAA developed the Service Availability Prediction Tool (SAPT) to assist pilots, dispatchers, and commercial operators in checking their predicted navigation and surveillance availability before a flight as well as handle requests for Air Traffic Control (ATC) authorization pursuant to 14 CFR § 91.225(g). The SAPT has three main components: Receiver Autonomous Integrity Monitoring (RAIM) SAPT, Automatic Dependent Surveillance-Broadcast (ADS-B) SAPT, and ADS-B Deviation Authorization Pre-Flight Tool (ADAPT). This Privacy Impact Assessment (PIA) was developed pursuant to Section 208 of the E-Government Act of 2002 because the SAPT includes a web-based capability to collect and manage Personally Identifiable Information (PII) captured from aircraft operators to facilitate the automated handling of ATC authorization requests and FAA’s responses. What is a Privacy Impact Assessment? The Privacy Act of 1974 articulates concepts for how the federal government should treat individuals and their information and imposes duties upon federal agencies regarding the collection, use, dissemination, and maintenance of personally identifiable information (PII). -

A Review of Current Research in Subscale Flight Testing and Analysis of Its Main Practical Challenges
aerospace Article A Review of Current Research in Subscale Flight Testing and Analysis of Its Main Practical Challenges Alejandro Sobron * , David Lundström and Petter Krus Department of Management and Engineering, Division of Fluid and Mechatronic Systems, Linköping University, SE-58183 Linköping, Sweden; [email protected] (D.L.); [email protected] (P.K.) * Correspondence: [email protected]; Tel.: +46-1328-1893 Abstract: Testing of untethered subscale models, often referred to as subscale flight testing, has traditionally had a relatively minor, yet relevant use in aeronautical research and development. As recent advances in electronics, rapid prototyping and unmanned-vehicle technologies expand its capabilities and lower its cost, this experimental method is seeing growing interest across academia and the industry. However, subscale models cannot meet all similarity conditions required for simulating full-scale flight. This leads to a variety of approaches to scaling and to other alternative applications. Through a literature review and analysis of different scaling strategies, this study presents an overall picture of how subscale flight testing has been used in recent years and synthesises its main issues and practical limitations. Results show that, while the estimation of full-scale characteristics is still an interesting application within certain flight conditions, subscale models are progressively taking a broader role as low-cost technology-testing platforms with relaxed similarity constraints. Different approaches to tackle the identified practical challenges, implemented both by the authors and by other organisations, are discussed and evaluated through flight experiments.

+ Part 10: Test and Evaluation
10. Test and Evaluation 10.1 Approach Architecture Design, Development, Test, and Evaluation (DDT&E) schedule, costs, and risk are highly dependent on the integrated test and evaluation approach for each of the major elements. As a part of the Exploration Systems Architecture Study (ESAS), a top-level test and evaluation plan, including individual flight test objectives, was developed and is summarized in this section. The test and evaluation plan described here is derived from the Apollo Flight Test Program of the 1960s. A more detailed test and evaluation plan will be based on detailed verification requirements and objectives documented in specifications and verification plans. In order to support schedule, cost, and risk assessments for the reference ESAS architecture, an integrated test and evaluation plan was developed to identify the number and type of major test articles (flight and ground) and the timing and objectives of each major flight test, including facilities and equipment required to support those tests. This initial plan is based on the Apollo Program and the ESAS Ground Rules and Assumptions (GR&As)—including the human- rating requirements from NASA Procedural Requirements (NPR) 8705.2A, Human-Rating Requirements for Space Systems. 10. Test and Evaluation 645 10.2 Ground Rules and Assumptions ESAS GR&As establish the initial set of key constraints to testing. Although all ESAS GR&As are considered, the specific ones listed below are particularly significant, as they deal with schedule and testing/qualification assumptions. • The crew launch system shall facilitate crew survival using abort and escape. There will be three all-up tests of the Launch Abort System (LAS). -

National Transportation Safety Board Aviation Accident Final Report
National Transportation Safety Board Aviation Accident Final Report Location: Morristown, NJ Accident Number: ERA12FA115 Date & Time: 12/20/2011, 1005 EST Registration: N731CA Aircraft: SOCATA TBM 700 Aircraft Damage: Destroyed Defining Event: Loss of control in flight Injuries: 5 Fatal Flight Conducted Under: Part 91: General Aviation - Personal Analysis Although the pilot filed an instrument flight rules flight plan through the Direct User Access Terminal System (DUATS), no evidence of a weather briefing was found. The flight departed in visual meteorological conditions and entered instrument meteorological conditions while climbing through 12,800 feet. The air traffic controller advised the pilot of moderate rime icing from 15,000 feet through 17,000 feet, with light rime ice at 14,000 feet. The controller asked the pilot to advise him if the icing worsened, and the pilot responded that he would let them know and that it was no problem for him. The controller informed the pilot that he was coordinating for a higher altitude. The pilot confirmed that, while at 16,800 feet, "…light icing has been present for a little while and a higher altitude would be great." About 15 seconds later, the pilot stated that he was getting a little rattle and requested a higher altitude as soon as possible. About 25 seconds after that, the flight was cleared to flight level 200, and the pilot acknowledged. About one minute later, the airplane reached a peak altitude of 17,800 feet before turning sharply to the left and entering a descent. While descending through 17,400 feet, the pilot stated, "and N731CA's declaring…" No subsequent transmissions were received from the flight.
