Part of a larger research program studying communication in the cockpit, this study investigated the occurrence of mitigation, that is, the use of linguistic forms that convey propositional content without giving offense, and its relationship to aviation accidents. The data were from flight-recorder accident transcripts containing observable…

A study of the problems posed by the use of natural language in various aspects of aviation is presented. The study, part of a larger investigation of the feasibility of voice input/output interfaces for communication in aviation, looks at representative real examples of accidents and near misses resulting from language confusions and omissions.…

The reliability and maintainability (R&M) model described in this report represents an important portion of a larger effort called the Digital Avionics Information System (DAIS) Life Cycle Cost (LCC) Study. The R&M model is the first of three models that comprise a modeling system for use in LCC analysis of avionics systems. The total…

A research study was conducted to determine the feasibility and desirability of developing generalized training equipment for use in avionic systems maintenance training. The study consisted of a group of survey and analytic tasks to provide useful guidance to serve the needs of the Naval Aviation community in future years. The study had four…

The report documents the results of a national survey of the aviation mechanics' occupation. The study surveyed 151 companies in the four industrial categories of the aviation industry and was concerned only with the certificated airframe and powerplant mechanic. Results of the study provide the following: (1) identification of the technical…

The training requirements analysis model (TRAMOD) described in this report represents an important portion of the larger effort called the Digital Avionics Information System (DAIS) Life Cycle Cost (LCC) Study. TRAMOD is the second of three models that comprise an LCC impact modeling system for use in the early stages of system development. As…

This document describes five alternative scenarios which present various conditions that may exist in the United States from now to the year 2000, and which would be important in shaping demand for air transportation. Each scenario describes the potential evolution of various socioeconomic conditions, along with a projection of the amount and type…

Designed to identify and quantify the potential impacts of the Digital Avionics Information System (DAIS) on weapon system personnel requirements and life cycle cost (LCC), this study postulated a typical close-air-support (CAS) mission avionics suite to serve as a basis for comparing present day and DAIS configuration specifications. The purpose…

The Reliability, Maintainability, and Cost Model (RMCM) described in this report is an interactive mathematical model with a built-in sensitivity analysis capability. It is a major component of the Life Cycle Cost Impact Model (LCCIM), which was developed as part of the DAIS advanced development program to be used to assess the potential impacts…

The objective of the project was to investigate the utility of using an A/F37A-T4G T-37 flight simulator within the context of Air Force undergraduate pilot training. Twenty-one subjects, selected from three undergraduate pilot training classes, were given contact flight training in a TP4G/EPT simulator before going to T-37 aircraft for further…

The report documents the results of a national survey of book publishing firms and aviation maintenance technician schools to (1) identify the text materials used in the training of aviation mechanics; (2) appraise the suitability and availability of identified text materials; and (3) determine the adequacy of the text materials in meeting the…

This report documents an experiment to determine the training effectiveness of a microcomputer-based avionics system trainer as a cost-effective alternative to training in the actual aircraft. Participants--26 operationally qualified C-141 pilots with no prior knowledge of the Fuel Saving Advisory System (FSAS), a computerized fuel management…

This report includes three experiment sections. The first experiment tested sensitivity to loss in altitude and demonstrated that: (1) preview effects led to adaptation; (2) sensitivity decreased with higher flow rates; and (3) sensitivity increased with higher optical texture densities and fractional loss. The second and third experiments…

Flight simulators are built as realistically as possible, presumably to enhance their training value. Yet, their training value is determined by the way they are used. Traditionally, simulators have been less important for training than have aircraft, but they are currently emerging as primary pilot training vehicles. This new emphasis is an…

A national survey examined the opinions of aircraft maintenance training school administrators and instructors concerning the suitability of Federal Aviation Regulation Part 147 (FAR 147) to regulate effectively today's training programs. Responding to the mail survey instrument were 163 persons representing 90 schools in 37 states. Included among…
