Synthesized voice approach callouts for air transport operations by Carol A Simpson( )

4 editions published in 1980 in English and held by 348 WorldCat member libraries worldwide

A flight simulation experiment was performed to determine the effectiveness of synthesized voice approach callouts for air transport operations. Flight deck data was first collected on scheduled air carrier operations to describe existing pilot-not-flying callout procedures in the flight context and to document the types and amounts of other auditory cockpit information during different types of air carrier operations. A flight simulation scenario for a wide-body jet transport airline training simulator was developed in collaboration with a major U.S. air carrier and flown by three-man crews of qualified line pilots as part of their normally scheduled recurrent training. Each crew flew half their approaches using the experimental synthesized voice approach callout system (SYNCALL) and the other half using the company pilot-not-flying approach callout procedures (PNF). Airspeed and sink rate performance was better with the SYNCALL system than with the PNF system for non-precision approaches. For the one-engine approach, for which SYNCALL made inappropriate deviation callouts, airspeed performance was worse with SYNCALL than with PNF. Reliability of normal altitude approach callouts was comparable for PNF on the line and in the simulator and for SYNCALL in the simulator

Comparison of Speech Intelligibility in Cockpit Noise Using SPH-4 Flight Helmet with and without Active Noise Reduction( Book )

2 editions published in 1990 in English and held by 2 WorldCat member libraries worldwide

Active Noise Reduction (ANR) is a new technology which can reduce the level of aircraft cockpit noise that reaches the pilot's ear while simultaneously improving the signal-to-noise ratio for voice communications and other information-bearing sound signals in the cockpit. A miniature, ear-cup mounted ANR system, developed by Royal Aerospace Establishment, Farnborough, United Kingdom, was tested by U.S. Army Aeroflightdynamics Directorate, Simulation and Aircraft Systems Division, Crew Station Research and Development Branch to determine whether speech intelligibility is better for helicopter pilots using ANR compared to a control condition of ANR turned off. The ANR system was installed in a stock Army SPH-4 flight helmet, and tested in a background of recorded AH-1S (Cobra) cockpit noise, using phonetically balanced word lists, per MIL-STD-1472C. Two signal-to-noise ratios (S/N), representative of actual cockpit conditions, were used: 0 dB and +10 dB for the ratio of the speech to cockpit noise sound pressure levels. Speech intelligibility was significantly better with ANR compared to no ANR for both S/N conditions. Variability of speech intelligibility among pilots was also significantly less with ANR. When the stock helmet was used with ANR turned off, the average PB word speech intelligibility score was below the Normally Acceptable level, per MIl-STD-1472C in the 0 dB S/N levels and exceeded the Exceptionally High Intelligibility level with S/N +10 dB. Keywords: Cockpit communications, Active noise reduction
Program Graphic by Carol A Simpson( Book )

2 editions published in 1973 in English and held by 2 WorldCat member libraries worldwide

Program GRAPHIC plots data generated by the CUMLIQ cumulus dynamic model. It uses the FNWC 6500 Varian Plot routines to generate a file on PLOT (a disc file internal to the FNWC 6500 system) which then drives the Varian plotter

Evaluation of Speech Recognizers for Use in Advanced Combat Helicopter Crew Station Research and Development( )

1 edition published in 1990 in English and held by 1 WorldCat member library worldwide

The U.S. Army Crew Station Research and Development Facility uses vintage 1984 speech recognizers. An evaluation was performed of newer off-the- shelf speech recognition devices to determine whether newer technology performance and capabilities are substantially better than that of the Army's current speech recognizers. The Phonetic Discrimination (PD-100) Test was used to compare recognizer performance in two ambient noise conditions: quiet office and helicopter noise. Test tokens were spoken by males and females and in isolated-word and connected-word mode. Better overall recognition accuracy was obtained from the newer recognizers. The report lists recognizer capabilities needed to support the development of human factors design requirements for speech command systems in advanced combat helicopters
