Book Description
"Abstract: Data Comm -- a text-based controller-pilot communication system -- is critical to many NextGen improvements. With Data Comm, communication becomes a visual task. Interacting with a visual Data Comm display may yield an unsafe increase in head-down time, particularly for single-pilot operations. This study examined the feasibility of supplementing Data Comm with synthetic speech. To this end, thirty-two pilots flew two experimental scenarios in a Cessna 172 Flight Training Device. In one scenario, ATC communication was with a text-only Data Comm display, in the other, communications was with a text Data Comm display with synthetic speech that read aloud each message (i.e., text+speech). Pilots heard traffic with similar call signs on the party line and received a conditional clearance (in both scenarios); in either scenario, pilots received a clearance that was countermanded by a live controller. Results indicated that relative to the text-only display, the text+speech display aided single-pilot performance by reducing head-down time, and may have prevented participants from acting early on the conditional clearance. Supplementing text Data Comm with speech did not introduce additional complications: participants were neither more likely to erroneously respond to similar call signs, nor to ignore a live ATC voice countermand."--Technical report documentation page.

Book Description
Abstract: Data Comm- a text-based controller-pilot communication system- is expected to yield several NextGen safety and efficiency benefits. With Data Comm, communication becomes a visual task, and may potentially increase head-down time on the flight deck as crews interact with the display. This study examined the feasibility of supplementing Data Comm with synthetic speech in commercial, en-route operations. To this end, 32 air-transport pilots (16 flightcrews) flew two experimental conditions in a Boeing 737-800 fixed-base simulator. In one condition, Data Comm was implemented with a text-only display, and, in the other it was implemented with a text display and synthetic speech that annunciated each message (text+speech). Results indicated that the text+speech display aided the performance of flightcrews compared to text only, without introducing additional complications. Relative to the text-only display, the text+speech display yielded less head-down time. Flightcrews did not delay opening or acknowledging a text+speech message when the party line was active. The majority of pilots reported that the text+speech display was easy to use, helpful, and not distracting; however, this acceptance was attenuated in major-airline pilots. Taken together, these results provide preliminary guidance for aircraft certification regarding the use and implementation of synthetic speech on the flight deck.

Category : Transportation
Languages : en
Pages : 142

Book Description
The 2013 Plan serves as a roadmap of the FAA’s ongoing transition to NextGen and provides an overview of the benefits aircraft operators and passengers are receiving from recent NextGen improvements. NextGen is the shift to smarter, satellite-based and digital technologies and new procedures to make air travel more convenient, predictable and environmentally friendly. Highlights of the Plan include the latest on metroplex initiatives, Performance Based Navigation growth, Automatic Dependent Surveillance-Broadcast deployments, surface collaboration and plans for future benefits. The plan devotes an entire chapter to general aviation and recognizes the growing role of this important stakeholder.

The Effects of Text and Hybrid Graphic-text Formats on Pilot Performance Using Flight Deck Data Communication Displays

The Effects of Text and Hybrid Graphic-text Formats on Pilot Performance Using Flight Deck Data Communication Displays PDF Author: Ricardo Daniel Muñoz Da Costa

Book Description
Air Traffic has shown a steady increase since the institution of commercial aviation in the first quarter of the last century, and the use of the United States National Airspace System (NAS) is expected to increase by 45 percent more passengers by the year 2015 (Smith, 2004). The increasing demands of the NAS require preventive measures in order to preserve the safety of operations. NextGen is a transformative program expected to enhance the safety and effectiveness of NAS operations. One of the ways that it will achieve these goals is by improving air-ground communications. In the current system, communications between pilots and Air Traffic Control (ATC) is accomplished via voice radio; controllers have the task of communicating clearance information to aircraft in their designated airspace. This method of communication proves to be effective when used during urgent situations utilizing short messages. Voice communication can be ineffective and inefficient under various other circumstances. For example, message length and complexity can burden pilot memory. For NextGen, the use of data link allows for the creation of data communication (DataComm) messages and clearances sent directly to flight deck displays, thereby reducing the need for voice. DataComm will enable future communication systems to relieve the pilot from retaining immediate fight path information as it is communicated. This information may overload their cognitive processing abilities resulting in a reduced ability to make accurate and correct decisions. There have been several studies evaluating the effects of DataComm using textual message displays on the flight deck. To date there is no evidence of major research investigation of the use of graphics and or hybrid techniques for DataComm message display. The objectives of this research were to investigate the effects of text and graphics formats on pilot interpretation of spatial clearances given en route. Pilot performance was evaluated for five communication formats (TEXT only, Graphics+Text, Graphics+Text+updated UM, Graphics+Text+Altitude Situation Display, and Graphics+Imbedded Text+Altitude Situation Display). The performance measures were time to interpret an uplink message (UM) from ATC, and percentage of correct responses, including correct acceptance and correct rejection of a clearance. The findings indicated that there are statistically significant differences in pilot performance when using graphics to communicate ATC uplink clearances. As the number of elements in a clearance increased, pilot performance with respect to response time and percent correct was significantly improved with combined graphics and text formats compared to a text-only format.

Publisher: Butterworth-Heinemann
ISBN: 0128006013
Category : Political Science
Languages : en
Pages : 631

Book Description
Practical Airport Operations, Safety, and Emergency Management: Protocols for Today and the Future focuses on the airport itself, not the aircraft, manufacturers, designers, or even the pilots. The book explores the safety of what's been called ‘the most expensive piece of pavement in any city’— the facility that operates, maintains, and ensures the safety of millions of air passengers every year. The book is organized into three helpful sections, each focusing on one of the sectors described in the title. Section One: Airport Safety, explores the airport environment, then delves into safety management systems. Section Two: Airport Operations, continues the conversation on safety management systems before outlining airside and landside operations in depth, while Section Three: Airport Emergency Management, is a careful, detailed exploration of the topic, ending with a chapter on the operational challenges airport operations managers can expect to face in the future. Written by trusted experts in the field, users will find this book to be a vital resource that provides airport operations managers and students with the information, protocols, and strategies they need to meet the unique challenges associated with running an airport. Addresses the four areas of airport management: safety, operations, emergency management, and future challenges together in one book Written by leading professionals in the field with extensive training, teaching, and practical experience in airport operations Includes section on future challenges, including spaceport, unmanned aerial vehicles, and integrated incident command Ancillary materials for readers to reinforce concepts and instructors teaching operations courses Focuses on the topics of safety, operations, emergency management, and what personnel and students studying the topic can expect to face in the future
