Book excerpt: A simulation in the B747-400 was conducted at NASA Ames Research Center that compared how crews handled voice and data link air traffic control (ATC) messages in a single medium versus a mixed voice and data link ATC environment The interval between ATC messages was also varied to examine the influence of time pressure in voice, data link, and mixed ATC environments. For messages sent via voice, transaction times were lengthened in the mixed media environment for closely spaced messages. The type of environment did not affect data link times. However, messages times were lengthened in both single and mixed-modality environments under time pressure. Closely spaced messages also increased the number of requests for clarification for voice messages in the mixed environment and review menu use for data link messages. Results indicated that when time pressure is introduced, the mix of voice and data link does not necessarily capitalize on the advantages of both media. These findings emphasize the need to develop procedures for managing communication in mixed voice and data link environments.Dunbar, Melisa and McGann, Alison and Mackintosh, Margaret-Anne and Lozito, Sandra and Ashford, Rose (Technical Monitor)Ames Research CenterCOMMUNICATION NETWORKS; VOICE COMMUNICATION; DATA LINKS; AIR TRAFFIC CONTROL; VOICE CONTROL; PRESSURE EFFECTS; MESSAGES; FLIGHT SIMULATION; FLIGHT TEST INSTRUMENTS

This book was released on 2018-06-28 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data link Air Traffic Control (ATC) and Air Traffic Service (ATS) message and data exchange offers the potential benefits of increased flight safety and efficiency by reducing communication errors and allowing more information to be transferred between aircraft and ground facilities. Digital communication also presents an opportunity to relieve the overloading of ATC radio frequencies which hampers message exchange during peak traffic hours in many busy terminal areas. A piloted simulation study to develop pilot factor guidelines and assess potential flight crew benefits and liabilities from using data link ATC message exchange was completed. The data link ATC message exchange concept, implemented on an existing navigation computer Control Display Unit (CDU) required maintaining a voice radio telephone link with an appropriate ATC facility. Flight crew comments, scanning behavior, and measurements of time spent in ATC communication activities for data link ATC message exchange were compared to similar measures for simulated conventional voice radio operations. The results show crew preference for the quieter flight deck environment and a perception of lower communication workload. Waller, Marvin C. and Lohr, Gary W.

Download or read book The Effectiveness of Pilot Response to Genrate Concatenated Downlink Messages After Evaluation of Hybrid Graphic text Clearances written by Steven Brent Kiss and published by . This book was released on 2013 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data-Link Communication, or DataComm, is a digital text messaging system providing a means of communication between Air Traffic Control (ATC) and pilots. Current Pilot/ATC communication is via voice radio, but the number of ATC operators and voice channels are finite, which limits the number of aircraft voice transmission can accommodate. The number of aircraft within the National Airspace System (NAS) is expected to double between 2004 and 2025, and a transition from voice to DataComm is a necessity. DataComm is an integral part of the NAS and is implemented in incremental phases increasing its functions and capability. There are many advantages with DataComm including providing the ability to send a digital message to a specific plane, the ability to send a long and detailed message with accuracy, as well as providing a platform to add additional features after initial implementation. However, DataComm does have critical integration issues into the current avionic systems and flight deck for commercial airliners. In an attempt to limit the number of DataComm transmissions and to support trajectory based operations, future ATC clearances are expected to increase in length and complexity. Pilots will be required to first understand the clearance, and then decide whether it is acceptable. Clearances that are rejected prompt pilots to create a Downlink Message (DM) to ATC to negotiate clearances. Pilots may also initiate a clearance request with ATC. This research focuses on DM creation after pilot evaluation of complex multi-element clearances depicted via text and graphics on a Navigation Display (ND). Two separate touchscreen DM creation interfaces were developed. The research was broken into two separate experiments. All scenarios were presented on a dynamic flight simulator connected to a simulated ATC station. Experiment I was an exploratory study and recorded response time to interpret a clearance, pilot accuracy, and time to create a DM. A Pilot/ATC communication interface (TextGen) was utilized during Experiment I. TextGen was a menu-based system that allowed pilots to create their own DMs by selecting messages from categories on a touchscreen. Graphics of the DM were presented on a ND in correlation to the original ATC clearance as DMs were constructed. Twenty-Four pilots were tested on ten separate concatenated clearances repeated four times each to comprise a total of forty clearances. Half of the clearance scenarios were designed so that the pilot should reject and half were designed to be acceptable. Verbal comments from Experiment I helped formulate recommendations to improve DataComm interfaces for future implementations within the NAS. The results showed that TextGen was time consuming, required excessive input, and demanded 100% of the pilots’ attention during interaction. Experiment II had four separate hypotheses and recorded response time to interpret a clearance, pilot accuracy, and times to create a DM. Experiment II tested two separate Pilot/ATC DM creation communication interfaces. One format was TextGen, (tested in Experiment I), and the second was a direct manipulation graphic interface called AutoGen. AutoGen allowed pilots to create DMs by physically touching graphics that were depicted on a ND. The clearance variables within the DM were automatically altered in correlation with the graphic manipulation. Experiment II compared DM creation time, and response time to interpret a clearance between both presentation formats. Eight separate pilots were tested on both formats. Results indicated that AutoGen allowed pilots to perform more accurately with less time. The average time to create a DM was significantly less when pilots interacted with AutoGen compared to TextGen. Pilots overwhelmingly preferred the AutoGen interface because of the intuitiveness of the display, ease of use, and automation features. The direct graphic manipulation was preferred over the menu-based system. DM graphics, as well as uplink message (UM) graphics, were preferred to text alone by 100% of the pilots tested. This research allowed the development of many human factors recommendations. These recommendations could be used by the Federal Aviation Administration (FAA) to develop standards for future Pilot/ATC DataComm interfaces. One recommendation is to ensure that graphics of DMs on the ND are included when pilots create DMs on DataComm interfaces. Another recommendation would be to allow the option for a hybrid version of menu-based system with direct graphic manipulation. The benefits of both formats could be utilized providing the flexibility to generate any DM from the menu-based system and also utilizing the speed and accuracy of the direct manipulation interface.

Download or read book Misunderstandings in ATC Communication written by Immanuel Barshi and published by Routledge. This book was released on 2016-04-22 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effective radio communication between ATC and pilots has long been recognized as an important element of aviation safety. In recognition of the role miscommunications play in aviation incidents and accidents, the International Civil Aviation Organization (ICAO) recently introduced language proficiency requirements for all flight personnel in all ICAO member states. Using an effective and economical experimental paradigm, the research described here teases apart the complex combination of factors (e.g. speech rate, controller message length, English language proficiency, cognitive workload) believed to contribute to miscommunications between controllers and pilots. Misunderstandings in ATC Communication offers an in-depth report of a seminal study in aviation communication, which until now has only been available in the form of an unpublished dissertation. In addition, it offers a recent extension of that work, the authors’ reflections on the research process, and a thorough review of the aviation communication literature. Graduate students and researchers who wish to address real-world problems will appreciate the simple elegance of the experimental paradigm that has been used to address a wide range of theoretical and applied interdisciplinary research questions. The book will appeal to scholars in the fields of human factors, linguistics, cognitive psychology, applied linguistics and second-language education and assessment. It is also of direct relevance to government and industry decision-makers and operators as they strive to implement the ICAO requirements, and to improve aviation safety.

This book was released on 2003 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Federal Aviation Administration (FAA) Next Generation Air-Ground Communications program plans to replace aging analog radio equipment with the Very High Frequency Digital Link Mode 3 (VDL3) system. VDL3 will implement both digital voice and data link communications and will include special features such as controller override, antiblocking, and a transmit status indicator. There are two human factors concerns with the VDL3 system: voice quality and voice throughput delay. Previous research has determined that digital voice technology is highly intelligible and acceptable for Air Traffic Control (ATC) operations. Researchers from the National Airspace System Human Factors Group (ACB-220) of the FAA William J. Hughes Technical Center conducted a high fidelity, human-in-the-loop simulation to examine the impact of voice throughput delay on ATC operations. The communications equipment simulated the VDL3 system with controller override, antiblocking, and transmit status indicator features. The researchers examined ground system delays of 250 ms (current specification), 350 ms (practical alternative), and 750 ms (to demonstrate the sensitivity of the simulation measures) each with their appropriate airborne system delays. Ten controllers from Level 11 and 12 Air Route Traffic Control Centers participated in the study. The results indicated that there were no significant differences between the 250 ms and 350 ms delay conditions. However, the 750 ms condition did produce a significant increase in controller overrides, and the controllers rated it as interfering with some aspects of their communication (e.g., providing optional services). The researchers concluded that the VDL3 system with controller override, antiblocking, and a transmit status indicator can be implemented with a 350 ms ground system delay without causing problems for controllers.
