Pilot-controller communication is critical to safe and efficient flight. It is often a challenging component of piloting, which is reflected in the number of incidents and accidents involving miscommunication. Our previous field study identified communication problems that disrupt routine communication between pilots and controllers. The present part-task simulation study followed up the field results with a more controlled investigation of communication problems. Pilots flew a simulation in which they were frequently vectored by Air Traffic Control (ATC), requiring intensive communication with the controller. While flying, pilots also performed a secondary visual monitoring task. We examined the influence of message length (one message with four commands vs. two messages with two commands each) and noncommunication workload on communication accuracy and length. Longer ATC messages appeared to overload pilot working memory, resulting in more incorrect or partial readbacks, as well as more requests to repeat the message. The timing between the two short messages also influenced communication. The second message interfered with memory for or response to the first short message when it was delivered too soon after the first message. Performing the secondary monitoring task did not influence communication. Instead, communication reduced monitoring accuracy. Morrow, Daniel and Rodvold, Michelle Unspecified Center NAS2-13210...

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in-depth report of a seminal study in aviation communication, which until now has only been available in the form of an unpublished dissertation.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.

The influence of Air Traffic Control (ATC) instruction format (grouped vs. sequential presentation) and message length on General Aviation pilot communication was investigated in a simulated flight environment using the Civil Aeromedical Institute's (CAMI's) Basic General Aviation Research Simulator (BGARS). Prior to flying the simulator each pilot was provided with familiarization training, listened to and read back ATC messages spoken in either grouped or sequential format (depending on their assigned treatment group), and completed a digit span test (a measure of short-term memory). While flying 2 missions in the simulator, 12 pilots heard recorded ATC messages that contained altitude and radio frequency information spoken in a grouped format (e.g., "descend and maintain forty-one hundred"), and 12 heard the same instructions spoken sequentially (e.g., "descend and maintain four thousand one hundred"). The amount of information in a message varied from 2 to 5 speech acts, including the aircraft identification. All pilots were instructed to read back and execute the ATC instructions. Readback errors and requests to clarify ATC messages were the primary measures of pilot communication. Readback strategies, such as whether pilots repeated instructions in the same format as issued by ATC, were also examined. We found only limited evidence that the grouped format improved pilot memory for ATC messages. In one analysis of requests for clarification, pilots who received grouped instructions produced fewer requests than did pilots who received the same instructions in sequential format, suggesting that they were less likely to misunderstand the ATC messages. Pilots who received grouped instructions were also more likely to read back the grouped instructions in sequential format, suggesting that prior experience with the sequential format influenced pilot communication in this study.

"Field data and laboratory studies conducted in the 1990s reported the rate of pilot readback errors and communication problems increased as controller transmissions became more complex. This resulted in the recommendation that controllers send shorter messages to reduce the memory load imposed on pilots by complex messages. More than 10 yrs have passed since a comprehensive analysis quantified the types and frequency of readback errors and communication problems that occurred in the en route operational environment. Hence, a content analysis was performed on 51 hrs of pilot and controller messages that were transmitted from five en route facilities in the contiguous United States between March and August 2006. This report contains detailed and comprehensive descriptions of routine air traffic control (ATC) transmissions and how ATC message complexity and message length affected pilot readback performance. The results show that message complexity had a statistically significant effect on the production of errors of omission only, while message length affected both the production of errors of omission and readback errors (substitution and transposition errors)."--Page i.

Field data and laboratory studies conducted in the 1990s reported that the rate of pilot readback errors and communication problems increased as controller transmissions became more complex. This resulted in the recommendation that controllers send shorter messages to reduce the memory load imposed on pilots by complex messages. More than 10 years have passed since a comprehensive analysis quantified the types and frequency of readback errors and communication problems that occur in the operational environment. Hence, a content analysis was performed on 50 hours of pilot and controller messages that were transmitted from 5 of the busiest terminal radar approach control facilities in the contiguous United States between October 2003 and February 2004. This report contains detailed and comprehensive descriptions of routine air traffic control (ATC) communication, pilot readback performance, call sign usage, miscommunications, and the effects of ATC message complexity and message length on pilot readback performance. Of importance was the finding that both the number of pilot requests and readback errors increased as the complexity and number of aviation topics in ATC messages increased - especially when pilots were performing approach tasks as compared with departure tasks. Also, nonstandard phraseology associated with a lack of English language proficiency and international communications were present in the data. In particular, pilot use of the word "point" as part of a radio frequency was included in the read back of altitude ("three point five") and speed ("two point seven on the speed"). To limit the occurrence of communication problems and misunderstandings, controllers should be encouraged to transmit shorter and less complex messages. With increases in international travel, areas of concern related to English language proficiency and language production need to be addressed.

This book offers an HPSG-based discourse grammar for a controlled language (Air Traffic Control) that allows the identification of well-formed discourse patterns. A formalisation of discourse theoretical structures that occur especially in crisis situations that involve potential aviation disasters is introduced. Of particular importance in this context are discourse sequences that help secure uptake among the crew and between crew and tower in order to coordinate actions that might result in avoiding a potential disaster. In order to describe the relevant phenomena, an extended HPSG formalism is used. The extension concerns the capability of modelling speech acts as proposed by Searle & Vanderveken (1985). The grammar is modelled by employing XML as a denotational semantics and is applied to the corpus data. This work thus lays the foundation for the automatic recognition of discourse structures in aviation communication.
