| Abstract | In this study, an integrated approach based on MRQ (Multiple Resources Questionnaire), NASA-TLX (NASA-task load index), SWAT (Subjective Workload Assessment Technique) and VACP (visual, auditory, cognitive, psychomotor) model was applied to the subjective measurement workloads of 22 commercial aviation pilots, which aviated the Airbus A320 in the approach phase in two scenarios-ILS CAT I (clear-air turbulence I) and CAVOK (ceiling and visibility OK). Three subjective scales were used to evaluate the pilot workload from different levels of flight tasks. (1) Modified NASA-TLX was used to measure total workload in the approach phase; (2) SWAT was used to measure the workload of 11 subtasks in the approach phase; (3) The newly designed BCMS (Behavior-Cognitive Model Scale) based on VACP model and MRQ by this study was used to measure specific resources in each subtask. Results in this study suggested that NASA-TLX factor structure should be modified, which is not suitable for highly automation in commercial aviation. The reasons why resources occupied cause higher workload in information processing procedure are found by comparing results of VACP model used to pre-test and SWAT used to post-test, which can be taken as reference to improve the design and training programs to some extent. BCMS was used to analyze pilot mental resources which have a high correlation between the total workload in each subtask and improve diagnosticity and reduce implementation difficulty. There were significant differences in some perceptive and cognitive resources among three typical pilots. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
