Airworthiness Compliance Criteria in Ergonomic Design of Cursor Control Device for Civil Aircraft

Cursor control device (CCD) has been applied to the integrated avionics system in the cockpit of modern civil aircraft, and gradually becomes one of the main controls in the cockpit. From the perspective of operation frequency and workload, ergonomic design of cursor control device, especially the design of installation location, will become an important aspect of ergonomic airworthiness. Based on anthropometric data and ergonomics combined with biomechanical theory, the control posture requirement of CCD is determined by analyzing the operational situation of CCD, and the reasonable installation location of CCD is calculated by computer aided design technology. From the results of computational analysis and evaluation, there is theoretically a limited installation area, which can meet the needs of most pilots to operate CCD conveniently and efficiently over all flight phases. While satisfying the airworthiness provisions, the relevant theoretical methods and quantitative analysis results can be used as criteria to show the compliance to the authorities.
