Factors Affecting Training Effectiveness and Their Relationship with Aviation Safety : (An) Empirical Case Study in Yemen Global Aviation Policy

다국어 초록 (Multilingual Abstract)

Aviation safety is influenced not only by regulatory and technological systems but also by the quality and effectiveness of human-centered training programs. This study empirically investigates how training curriculum design (TC), instructor characteristics (IS), and the training environment (TE) influence training effectiveness (TEF) and, subsequently, aviation safety (AS) within Yemen’s civil aviation sector. Guided by Baldwin and Ford’s (1988) Transfer of Training Model and ICAO’s Competency-Based Training and Assessment (CBTA) framework, the study examines both the direct and mediated pathways linking training quality to safety performance. A quantitative, correlational, cross-sectional design was implemented using a structured questionnaire administered to aviation personnel from CAMA, Yemenia Airlines, and major airports. A total of 179 valid responses were analyzed using Structural Equation Modeling (SEM) with 5,000 bootstrap resamples. Reliability and validity assessments confirmed strong internal consistency (Cronbach’s α > 0.88) and acceptable psychometric properties. The SEM results showed that TC, IS, and TE significantly predict TEF (β = 0.270, 0.457, and 0.171, respectively). TEF, in turn, demonstrated the strongest direct effect on AS (β = 0.556). TC and IS exhibited significant direct effects on AS (β = 0.239 and 0.143), whereas TE had no significant direct effect (β = 0.0747, p = 0.143). However, all three predictors exerted significant indirect effects on AS through TEF (TC = 0.158; IS = 0.243; TE = 0.0871), confirming training effectiveness as the central mediating mechanism. The model explained 66.9% of the variance in TEF and 85.8% in AS, demonstrating strong predictive power. The findings conclude that enhancing curriculum structure, strengthening instructor competence, and improving training environments can substantially elevate aviation safety through improved training effectiveness and learning transfer. This study extends Baldwin and Ford’s model to a developing-country aviation context and provides evidence that effective training is a strategic driver of operational safety and organizational resilience.
