ABSTRACT

Aerodynamic structural alignment represents a cornerstone of aircraft structural integrity, handling stability and flight performance optimization. Among the core parameters requiring rigorous verification during assembly, and routine maintenance operations is the angle of incidence. This review paper presents the design, material selection, fabrication and structural evaluation of a functional working model of an aviation incidence board developed by us at the Pune Institute of Aviation Technology. An incidence board serves as a specialized mechanical checking device that measures the specific fixed angle of a wing's chord line relative to the aircraft's longitudinal axis. The functional model incorporates a stable structural board, localized positioning stops, an adjustable verification scale and a spirit bubble fluid level mechanism to demonstrate high accuracy angular readings. By analyzing the structural mechanics of the tool alongside the engineering and budgetary constraints involved, this study bridges the gap between theoretical aerodynamics and practical aircraft maintenance engineering training. Additionally, the paper provides a complete roadmap of the work distribution matrix, absolute budgetary structures, operational algorithms and outlines a comprehensive future scope.
