From Hand Drawing to Digital Visualization: Evolution of Drawing Instruction in Aviation Education

Aviation education has experienced significant transformation in visualization instruction over the past three decades, yet the adoption of digital methods has largely supplemented rather than replaced traditional approaches. As the complexity of today’s avionics systems have grown, it has become much more difficult to conduct effective technical training since many of the older methods of using hand-drawn instructional materials have many limitations. In order to obtain a more thorough understanding of how visualization methods have progressed, their efficacy, and their contextual usage within aviation education, an extensive systematic review of thirty-eight articles published between 1994 and 2025 was conducted. The review follows the PRISMA guidelines to evaluate both the use of hand drawings, digital tools (such as VR/AR and digital twin), and hybrid learning methods. Digital visualization provides a useful way to create knowledge, improve spatial orientation and decrease mistakes while performing maintenance tasks. It is also helpful in pilot and technician training because it helps people make decisions about processes and procedures. While digital visualization is becoming more common in hybrid models of electronic training programs, hand-drawn sketches are still an important part of teaching aerospace engineering because they allow for increased creativity, conceptualization, and fast sharing of ideas. The study also demonstrates how effective visualizations may vary based on the situation; therefore, equal weight should be given to teacher’s intent and learners’ needs along with the resources that are available to create visualizations.
