How Cross Cutting Issues are Addressed in the Course
The Aircraft Structure I course focuses on the technical principles of aircraft structural design, including material
selection, load distribution, and stress analysis. While the course is primarily technical, it indirectly addresses
Emerging and Demographic Changes through the design of adaptable and inclusive structural solutions. This
aligns with:
● PO3 (Design/Development of Solutions): Designing adaptable structures for evolving aviation needs.
● PO6 (The Engineer and Society): Considering demographic shifts like aging populations and urban air
mobility.
Other cross-cutting issues, such as ethics, sustainability, and environmental concerns, are not explicitly covered
in this course.
11. 11
All Needs Categories Mapping
The Aircraft Structure I course provides specialized knowledge in aircraft structural design,
including material selection, stress analysis, and load distribution. While the course content is
highly technical, it aligns with regional needs by addressing the demand for locally relevant
aircraft materials and structural designs that cater to specific environmental and operational
conditions. This focus on regional adaptability ensures the course content supports the
development of aircraft suited to regional aviation needs, such as regional air travel and the use
of locally sourced materials. Therefore, the course implicitly contributes to regional development
but does not explicitly map its objectives to broader local, national, or global needs as per AICTE
categorization.
