Which of the following is NOT a purpose of shelter orientation?

Shelter orientation is an important aspect in various fields, particularly in architecture, urban planning, and environmental science, focusing on the placement and alignment of structures to maximize their efficiency and comfort in relation to environmental factors. The primary purposes of shelter orientation typically include reducing shadow, minimizing solar radiation exposure, and mitigating wind effects.

Reducing shadow is crucial for ensuring that sunlight penetrates the interior of a building or structure, which can enhance natural lighting and reduce reliance on artificial lighting. Reducing solar radiation aims to protect the occupants and interior finishes from excessive heat and glare, thereby improving indoor comfort and reducing energy consumption for cooling. Additionally, minimizing wind effects is vital for improving shelter stability, comfort, and energy efficiency, potentially influencing heating and cooling needs.

The option that does not align with these objectives is related to facilitating aircraft maintenance. While aircraft maintenance is important, it is not a purpose associated with the orientation of a shelter. The orientation of shelters is primarily concerned with environmental factors impacting comfort and efficiency, rather than the practicalities of aircraft upkeep. Hence, this is why the correct answer is identified as the one referring to aircraft maintenance.
