Which of these assessments is NOT mentioned as part of site selection considerations?

The assessment that is not mentioned as part of site selection considerations is the environmental impact assessment. Site selection involves various evaluations specific to the operational and technical requirements of a location, such as assessing its physical characteristics and suitability for the intended purpose.

Pavement evaluation, airfield suitability assessment, and landing and drop zone assessment are directly related to the infrastructure, usability, and operational effectiveness of a site for airfield purposes. These assessments focus on ensuring that the physical environment can support necessary activities, such as logistics operations and aircraft operations. On the other hand, while environmental impact assessments are crucial in many planning scenarios, they may not be specifically highlighted in the context of site selection for airfields or operational sites in this particular framework. Thus, option B stands out as not being included in the essential criteria for the mentioned site selection considerations.
