Which aspect is not generally associated with KLM's aircraft design objectives?

KLM's aircraft design objectives focus on enhancing airline efficiency, safety, and sustainability. Low fuel use and low operating costs are key factors in modern aircraft design, as they contribute to environmental concerns and economic viability. Airlines strive to minimize their carbon footprint and optimize flight operations, making design choices that prioritize fuel efficiency.

Faster aircraft capabilities can also be relevant, as the demand for shorter travel times remains important in the competitive airline market. However, higher atmospheric impact is contrary to these objectives, as increasing the environmental footprint does not align with the industry trend towards reduced emissions and sustainability. Therefore, this aspect is not generally associated with KLM's objectives in aircraft design, as they are committed to minimizing environmental impact while improving operational efficiency.
