Which of the following is NOT a focus area for AAM according to the text?

The focus areas for Advanced Air Mobility (AAM) are geared towards innovation and advancement in the aviation sector that address modern challenges and opportunities. Environmental sustainability, market competitiveness, and cost-saving technologies are all critical components of AAM initiatives. These areas concentrate on developing aircraft and systems that are not only efficient but also able to minimize their impact on the environment, remain competitive in a growing market, and reduce operational costs through new technologies.

In contrast, historical aviation practices do not align with the innovative goals of AAM, as they pertain to traditional methods and systems that have been established in the aviation industry over many years. AAM represents a forward-looking approach that seeks to evolve beyond conventional practices, focusing instead on emerging technologies and sustainability. Thus, historical aviation practices are not a focus area for AAM.
