eVTOL Infrastructure Considerations for Advanced Air Mobility

  • Providing the latest information and data for vertiport & heliport design considerations
  • Differentiating aviation reality from marketing hype and animated fiction
  • All students will receive an AIAA Certificate of Completion at the end of the course


The eVTOL industry is moving at a rapid pace with numerous aircraft currently in the process of certification. While some see the first eVTOL aircraft being potentially certified within the next two to three years, these unique modes of transportation will still need a suitable and safe place to take off and land. This course will provide a basic understanding of what vertical lift infrastructure is and what key elements need to be considered as well as provide an overview of some of the more technical aspects that must be considered.


  • Identify commonly used terminology for defining and describing infrastructure.
  • Calculate infrastructure dimensions necessary to support vertical lift operations. 
  • Understand the basics of airspace design to support vertical lift infrastructure.
  • Gain an up-to-date understanding of the latest developments in infrastructure standards
  • .Identify aircraft performance criteria to consider for infrastructure design.
  • Understand the influence urban environments have on infrastructure design and safety.
  • Review factors shown to perpetuate infrastructure accidents.
  • [See detailed course outline below]
This course is designed for those interested in learning what it will take to develop eVTOL and powered lift infrastructure that is feasible, economical, and safe, that is accessible to all, and that is assured longevity. Participants will be provided the key building blocks of vertical lift infrastructure design, development and safety in conjunction with an emphasis on strategic aspects specific to complexed urban environments. As such, this course has been developed for both individuals who have little experience in vertical lift infrastructure as well as those who may have a significant level of knowledge on the subject.
This course is also available on-demand. (Sign-In To Register)
