Designing Vertiport Access in Controlled Airspace: Class C
One of the more complex challenges in Advanced Air Mobility is how vertiports will integrate into controlled airspace, especially in Class C environments where conventional traffic, sequencing, and communications are tightly managed.
Many conventional instrument procedures may not align well with the performance profiles and operational needs of eVTOL aircraft. A typical ILS approach might be 10–12 miles long, eating up 10 to 15 minutes of flight time. When your total electric range is just 100 miles, that’s a significant operational cost.
Instead, emerging approaches are being designed around the unique capabilities of eVTOLs steeper descent profiles (typically 4–6°, with some experimental cases reaching 7–9°) and much shorter approach paths, often just 3 to 4 miles in length. These procedures allow for more compact, urban friendly arrival corridors.
It raises the bigger question: If you were designing airspace from the ground up, how would you structure it to support eVTOL corridors and short, steep approaches?
