Figure 35: Capacity of a pier topology for Gimpo Airport’s expanded parking lot space that complies with the FAA’s new regulations. Figure 36: Capacity of a linear topology for the expanded Gimpo Airport parking lot that complies with the EASA’s new regulations. As a result, if the FAA's new regulations are applied, the most efficient vertiport layout for UAM operation in the Gimpo Airport parking lot is a pier topology consisting of two TLOF pads and 12 gates for the current parking space and the pier topology consisting of three TLOF pads and 11 gates for the expanded parking space. If the EASA's new regulations are applied, the most efficient layouts are the satellite topology consisting of 4 TLOF pads and 18 gates for the current parking space and pier topology consisting of 4 TLOF pads and 20 gates for the expanded parking space.
