Update 7/1 - Flightbeam/iBlueYonder has released an update that officially supports toggling of static aircraft! If you disable statics, you can remove my file from the Community folder. It's been a pleasure serving you prior to the officially supported fix. 

Flightbeam's KPDX product includes statics that are not possible to remove by default, which clash with AI traffic models and remove available parking space for users. This mod contains only exclusion polygons and adding parking spots to remove the static aircraft and static jetways bound to the parking spots that were occupied by the AI. 

Removed static aircraft and jetways from gates A (all), B1, C6, C7, C8, C12, C15, C16, D14. Added parking spots and jetways for all except A concourse, as these no longer exist.

You must have the Flightbeam KPDX product in order for this addon to work properly.
