I’ve completed the first set of beta work for the KTPA I’ve been developing for the Gateway and am posting it here for use. Note that this is very incomplete, and a work in progress. The only thing that I would consider finished is the runway and taxiway layout, including the border taxi lines. The taxiway lines themselves, lights, and signage are incomplete, as are the objects and all of Terminal E. But it’s enough to get started for those who want to give it a shot. NOTE THAT X-PLANE 11.1 IS REQUIRED. The airport WILL NOT work on 10.5 or earlier.
You may download the .ZIP file here. The next step in the release will be to get Terminal E in to basic working order.
