I am trying to add my first simple airport on the island of Tenerife, which is a no-DLC zone as you know (maybe it's the problem?). I created the TSC file and it will actually show correctly in the "Location" map of the game, but when firing up the sim, the runway will not show as you can see on the attached screenshot. Oddly, the PAPI is there!
I also tried putting the "runway.tmb" file I found in the Hawaii user-contributed DLC (sorry, just testing!) but no luck either.
Here is the TSC file :
Any wisdom would be much appreciated, thanks!
