Plenty of them! Scenery developers tend to model their local airfields first and, as a result, there are many full-modeled airports suitable for GA operations.
I was specialized in GA airports in west Spain, and I modeled many them after a visit in real life, sometimes using real photos. La Cerdanya, La Seu and Alfés are are some of "my" GA airports, and I've landed a hundred times in them both in real life and FG:
- LECD La Cerdanya, easily my favourite airport in real life. In the middle of the Pyrenees, next to the France-Spain border. GA, ULM and gliders. Check the "trinxat" in its restaurant!
Real life:
FG:
- LESU Andorra-La Seu, on the top of a mountain next to the Andorra-Spain border. If you go out of the runway, you'll fall down the cliff! GA and ULM, but is is prepared to host commercial flights.

FG:
- LEAT Alfés, in the middle of the "Lleida plains". After 80 years of service, it was closed 5 years ago but it is still serviceable in FlightGear. Dirt runway, a bit tricky to see from above but it has a NDB station nearby. Buildings use real textures from photos taken by me. I participated in a precision landing competition here 10 years ago and I got the last position. Check the "escargots" in the restaurant!

The trip LEAT-LESU-LECD is about 45 minutesr and I believe it is a nice trip to practice some VFR navigation:
https://skyvector.com/?ll=42.0091012573 ... 223N00151EThe trip LESU-LECD is about 15 minutes and I think it is a nice trip to know the area.
I developed other specifically GA airports all around Spain: LERE Requena, LE01 Avinyonet, LECN Pinar de Castellón, LESL Menorca, LESB Majorca, LEBA Malaga, LECO Cordoba, LECI Jaca... and some others you'll need their GPS coordinates to get there! Also, nearly all developed airports in Spain (Barcelona and Madrid being the obvious exceptions) not only accept GA operations, but they are probably their main activity: LERS Reus, LEDA Lleida, LEHC Huesca, LEPP Pamplona, LEGE Girona, LESA Salamanca, LEBG Burgos, LELN Leon, LEVD Valladolid...
Notice: LERS-Reus was my home airport and all GA airports about 2 hour from there are reasonably well developed.
Check
http://iveze.nl/fgmap/. It is probably outdated, but it includes many airports all around the world with at least one custom building. This map was automatically built and the airport is classified according to the runway length, I guess. Orange and red marks are GA airports. The orange marks are actually "GA airports big enough to receive a turboprop"
