Ive done a handful of aircraft repaints in the past, but this is my first excursion into really futzing with FS's innards in any meaningful way.
Doing an overhaul of my local airport, KHWO. FSX's stock dimensions, locations, etc, are all wrong; partially due to the age of the source data they likely used, partially due to just not taking long on this field.
First, stock FSX:
And then, the modified work-in-progress view:
Changes so far include:
A complete overhaul of all four runways, including dimensions, positioning, displaced thresholds, position and type of PAPI lighting, and Ive begun to fiddle with the textures. This is pretty much done.
All taxiways resized (Most are between 35 and 40ft wide in real life, FSX had them all at 70ft

), repositioned, and all taxiway signs updated to match reality. The taxiways are mostly done, signage is not. Also have to update the taxiway assignments, so FS ATC doesnt get hopelessly lost.
Adjusted the southeastern portion of the closed 300ft wide diagonal runway for size and position, and added closed runway markings, and the practice helipad. (Used for autorotation practice.) Still fiddling with this.
Added the BCC/Delta Connection Academy ramp on the NE side of the field, including some of the buildings, and I'm currently using a placeholder static MD-83 to represent the 727-100 that's parked on the west end of the ramp. (Was trucked in for the maintenance school.)
Resized and repositioned the Broward mosquito control ramp on the extreme west side of the field.
Added the non-functional T-hangars to the SE corner. I was considering making them parking, but since most of them are closed/condemned IRL, I decided against it. Also modified/added the Van Wagner hangars to the northeast of the T-hangars.
Adjusted the TBM/Socata ramp at the central south portion of the field, and resized/repositioned the main southern ramp much closer to 9R/27L, as it is in real life. This portion is still very much a work in progress.
Disconnected the Customs and Border Patrol building from the rest of the airport. There is an access road to the end of 27R in reality, but it leads to the CBP parking lot, not aircraft parking spaces as shown in FSX. It's shaped all wrong, as well, and is on the list of things left to do.
Left to do:
Finish the southern main ramp area, including replacing all the parking. Theres a whole mess of tie downs on that ramp, and I hope to provide a more realistic number of parking spaces in FSX, rather than the 9 that appear stock.
Overhaul the northeast diagonal ramp, including buildings and another whole slew of parking. In reality, theres a pair of very busy flight schools on this ramp, along with a rather large maintenance facility. Also need to add another three rows of hangars that are present in reality, north of the existing rows in the sim.
Also need to fiddle with the control tower placement and the surrounding access roads. FSX got close, but its not quite right.
Noob Comments:
I'm not currently planning on any custom modeling or texturing, as it lies far outside of my skillset. Possibly in the future. The BCC building is particularly interesting, and deserves to be modeled.
Those sorts of things will have to wait... FOR VERSION 2.
