Flight Simulator X Prepar3D

This comprehensive AFCAD package refines the layout of Napa County Airport (KAPC) in Napa, California. It includes carefully placed taxiways, aprons, and other critical elements, ensuring a more authentic environment in Microsoft Flight Simulator X. The developers at Clear Sky Simulations used advanced design tools and default scenery components to deliver enhanced realism. The result is a free mod that aviation enthusiasts can install and enjoy without complex setup procedures.

Key Airport Layout Modifications

The updated airport file employs robust techniques in Airport Design Editor (a tool used to modify airfield features) to match actual ground layouts closely. You can expect more accurate parking assignments, appropriately aligned runways, and corrected taxiway connections. Napa County Airport serves general aviation and corporate traffic, so the new spacing accommodates a range of aircraft—from smaller single-engine planes to larger business jets.

Installation Process

Locate the following files in this package: KAPC_CSS.BGL and KAPC_CSS_CVX.BGL.
Transfer both files into the Addon Scenery/Scenery folder of your Flight Simulator X installation.
Start your simulator as usual. Once you load into the Napa region, the enhancements will be active.

Reverting to Default

Open your Addon Scenery/Scenery directory and remove KAPC_CSS.BGL and KAPC_CSS_CVX.BGL.
Reload the simulator and the airport will return to its original configuration.

Scenery Object Visibility

These files rely on default libraries packaged with FSX. To ensure all new objects appear correctly, set your scenery detail sliders to at least a NORMAL level. This adjustment enables higher-resolution textures and displays the various structures and clutter objects that help breathe life into the airport environment.
