APi's: ¿What are they, where they go?

[Jean Loup]

In some aircraft packs from Linn & Bill, with fligts, scenery & lots of extras, has this strange APi's shaped like a LEGO brick. I wonder ¿where do they fit? So far NOT using them, ¿what am I missing? (in FS 2004)

These are API macros. http://simviation.com/1/browse-Scenery+Design+Objects-100-14

They're scenery objects used with the older scenery design software like Airport 210 & FSSC, mainly for FS98/2000.

The API file extension is also used by an Adobe Acrobat Plug-in which explains the icon in your shot. http://whatis.techtarget.com/fileformat/API-Adobe-Acrobat-plugin-file
This is not the first time that Adobe has used MSFS file extensions.

Better late than ever... I appologize: I found a MACRO SECTiON in my "Golden Wings 3" files, do not know how that works or if it is for FS 2000/FS 98 to also transform into Golden Wings.

¡¡GRACiAS & HASTA LA ViSTA!!

I downloaded the Waco in your shot to check it out. This is copied from the instructions in ReadWaco.txt.

MODIFICATIONS:
There is included in the package an API file so that you can use one of the many excellent freeware scenery programs to place your hangar or additional hangars wherever you desire. You can expand your flying service to include many scenic locations! If you desire to change your aircraft registration number just select the aircraft and change it as you would the default MS aircraft. The waco custom plate on the instrument panel can be customized with your name using any paint program. Make sure you use 8 bit 256 colors. Also the hangar sign can be similiarly changed if you want a new name for your service. If you have a face-on photo of yourself you can make a 256x256x256 bitmap to replace the pilot.bmp in the texture folders and you will find yourself in the Waco cockpit!!
