This is a simple scenery which puts four buoys in the waters near the Gibraltar airport as a visual add for pilots the help them lineup with the runway, one in the bay for runway 9 and three in the mediterranean sea for runway 27.
There are two versions. The folder LXGB-Gibraltar_buoys only has the four buoys. The folder LXGB-Gibraltar_buoys_Exclude has the four buoys and a exclude to removes the Gibraltar cablecar from Mamu82's projectlifts in case you have the RDprojects LXGB scenery which has it's own cablecar.
For it to work the folder Buoys_Gibraltar_Exclude has to be higher in the alphabetic order than the projectlifts folder.
Just put the folder LXGB-Gibraltar_buoys or the folder LXGB-Gibraltar_buoys_Exclude in your community folder. To remove just delete the folder.
