Copy this folder to your "Addon Scenery" folder and assign it to a scenery layer within Flight Simulator's scenery settings screen. If you have a previous Abu Dhabi scenery you can replace it with this one, BUT REMEMBER TO REMOVE ANY DUPLICATE AFCADS.

The AFCAD files for this scenery are kept with the scenery itself, there are three. OMAA, OMAD and OMA1 (which the helicopters use).
