Zone

A Zone is a region in the airport which is specialised to performing specific tasks; usually to help passengers board planes or to reduce their needs. There are currently 13 zones in the game, excluding zones that can be created from the planning tool.

Designation
To convert an empty space into a zone, select the desired zone from the zones menu in the user interface and then left click and drag from the first corner that you would like your zone to begin from. Once you are happy with the size of a zone, release the left mouse button and the zone will be created.

Whilst zones initially start off square or rectangular in shape, they can be re-shaped by using the None tool to remove unwanted parts of a zone. Similarly, identical zones that are built next to each other (with no gaps) will be merged into one zone.

Claiming Rooms
Some zones, such as offices, will change their name depending on what member of administrative staff is assigned to the room.

Requirements
Some zones do not function immediately after being constructed, as they may have requirements before they can be used. Before building a zone, the tooltip for that zone will indicate any requirements the room may have.

If a constructed zone does not meet the requirements, the colour of the zone name will become red and warning symbols will appear over the zone. Mousing over the zone will display all unmet requirements and will explain how they can be met.

Costs
It does not cost anything to build a zone. However, some zones have requirements for objects, which do cost money. Similarly, some zones are required to be built indoors - which means that hidden costs of foundations, walls, and floors may have to be paid.
