Macros
#define	AIRPORT_GENERIC(name, terminals, num_helipads, flags, delta_z)
	Define a generic airport.
#define	AIRPORT(name, num_helipads, short_strip)    AIRPORT_GENERIC(name, _airport_terminal_ ## name, num_helipads, AirportFTAClass::Flags({AirportFTAClass::Flag::Airplanes, AirportFTAClass::Flag::Helicopters}) | (short_strip ? AirportFTAClass::Flags{AirportFTAClass::Flag::ShortStrip} : AirportFTAClass::Flags{}), 0)
	Define an airport.
#define	HELIPORT(name, num_helipads, delta_z)    AIRPORT_GENERIC(name, nullptr, num_helipads, AirportFTAClass::Flag::Helicopters, delta_z)
	Define a heliport.

Functions
static uint16_t	AirportGetNofElements (const AirportFTAbuildup *apFA)
	Get the number of elements of a source Airport state automata Since it is actually just a big array of AirportFTA types, we only know one element from the other by differing 'position' identifiers.
static void	AirportBuildAutomata (std::vector< AirportFTA > &layout, uint8_t nofelements, const AirportFTAbuildup *apFA)
	Construct the FTA given a description.
AirportMovingData	RotateAirportMovingData (const AirportMovingData *orig, Direction rotation, uint num_tiles_x, uint num_tiles_y)
	Rotate the airport moving data to another rotation.
const AirportFTAClass *	GetAirport (const uint8_t airport_type)
	Get the finite state machine of an airport type.
uint8_t	GetVehiclePosOnBuild (TileIndex hangar_tile)
	Get the vehicle position when an aircraft is build at the given tile.
