◆ GetAirportNumHelipads()

static int AIAirport::GetAirportNumHelipads ( AirportType type )

static

Get the number of helipads of this airport type.

Parameters

type	The airport type.

Precondition: IsAirportInformationAvailable(type)

Returns: Number of helipads of this type of airport. When 0 helicopters will go to normal terminals.

◆ GetAirportType()

static AirportType AIAirport::GetAirportType ( TileIndex tile )

static

Get the AirportType of an existing airport.

Parameters

tile	Any tile of the airport.

Precondition: AITile::IsStationTile(tile).; AIStation::HasStationType(AIStation.GetStationID(tile), AIStation::STATION_AIRPORT).
