The OMC-141-2B Automatic Terminal Information Service (ATIS) is an on-command broadcast of recorded non-control weather information for unmanned offshore oil & gas or offshore wind energy platforms.

The system broadcasts essential weather information, such as air temperature, humidity, barometric pressure (QFH and QNH), visibility, present weather and any other information required by the pilots. Helicopter pilots usually listen to an available ATIS broadcast before the final approach, in order have a safe landing on the platform.

The helicopter pilot can, by using the VHF radio, request the actual weather information (automatic voice message) from the unmanned station. The system also has the possibility to control the helideck lights, by using a standard VHF radio.
