ICAO SARPS state that Air Traffic Services are required to provide flight information. Despite it not being the most accurate and efficient method, it is often the Air Traffic Controller that assumes responsibility for broadcasting this information. Although several new techniques are being developed, suitable tools and techniques are not always available to the controller.

The workload implied to meet all the ICAO requirements about the passing of information, which can include a lot more than just SIGMET and AIRMET information may be considerable. It can be difficult to determine if pilots have received up to date flight information.
