What is D-ATIS?
D-ATIS, or Digital Automatic Terminal Information Service, is a system used in aviation to provide pilots with current weather, runway, and other important information about an airport. It is a digital version of the traditional ATIS system, which stands for Automatic Terminal Information Service.
The D-ATIS system works by automatically generating a recorded message that is updated regularly with the latest information about an airport. This message is then broadcast over a designated frequency. For example typically 121.65 MHz, and can be accessed by pilots using their aircraft radios.
Some of the information provided by D-ATIS includes the current weather conditions at the airport, such as wind direction and speed, temperature, and visibility. It also provides information about the active runways, including the runway length, surface type, and any temporary restrictions or closures.
In addition to weather and runway information, D-ATIS can also provide other important information for pilots, such as taxiway closures or construction activity, airspace restrictions, and any other relevant information that may affect flight operations.
D-ATIS is an important tool for pilots, as it allows them to quickly and easily access up-to-date information about the airport they are operating in. This can help them make informed decisions about their flight operations and ensure the safety of their passengers and crew.
