8.1. Introduction to ATIS

The Automatic Terminal Information Service (ATIS) provides regular information to aircraft arriving at and departing from an airport, operating continuously for 24 hours or a specified duration. The ATIS is updated on an hourly or 30-minute basis to ensure the information remains current.

ATIS broadcasts normally contain the following information:

• ATIS designator (A, B, C...), changes with ATIS updates
• METAR
• Active runways for departures and arrivals
• NOTAM
• Requests, such as "in the initial contact, report aircraft type and stand number"
