The ATIS broadcast contains critical information for every departure and arrival. Here’s what to listen for and why each element matters.
Information Identifier
Each ATIS broadcast has a phonetic letter identifier (Alpha, Bravo, Charlie, etc.). This identifier changes when the information changes. Tell ATC which ATIS you have—it confirms you’re working with current information.
Weather Elements
The core weather data includes:
- Wind: Direction and speed in knots. Variable winds noted.
- Visibility: Statute miles. Less than 3 miles is significant.
- Ceiling: Cloud height above ground. Broken or overcast matters for VFR.
- Temperature/Dewpoint: When close together, expect fog or low clouds.
- Altimeter: Essential for accurate altitude indication.
Runway Information
Listen for the active runway and approaches in use. This tells you what to expect for sequencing and helps you plan your arrival or departure path.
NOTAMs and Remarks
Closed taxiways, construction, temporary restrictions, and other special conditions appear here. Miss this and you might taxi into a closed area or be surprised by restrictions.
The Readback
When contacting tower or ground, include the ATIS identifier: “…with information Charlie.” This saves time and confirms both parties are using current data.
Write down key items before calling. ATIS comes fast—having it on paper prevents missed information and ensures you’re prepared for operations.
