The Automatic Terminal Information Service (ATIS) is a continuously broadcast recorded message that provides pilots with essential airport and weather information. ATIS is designed to reduce radio congestion by delivering routine data without requiring direct pilot–controller communication.
Pilots are expected to listen to ATIS before contacting ATC, then report the current ATIS identifier (letter or number) on first contact.
Information typically included in ATIS
- Airport identification
- ATIS code (letter or number, e.g. “Information Alpha”)
- Time of observation (usually in Zulu time)
- Wind direction and speed
- Visibility
- Weather phenomena (rain, fog, storms, etc.)
- Cloud coverage and ceiling
- Temperature and dew point
- Altimeter setting (QNH / inches of mercury)
- Active runways
- Approach types in use
- NOTAMs or special remarks (runway closures, braking action, bird activity)
Purpose of ATIS
- Reduces repetitive radio transmissions
- Standardizes pre-arrival and pre-departure information
- Improves situational awareness before ATC contact
- Speeds up clearance and approach coordination
Operational usage
- Before departure:
Pilots obtain ATIS to confirm active runway, weather, and altimeter before requesting clearance or taxi. - Before arrival:
Pilots listen to ATIS to prepare for the expected runway, approach type, and weather conditions.
On first contact with ATC, pilots typically state:
“With information Alpha.”
Application in DCS World
- DCS airbases provide simplified ATIS-style broadcasts, usually accessible via the radio menu.
- Information typically includes:
- Active runway
- Wind
- QNH
- Full real-world detail (cloud layers, NOTAMs, trends) is not modeled.
- ATIS identifiers (Alpha, Bravo, etc.) are generally not simulated.
In multiplayer, human ATC controllers or scripted servers may simulate more realistic ATIS procedures, especially when used alongside SRS or LotATC.
Training focus
Cadets should:
- Tune ATIS before contacting ATC
- Cross-check wind and QNH against cockpit instruments
- Anticipate runway and approach changes
- Treat ATIS as pre-flight and pre-arrival discipline, not background noise
