Make a new recording of ATIS when...

• A. upon receipt of any new official weather
• B. upon decommission of lasers
• C. when the frequency changes
• D. every hour

Answer: (A)

ATIS should reflect current, time-sensitive information that pilots rely on before taxiing, taking off, or landing. The key trigger for making a new ATIS recording is a change in official weather data. When a new weather observation arrives—such as an updated METAR/TAF that alters winds, visibility, ceiling, or altimeter—the information in the existing ATIS becomes outdated, so a new recording is produced to present the latest conditions. This keeps pilots informed of the actual weather and any effects on runway use or approach procedures.

Other options don’t fit because they don’t represent standard triggers for ATIS updates. A laser decommission doesn’t change the weather or essential operational details included in ATIS. A frequency change is a different kind of operational notice and isn’t the primary reason to re-record ATIS. Updating every hour isn’t required and could lead to unnecessary changes; ATIS is updated when weather or other critical information changes.
