Which combination of weather information sources is commonly used in airfield operations?

• A. METARs, TAFs, ATIS
• B. METARs and NOTAMs
• C. METARs, TAFs, ATIS, and NOTAMs related to weather
• D. METARs only

Answer: (C)

In airfield operations, having a complete picture of weather conditions is essential for safe planning and decision-making. METARs provide real-time weather observations for the airport—wind, visibility, weather phenomena, sky condition, temperature, dew point, and altimeter. TAFs offer forecasted weather for the next several hours, helping crews anticipate changes that could affect takeoffs, landings, and routing. ATIS delivers continuous, broadcasted airport information, including current weather, active runways, and other operational advisories that crews need before taxi and departure. Weather-related NOTAMs communicate temporary or upcoming weather-driven restrictions or hazards, such as runway closures, outages, or severe weather advisories that could impact operations. Combining METARs, TAFs, ATIS, and NOTAMs related to weather gives the most thorough and timely picture, covering current conditions, near-term expectations, ongoing operational notes, and any notices about weather-related changes. This full set is needed because each source fills a different gap: METARs are the present snapshot, TAFs project forward, ATIS consolidates essential airport information for现场 operations, and NOTAMs alert you to changes or risks that could alter playbooks or procedures. Not having any one of these can leave gaps in awareness and increase risk during planning and execution.
