What is the controlling source of temperature information while taxing?

• A. ATIS
• B. OAT
• C. SAT
• D. ISA

Answer: (A)

Temperature information used during taxi is taken from ATIS, the airport’s current weather broadcast. ATIS provides the latest ambient conditions for the field, including the temperature, dew point, wind, and other factors that pilots rely on for planning ground and takeoff performance. This ensures everyone is using the same, officially published value for calculations and decision making while moving on the surface. Outside air temperature is a real measurement from the aircraft’s sensors, but it isn’t the published, authoritative source you reference for ground operations. Static air temperature is a sensor-derived value that isn’t used as the primary source for field weather information. ISA is just a standard reference model, not a live measurement.
