What are the wind and temperature conditions at 12,000 feet MSL as reported by a pilot?

The correct answer indicates that at 12,000 feet MSL, the wind is coming from 080 degrees at a speed of 21 knots, and the temperature is -7 degrees Celsius.

Understanding the wind direction is crucial for flight operations, particularly for takeoff and landing procedures since wind can greatly affect aircraft performance. Wind direction is reported in degrees relative to true north, and it informs the pilot from which direction the wind is coming. In this case, a wind of 080 degrees means the wind is originating from the east-southeast.

Wind speed is presented in knots, which is a standard unit in aviation for measuring wind speed. A speed of 21 knots is a moderate breeze that could influence aircraft performance, especially during takeoff and landing phases.

Temperature at altitude is reported in degrees Celsius, and a temperature of -7 degrees Celsius at 12,000 feet is a typical value for this altitude, as temperatures generally decrease with an increase in altitude in the troposphere.

In a broader context, while all options provide plausible wind and temperature conditions at cruising altitudes, option C is selected because it accurately presents a combination of wind speed, direction, and temperature that aligns with typical meteorological conditions experienced at 12
