What is the standard temperature for 10,000 feet?

Explanation:
In the standard atmosphere, temperature decreases with altitude at a fixed lapse rate: about 2°C per 1,000 feet from sea level, starting from 15°C at sea level. At 10,000 feet, the drop is 2°C × 10 = 20°C. So the standard temperature is 15°C − 20°C = −5°C. This value is used for performance and instrument calibration under ISA conditions. The other numbers don’t fit the ISA lapse rate for 10,000 feet.
