What is the standard temperature at an altitude of 10,000 feet?

• A. -5 degrees C
• B. -10 degrees C
• C. 0 degrees C
• D. -15 degrees C

Answer: (A)

At an altitude of 10,000 feet, the standard temperature is typically around -5 degrees Celsius. This value is derived from the International Standard Atmosphere (ISA) model, which establishes a baseline for temperature at various altitudes. According to the ISA, the temperature decreases with altitude at a lapse rate of approximately 6.5 degrees Celsius per kilometer up to a certain point in the atmosphere. At sea level, the standard temperature is about 15 degrees Celsius. As one ascends to 10,000 feet, which is roughly 3,048 meters, the temperature would be adjusted downward according to the lapse rate. Thus, taking into consideration the temperature drop, we find that at 10,000 feet, a standard temperature of -5 degrees Celsius accurately reflects this decrease. Understanding this standard is crucial for aircraft performance calculations and ensuring safe operating conditions in lighter-than-air operations.
