What are the standard temperature and pressure values at sea level?

15ºC and 29.92" Hg
20ºC and 29.92" Hg
15ºC and 30.00" Hg
10ºC and 29.85" Hg

The correct answer is: 15ºC and 29.92" Hg

At sea level, the standard temperature is defined as 15ºC, and the standard pressure is set at 29.92 inches of mercury (Hg). These values come from the International Standard Atmosphere (ISA), which provides a uniform reference for atmospheric conditions used in aviation and meteorology. The standard temperature is important for understanding aircraft performance, since it influences lift and engine efficiency. The pressure value is critical as well, affecting altimeter settings, which indicate altitude based on atmospheric pressure. When pilots and meteorologists refer to "standard conditions," they are usually referencing these specific values, which help ensure consistency in communication and calculations across various sectors of aviation.
