What is the standard sea level temperature using standard atmospheric conditions?

The standard sea level temperature under standard atmospheric conditions is 59 degrees Fahrenheit (15 degrees Celsius). This temperature is part of the International Standard Atmosphere (ISA) model, which is widely used in aviation and meteorology. The ISA provides a reference for temperature, pressure, density, and other atmospheric properties, allowing for consistent calculations and comparisons.

At sea level, the ISA assumes a temperature of 15 degrees Celsius as a baseline. This value is essential for various calculations, including those related to aircraft performance, engine efficiency, and navigation. Understanding this standard temperature helps pilots and engineers to correctly assess the performance of aircraft engines under different atmospheric conditions, ensuring safe and efficient operations.
