What is the standard temperature at sea level?

The standard temperature at sea level is defined as 15 degrees Celsius, which is a key reference point in aviation for understanding various atmospheric parameters. This standard baseline is important for pilots and atmospheric scientists alike, as it serves as a reference for calculating air density, performance metrics for aircraft, and for understanding how temperature influences weather patterns and aircraft operations.

Using this standard temperature, pilots can apply the International Standard Atmosphere (ISA) model, which assumes a decrease of temperature by approximately 2 degrees Celsius for every 1,000 feet of altitude gained. Understanding this concept helps pilots determine altitude corrections for performance calculations, enabling safe operation of the aircraft throughout different flight conditions and altitudes.
