|. International Standard Atmosphere (ISA) is a model used for the standardization of aircraft instruments. It was established, with tables of values over a range of altitudes, to provide a common reference for temperature and pressure. Flying in ISA-plus temperatures will have a negative impact on aircraft performance.
During those same years, the most commonly used standard reference conditions for people using the Imperial or customary USA system of units was 60 Â°F (520 Â°R) and 14.696 psia (i.e., 1 atmosphere of absolute pressure) because it was almost universally used by the oil and gas industries worldwide.
