Indicated altitude is defined as?

Indicated altitude refers to the altitude that is displayed by an altimeter without any adjustments for factors such as temperature or pressure deviations from standard atmospheric conditions. This means the reading shown on the instrument reflects the uncorrected altitude based solely on the current atmospheric pressure setting.

In aviation and meteorology, understanding indicated altitude is important because it helps pilots make initial assessments of their altitude relative to their flight parameters, even though this may not represent the true altitude above mean sea level or take other factors like temperature corrections into account. The indicated altitude is simply the initial reading that a pilot observes, which may require further interpretation or correction to fly safely and accurately.
