ISA Temperature and Deviation

Entry Mode:

Ref. Alt. & Temp. ISA Deviation

Reference Altitude:

Altitude must be within ICAO ISA coverage. Select type between geopotential or geometric altitude.

Reference Temperature:

Enter air temperature at reference altitude.

ISA Deviation:

Enter ISA deviation.

Selected Altitude:

Use for calculating temperature at selected altitude. Select type between geopotential or geometric altitude.

Results

ISA Deviation:

▶ ISA Deviation (°C |°F):


ISA Temperature at Reference Altitude:

▶ ISA Temperature (°C |°F):


Temperature at Mean Sea Level:

▶ Temperature (°C |°F):


Temperature at Selected Altitude:

▶ Temperature (°C |°F):


Based on ICAO Doc 7488/3.

According to some regulations, air data computers in aircraft are generally based on geopotential altitude.
