Airport reference temperature

The airport reference temperature is the maximum temperature a pilot usually has to expect at an airport. Together with the airport height , the maximum density height to be expected can be calculated, apart from extreme values. This value can be useful in the early stages of flight planning.

The ICAO stipulates that an aerodrome reference temperature must be determined in degrees Celsius for each airport . This must be published in the AIP .

The ICAO recommends calculating the airport reference temperature using the following method: The airport reference temperature should be the monthly mean of the daily maximum temperatures for the hottest month of the year (the hottest month is the one with the highest monthly mean temperature). This temperature should be averaged over a period of several years. However, this calculation method is only a recommendation, so the individual countries may also use other methods.
