The flight temperature range of civil airliners-USA Aircraft Group Corporation

The flight temperature range of civil airliners includes two parts: the internal temperature of the cabin and the external temperature of the cabin.
First of all, regarding the external temperature of the cabin, civil aircraft generally fly at an altitude of more than 8,000 meters and are located at the bottom of the stratosphere. This
The temperature of the area increases with the increase of height, and the year-round temperature is about minus 56.5°C. When the plane is flying at an altitude of 9,200 meters, the static temperature outside the plane is about minus 45°C. However, considering the aerodynamic heating effect of the aircraft, the total surface temperature of the aircraft is 10 to 25°C higher than the static temperature. In addition, during the flight of the aircraft, the atmospheric temperature will gradually decrease as the altitude increases. When the aircraft reaches a cruising altitude, the atmospheric temperature will usually drop below minus 50 degrees Celsius.
Secondly, regarding the internal temperature of the cabin, the cabin temperature of domestic airlines is generally controlled between 24-27 degrees. When boarding,
The cabin temperature is usually about 25 degrees. After take-off, the cabin temperature may drop slightly, but flight attendants usually adjust the air conditioning temperature.
Make sure that the cabin temperature is maintained within a comfortable range. It should be noted that the actual flight temperature will be affected by a variety of factors, including flight altitude, flight speed, atmospheric conditions, aircraft model and aircraft maintenance. Therefore, the specific flight temperature may be different.
