Abstract:In view of the current lack of temperature compensation capability for the main aircraft models of airlines, there is a lack of low temperature correction methods among air traffic control departments, airports, and flight crews, and there is no temperature markings in other programs except for RNP program. Firstly, this paper explains the main responsibility for low temperature correction, and analyzes the current situation of low temperature correction in China. It was pointed that not all low temperatures need to be corrected, and specific judgments need to be made based on the temperature and flight procedures. Secondly, three methods of low temperature correction were introduced: simple calculation method, ICAO formula method, and table lookup method. It was pointed out that the threshold temperature for low temperature correction can be deduced through the ICAO formula method, and the temperature requiring low temperature correction can be judged through the threshold temperature. Finally, taking Beijing Daxing International Airport as an example, it is concluded that low temperature correction only needs to be considered when both Category II and III instrument landing systems are unavailable and the visibility is at the edge of the chart standard. Except for the above situations, no low temperature correction is needed on the runway at any time.
