Quantitative Analysis of the Impact of Low Temperature on Flight Data

When an aircraft flies in the atmosphere, the variation in environmental temperature can cause significant errors in the flight data. This article analyzes the impact of low temperature on flight data, compares radio altitude and atmospheric altitude in flight data, and verifies the altitude deviation at normal temperature and low temperature. The quantitative comparative analysis of the flight data shows that the atmospheric altitude recorded in flight data at low temperature is slightly higher than that of radio altitude, and the data deviation basically conforms to the current linear relationship of low temperature correction. The research results can provide detailed reference for the altitude changes during aircraft approach stages under extreme weather conditions.
