Background Technology

[0002] Low-altitude sightseeing is highly sensitive to weather conditions, especially affected by factors such as turbulence, visibility, temperature, and dust storms. Current technologies lack standardized methods for quantifying turbulence and have not established a unified evaluation system for the meteorological comfort of low-altitude sightseeing, resulting in flight safety assessments relying on experience, difficulty in quantifying the sightseeing experience, and non-standardized operational decisions.

[0003] Therefore, a calculation method that integrates turbulence intensity with comprehensive meteorological comfort is needed to achieve an integrated assessment of safety, experience, and operation. Summary of the Invention

[0005] This invention adopts the following technical solution: a method for calculating the Low Altitude Sightseeing Weather Comfort Index (LCTI) based on EDR turbulence correction, comprising:

[0006] Calculate the turbulence intensity EDR: Based on wind speed, wind shear, airspeed, and flight altitude, perform altitude attenuation correction, wind field contribution calculation, and flight speed calibration to obtain the standardized EDR turbulence intensity.

[0007] Meteorological parameters collected include visibility, cloud base height, temperature, ultraviolet radiation, PM10, solar altitude angle, and relative humidity.

[0008] The LCTI index is constructed using EDR, visibility, cloud base height, temperature, and UV radiation as core indicators, and PM10, solar altitude angle, and relative humidity as correction factors. A comfort score of 0–100 is obtained by weighting the indicators.

[0009] Comfort rating: LCTI is divided into five levels, from I to V, and corresponding flight recommendations are given.

[0010] Weather warnings and dynamic pricing: generate warnings based on weather risk conditions and output pricing strategies based on comfort levels.
