Safety Evaluation of A380 Wake Turbulence Separation

Abstract

CAAC (Civil Aviation Administration of China) set a standard on A380 wake turbulence separation right after China Southern Airlines brought in Airbus A380 in 2001.This paper considers from the possibility of the latter aircraft wake turbulence influencing the preceding one, which means the wake turbulence risk, makes safety evaluation on the wake turbulence separation standard of the preceding aircraft as A380, and the latter one as heavy type, medium type and light type, based on the safety target level that ICAO (International Civil Aviation Organization) authorized. Each type chooses a typical aircraft to calculate the possibility of influenced by the preceding wake turbulence corresponding with the standard under calm wind. The final result shows that the A380 wake turbulence separation standard setting by CAAC is safe.
