“…Let us now consider the M onte C arlo sim ulation setup that we pressed into the service of validating the fram ework. We have selected seven probabilistic inputs for this exercise, divided into three categories: propulsion, aerodynam ics, and piloting technique [6]. In order to test the influence of all the uncertainty to the designed auto-landing system , the article choose the variables which will have m ajor influence to the auto-landing process and perform ance such as aircraft aerodynam ic error, actuator error, sensors error, initial flight condition and wind disturbance, then we use the M onte C arlo sim ulation to verify that the C AT III auto-landing system can satisfy the practical operational requirem ents [7].…”

Approach/Landing is the phase of most accidents occur to endanger civil aircraft safety. CAT III autoland operation can improve the safety and reliability of aircraft when approach and landing in bad weather conditions, and reduce pilot’s working loads, so CAT III autoland control law design is an important task in advanced flight control system research. However, the most of the related researches are requirement based rather and scenario based. Firstly, the article analyzes the Monte Carlo simulation requirements based on airworthiness requirements of auto-landing system and proposes a Monte Carlo simulation model scheme considering the uncertainty of aircraft dynamic model and the actuator model, the error of sensors and the disturbance of wind, then implements the simulation based on a desktop simulation platform. The simulation result shows that the designed auto-landing system can assure the safe and stable landing of the aircraft on the condition of all kinds of uncertainty, the touchdown point, the vertical landing speed and the attitude are all compliance with the expectation criteria, satisfying the requirement of airworthiness items.
