Analysis of Data Rate Requirements for Low Visibility Approach with a Scanning Beam Landing Guidance System.
Abstract
Data rate requirements for low visibility approach with a sample data measurement of glideslope deviation are investigated analytically. A 'window' is defined by specifying certain allowable deviations in the aircraft motion variables which are acceptable for continuation of the landing at a 100-ft-decision altitude. The approach performance is defined as the probability of missing the window, which corresponds to the probability of a missed approach. The landing approach process is modeled by a system of stochastic differential equations, which account for the aircraft dynamics, atmospheric disturbances, guidance errors, and data rate. The flight control system is modeled by a state estimator and a state feedback matrix which is optimized so as to minimize the probability of a missed approach subject to rms constraints on control activity.
