Microwave ILS Scanning Beam Data Rate Analysis Applied to the CH-53A Helicopter.
Abstract
Data rate requirements for low visibility approach with a sample data measurement of glidslope deviation was investigated analytically using CH-53A helicopter dynamics. A 'window' was 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 was defined as the probability of missing the window, which corresponds to the probability of a missed approach. The landing approach process was 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 was modeled by a state estimator and a state feedback matrix which was optimized so as to minimize the probability of a missed approach subject to rms constraints on control activity.
