Tracking of Nonstationary Noise Based on Data-Driven Recursive Noise Power Estimation

This paper considers estimation of the noise spectral variance from speech signals contaminated by highly nonstationary noise sources. The method can accurately track fast changes in noise power level (up to about 10 dB/s). In each time frame, for each frequency bin, the noise variance estimate is updated recursively with the minimum mean-square...

Flight simulator evaluation of advanced MLS procedures

The flight simulator study described in this report concerns an evaluation of manually flown, flight director aided, curved MLS approach and departure procedures with a simulated wide-body transport aircraft. Four curved approach paths and two departure procedures have been evaluated, where these procedures were determined to be beneficial from...

Flight simulator evaluation of the flyability of curved MLS approaches with wide-body aircraft

The flight simulator study described In this report concerns an evaluation of flight director flown curved MLS approach paths with a simulated wide-body transport aircraft. Four curved approach paths, consisting of two straight segments and one 90 degrees circular segment with different straight final segment lengths, have been investigated....

Flight simulator investigation on the approach path parameters for MLS curved approaches

The present flight simulator study has been addressed to the evaluation of the approach path parameters for curved approach paths. A number of seven oblique approach paths has been investigated, varying in both straight final length and oblique angle. The investigation was carried out for various operating minima (decision height, runway visual...
