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....

DME-derived positions compared with MLS- and ILS-derived positions

From recorded Distance Measurement Equipment (DME) data during Microwave Landing System (MLS) flight trials performed at London Gatwick Airport (April 21 - 26, 1989) using the NLR Fairchild Metro II Laboratory Aircraft, the position of the aircraft was determined by post-processing and compared with the MLS- and ILS-derived positions. This...

Results of MLS procedural interception flight trials performed at Manchester Airport

In July, 1988, flight trials have been performed on the newly installed MLS equipment at Manchester Airport (UK), using one of the laboratory aircraft of NLR, a Fairchild Metro II with programmable avionics systems including a basic MLS receiver as an "Avionics Research Testbed". The aim of the tests was to prove that aircraft with basic IFR...

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...

Investigation on MLS approach path interception and transition techniques: part II: flight simulator investigation

Due to the wide coverage volume of MLS, in both azimuth and elevation, the system enables the introduction of new approach and terminal area procedures. For several years the NLR has been investigating the potential of MLS with respect to the execution of non-straight-in approaches. In an earlier theoretical study four MLS-guided interception...

Investigation on MLS approach path interception and transition techniques: part I: fast-time computer simulations

MLS provides the possibility to define non-straight-in approach paths and to use more advanced interception procedures. From an ATC point-of-view it became necessary to structure this capability as a prerequisite in order to make a realistic use of the potential capabilities of MLS. Four different MLS approach path interception procedures were...

A simulation investigation on the feasibility of curved approaches under MLS guidance. Revised edition
