Wind shear on the approach: An investigation on the infuence of a tower measured wind environment on the symmetric motions of a simulated aircraft in an automatic approach

Measured wind profiles from the Royal Netherlands Meteorological Institute 200 m meteorological tower at Cabauw have been used to estimate wind shear effects on the symmetric motions of an approaching aircraft. Wind profiles as well as an automatically approaching DC-9 aircraft have been simulated on an electronic analog computer. The study...

Simulation of the automatic approach of a twin-engined jet transport

In order to obtain insight in the accuracy of automatic approaches, the symmetric motions of an aircraft, stabilized by autopilot and autothrottle, are simulated on an electronic analog computer. The aircraft tracks an I.L.S. glide path, being disturbed by I.L.S. beam bends, atmospheric turbulence and wind shear. The deviations of the aircraft...
