PNEUMATIC WIND SHEAR SENSOR: A TOOL FOR METEOROLOGICAL INVESTIGATIONS AND FLIGHT MANAGEMENT

A simple and reliable pneumatic device for measuring wind shear (PWSS) was developed. It delivers the local change in horizontal wind speed with the height by measuring the difference of total pressure between two probes positioned in different heights. It can also be used to measure the change in horizontal wind speed along the flight path. The PWSS was used to investigate special meteorological phenomena, in particular nocturnal low level jets and the associated turbulence. The wind shear measuring device is applicable as wind shear indicator or as an additional sensor for an autopilot. The effectiveness of PWSS, as support for an autopilot during instrument landing system approach, is shown in a simulation program that uses local wind shear information as an additional input.
