ABSTRACT:
Wind conditions and anomalies in the proxmity of an airport runway approach and departure flight path may be monitored by the tethered deployment of a plurality of extremely light and expendable airborne vehicles such as kites or balloons in an array spaced from the projected runway ends and at graduated altitudes commensurate with the glide path altitude at a respective tether point. Vehicle flight conditions such as vertical and horizontal tether line repose angles and tether line strain are measured by ground level instrumentation and transmitted to appropriate receiver and display equipment. The measured data is compared to calibrated vehicle flight response to conclude wind direction and velocity at the vehicle flight position. Comparison of wind conditions at two or more flight path positions and altitudes will reveal the presence of operational conditions hazardous to aircraft. A remotely controlled, data measuring and telemetering vehicle tether is also disclosed which may be used in the aforedescribed combination or singularly for other aerological monitoring purposes.
