LOW-COST RUNWAY GUIDANCE (VORLOC II).
Abstract
A simple low cost approach aid called VORLOC II was developed. The results of flight tests conducted indicate that the quality of the course line of VORLOC II is susceptible to its sitting. The course line had an average 95% course path bend amplitude of 0.41 deg with extremes of 0.17 and 0.63 deg. The equipment did not provide clearance throughout 360 deg. The maximum range at 2,000 feet altitude varied from 12.5 miles to 17 miles depending on the course width. The vertical polarization for a 20 deg bank either way had an average value of 18 microamperes. The equipment had temperature instability. During a period of heavy rainfall, the course line shifted 50 microamperes in 5 hours. (Author)
