EVALUATION OF LOWER ILS MINIMUMS FOR LIGHT AIRCRAFT,
Abstract
120 ILS approaches were flown under simulated IFR (hooded) conditions by 17 pilots in 6 types of light twin aircraft to test the ability of pilots to align for landing or to execute a missed approach at minimums lower than 200 feet height and 1/2 mile visibility. A decision height of 100 feet was used during the entire project. Although only 80 percent of the scheduled landings were completed, pilots indicated that with normal runway lengths (5000 feet) most runs scheduled for landing could have been completed. The altimeter errors at the 100 foot decision height ranged from -80 to +45 feet, and seemed to cause the major problem. Missed approach data indicate that the missed approach obstacle clearance must be revised if minimums below 200 feet are to be approved for this pilot group. (Author)
