Abstract:
This document discusses three criteria currently under consideration for operating independent approaches to converging runways under Instrument Flight Rules. These criteria include the Worst-Case Boundaries, developed for the Federal Aviation Administration FAA by The MITRE Corporation the application of nonoverlapping Terminal Instrument Procedures TERPS obstacle clearance surfaces to provide protected airspace, developed by the FAAs Air Traffic Operations Service and Tower-Applied Visual Separation on Missed Approach, currently used in Chicago. A Single Criterion is then proposed which combines elements of the TERPS Criterion and the Worst-Case analysis. This criterion provides explicit blunder protection and its dimensions are functions of measurable navigation performance parameters. However, the decision heights obtained using the Single Criterion are generally higher than those obtained using the TERPS3 Criterion. This leads to the conclusion that, using the techniques described for the Single Criterion, decision heights lower than those generated by the TERPS3 Criterion may not be feasible for independent IFR approaches to converging runways. However, the Single Criterion may be useful in the future because it is directly related to aircraft performance on missed approach. Any improvements in navigation andor aircraft performance can be reflected in this criterion, with a corresponding lowering of decision heights.
