A Curved Approach With ILS/Loran-C

Richard H. McFarland

Abstract:	This paper suggests the joint use of Loran-C and 1I.S to provide a capability to execute curved approaches to landing. The concept of curved approaches presented, while somewhat different from those of RTCA/DO-198, involves use of a blend of the two systems for executing a curved flight track along with utilization of a contemporary HSI cockpit presentation for the pilot. A set of assumptions is given. A comparison of positional accuracies available from the two systems results in their being deemed adequate for a final approach fix of 5 miles near where the transition from a curve to a straight line would take place. The conclusion is reached that a combination of the signals from the two systems along with computational and display capabilities on board the aircraft can provide for other than the common, straight-in approach to landing.
