N2  - This article considers a method to address the problem of two aircrafts encountering one another during the planned descent of the higher-flying aircraft. The author considers conflict detection, reaction, and strategical resolution of conflict (conflict avoidance maneuvering), noting that these components must all be completed in a relatively short period of time. The author discusses how the traditional ground-based control systems have to be enhanced by the autonomous anti-collision and anti-conflict airborne systems. Avoidance procedures with descent behind the intruder are discussed. The author recommends procedures for this situation, based on an in-flight conflict resolution model modified from classical works about conflict detection and resolution. Two avoidance procedures are described: avoidance procedure with direct descent behind the intruder from delayed TOD (top of descent); and avoidance procedure with descent behind the intruder from planned TOD with a safely altered angle of descent. The author concludes that avoidance procedures with descent behind the intruder are feasible if and only if initial vertical displacement between aircraft in a conflict encounter exceeds the vertical separation minimum.<p />
