A Study of Conflict Resolution Timeliness and Impact of Horizontal Maneuver Parametric Settings

Abstract

The tradeoff between efficiency and trajectory uncertainty is considered when evaluating how early to initiate a conflict resolution maneuver. Four fast-time simulations are conducted employing a well-established prototype conflict detection and resolution algorithm to quantify the fuel and delay penalties associated with deferring resolution maneuvers in order to increase confidence in the conflict prediction. Additionally, the effects of using finer resolution when selecting conflictresolution heading maneuvers are evaluated. Results indicate that early initiation of resolution maneuvers reduces airborne delay and fuel consumption, but only slightly. This finding suggests that it may be operationally desirable to forgo the modest delay and fuel benefits associated with earlier maneuvers in order to buy down the uncertainty that is inherent in trajectory predictions with longer time horizons.

Exploring Performance Differences Between UAS Sense-and-Avoid Displays

“…JADEM's conflict detection logic evaluated and prioritized surrounding traffic according to their predicted threat level. In some experimental conditions, JADEM provided participants with text-based horizontal and vertical recommended maneuvers through its conflict resolution algorithm, Autoresolver-AD (Pankok & Santiago, 2013).…”
