Integrating Unmanned Aerial System (UAS) into controlled airspace may introduce communication challenges if there are time delays associated with the distribution of a common surveillance source of those UAS. Termed “information asynchrony” by Yuan et al (2012), an earlier, static image study showed large time delays had an observable impact on controller-pilot communication, but the effect was not present for time delays of less than 1 minute. A follow-up study is being conducted using an online ATC-flight simulator with professional pilots and controllers as participants. Effects on communication are being analyzed objectively through measurable characteristics of communication breakdown, and subjectively through trial questionnaire and survey. Limited results to-date showed no observable effects on pilot-controller communication with time delays of less than 100 seconds and illustrated the challenge of identifying measures robust to the inherent variability in working methods and communication styles.
