NextGen Flight Deck Data Comm: Auxiliary Synthetic Speech Phase I

By U.S. Department of Transportation

Data Comm a text-based controller-pilotcommunication system is critical to many NextGen improvements.With DataComm, communication becomesa visual task. Interacting with a visual Data Comm display may yield an unsafe increase in head-down time, particularly for single-pilot operations.This study examined the feasibility of supplementing Data Comm with syntheticspeech.To this end, thirty-two pilots flew two experimental scenariosin a Cessna 172 Flight Training Device. In one scenario, ATC communication was with a text-only Data Comm display, in the other, communication was with a text Data Comm display with synthetic speech that read aloud each message (i.e., text+speech). Pilots heard traffic with similar call signs on the party line and received a conditional clearance (in both scenarios); in either scenario, pilots received a clearance that was countermanded by a live controller. Results indicated that relative tothe text-only display, the text speech display aided single-pilot performance by reducing head-down time, and may have prevented participants from acting early on the conditional clearance.Supplementing text Data Comm with speech did not introduce additional complications: participants were neithermore likely to erroneously respond to similar call signs, nor to ignore a live ATC voice countermand
