Mark Goodman, director, product management, Honeywell Aerospace said, " The achievement of the TSO certification for the Honeywell Aspire 400 system is a major milestone for the aviation industry as the system can significantly increase safety and efficiency of air travel. Aspire 400 provides pilots with improved voice communication with Air Traffic Control as compared with high-frequency radio. Additionally, Aspire 400 increases efficiency by enabling real-time data transfer between aircraft and the ground. This can help in situations where rerouting is necessary to avoid bad weather. "
