Which DTS function defaults to off upon startup?

• A. AGCAS
• B. DBTC
• C. PGCAS
• D. DTC

Answer: (B)

The function that defaults to off upon startup is the Database Transmission Control (DBTC). This is crucial in avionics systems because having certain functions inactive at startup helps prevent unintended behaviors during the initialization of complex systems. The DBTC serves to manage the transmission of data within the system, ensuring that any updates or changes to the database are controlled and don’t interfere with other critical operations immediately upon startup. In contrast, other functions such as the Automatic Ground Collision Avoidance System (AGCAS), the Pilot Guidance Collision Avoidance System (PGCAS), and the Data Transfer Capability (DTC) are typically designed to be in an operational state when the system powers up. This ensures that the avionics systems are immediately available and responsive for safety-critical operations right from the start. These elements are fundamental for maintaining operational readiness and safety in aviation contexts.
