If ACARS is not available, through which channel is weight and balance information relayed?

• A. In-flight data link
• B. Dispatch
• C. Ground crew
• D. ACARS

Answer: (B)

Weight and balance data is handled by the dispatcher, who calculates the loading and CG and includes those figures in the flight release. If ACARS isn’t available, the dispatcher remains the source of that data and relays it to the flight crew through the standard release communications, ensuring the crew has accurate numbers to base performance calculations on. The in‑flight data link is the ACARS channel itself, so it can’t be used when ACARS is down. Ground crew may assist with loading, but they’re not the formal channel for delivering weight and balance data to the flight deck, and ACARS is the system rather than a fallback channel.
