Incorrect ADS data can affect which of the following functions?

• A. Fuel temperature readings
• B. Flight path guidance, autopilot operation, and flight path stabilization
• C. Cabin lighting intensity
• D. Cargo door operations

Answer: (B)

Air Data System information provides the essential airspeed, altitude, and related data that the flight guidance and control systems use to command and maintain the aircraft along its planned path. When this data is incorrect, the autopilot can misinterpret speed and climb/descent requirements, and the flight path guidance and stabilization logic may struggle to hold or follow the intended trajectory. That’s why incorrect ADS data most directly affects flight path guidance, autopilot operation, and flight path stabilization.

In contrast, fuel temperature readings come from the fuel system sensors, and cabin lighting or cargo door operations are controlled by other electrical and door-control systems, not by air data.
