A third attitude indicator powered from its own independent source must be aboard which type of aircraft?

• A. Small general aviation aircraft
• B. Light sport aircraft
• C. Large turbojet aircraft or any turbine powered transport category airplane operated by an air carrier
• D. Any recreational aircraft

Answer: (C)

The requirement for a third attitude indicator powered from its own independent source is primarily mandated for safety and redundancy in large turbojet aircraft or any turbine powered transport category airplanes operated by an air carrier. This requirement stems from the operational complexity and safety standards imposed on commercial air transport. In large transport category aircraft, the reliability of the instrumentation is critical for safe operations, especially in adverse conditions. Having an independent attitude indicator serves as a safeguard against failure of primary flight instruments, thus enhancing situational awareness for pilots and ensuring compliance with safety regulations. Other types of aircraft, such as small general aviation aircraft, light sport aircraft, and recreational aircraft, typically do not have the same stringent requirements mainly because they operate under different regulatory standards that prioritize simplicity and cost-effectiveness for the types of operations they conduct. Therefore, they are not mandated to have a third independent attitude indicator, highlighting the specific need for such redundancy in commercial aviation contexts.
