What does the diamond on the pitch trim indicate?

The diamond on the pitch trim indicates the takeoff trim setting, particularly when the center of gravity (CG) is aft of 236 inches. This visual cue is critical for pilots as it helps them ensure the aircraft is properly configured for takeoff, enhancing performance and stability during this crucial phase of flight. An appropriate pitch trim setting is vital to achieving the correct nose attitude, ensuring that the aircraft climbs efficiently and safely.

Understanding the importance of pitch trim settings assists pilots in optimizing aircraft handling characteristics, especially in conditions where the CG may shift, which can significantly affect flight dynamics. Hence, the diamond serves as a reminder to ensure the trim is adjusted correctly before initiating takeoff, particularly when dealing with an aft CG scenario that could otherwise lead to control difficulties.
