What is the compass indication when turning left from a south heading?

When turning left from a south heading, the compass behavior is influenced by a phenomenon known as magnetic deviation, particularly when turning. As the aircraft begins to make a left turn, the compass will initially lag behind due to its need to catch up with the new heading. When turning left, the compass will momentarily show a reading that is less than complete, but more importantly, if you are turning left at a fast rate, the compass will indicate a heading that is lower than the actual heading you are flying into.

In this specific scenario, if the turn is executed rapidly, the compass can show an indication of turning to the left, but due to the aforementioned lag or discrepancy in compass fluid motion, it may display an exaggerated left turn, leading to an interpretation that it is indicating a left turn at a faster rate. This response aligns with the physics of how magnetic compasses function in relation to turns, reinforcing the importance of understanding compass behavior during maneuvers.
