Why do airline captains sit on the left-hand side?

Following on from my story a few days ago titled "Why do we board aircraft from the left"? Have you ever wondered why airline captains sit on the left.

In road transport, the position of the driver in motor vehicles varies between the left or right-hand side, depending on the country for which they are manufactured. In contrast, air travel is more internationally standardized, particularly regarding the captain's seat in the cockpit, which is universally on the left-hand side. This practice originates from the era preceding jet engines, rooted in the mechanics of early rotary engine aircraft, like those used in World War I.

These early aircraft had a propensity for left turns, aligning with the torque produced by their clockwise-spinning propellers. Conversely, turning right was more challenging, requiring greater control and rudder input to counteract the engine's torque.

This ease of left turning led to operational practices that established the left-hand side as the captain's seat. Airports, for instance, adopted traffic patterns that favored simpler left turns. As these patterns became predominantly left-oriented, it naturally became standard for the captain to sit on the left-hand side, positioning them on the inside of the turn.
