When overtaking another aircraft, which side should a pilot overtake on?

When overtaking another aircraft, the standard practice is to overtake on the right side. This is in accordance with established aviation rules and regulations, which aim to ensure safety and predictability in air traffic. The right-side overtaking rule creates a uniform expectation among pilots, helping to reduce the risk of collision and misunderstandings while airborne.

This practice is similar to driving on roads, where defined rules help maintain order. By overtaking on the right, pilots can maintain a clear awareness of nearby aircraft movements, facilitating efficient communication and situational awareness.

The other options, while relevant in different contexts, do not align with the conventional rules for overtaking aircraft. Each presents risks that could lead to potential conflicts in the airspace.
