When overtaking another aircraft or vessel on water, what must the pilot do?

The correct answer involves altering the aircraft's heading to ensure it remains well clear of the other aircraft or vessel. This action is essential as it prioritizes safety and adherence to the rules of navigation. When overtaking, it's crucial to avoid any potential collision, which means the pilot must ensure adequate distance from the other vessel. By changing the heading, the pilot can safely maneuver around the other craft, maintaining a safe buffer zone and enhancing situational awareness.

The other options would not meet the safety requirements expected during such a maneuver. Accelerating past another vessel could create a risk of collision if the other vessel is not aware of the maneuver or if distance isn't properly managed. Taking the path of least resistance might imply a more random approach, potentially increasing the risk of conflict with the other aircraft rather than ensuring a safe overtaking procedure. Maintaining a steady course without alteration could lead to a dangerous situation if the other vessel is moving or if there isn't adequate spacing established beforehand. Thus, altering the heading is the most responsible and safest practice when overtaking.
