When two aircraft are on a collision course, what is the appropriate action for each pilot?

When two aircraft are on a collision course, the rules of the air dictate specific actions to avoid a collision. The appropriate action for each pilot is to alter heading to the right. This is in accordance with established aviation protocols outlined in the aeronautical regulations.

The reason this is the correct action is that when two aircraft are approaching each other head-on, or nearly so, both pilots should turn right. This maneuver allows both aircraft to move in a predictable pattern, reducing the risk of a collision. By turning right, each aircraft effectively moves away from the other's flight path.

In this scenario, altering heading to the left could lead to confusion or increased risk of collision, as both pilots would be turning towards each other instead of away. Similarly, options involving climbing or descending while maintaining a straight course do not address the immediate need to change course and could lead to dangerous situations as altitude does not resolve the lateral conflict between the aircraft. Thus, turning right is the most effective and safe maneuver when on a collision course.
