Which illustration indicates that the airplane will intercept the 060 radial at a 60° angle inbound when maintaining the present heading?

To determine which illustration indicates that the airplane will intercept the 060 radial at a 60° angle inbound while maintaining its present heading, it's important to understand how radials and bearings work in relation to an aircraft's heading.

When an aircraft is tracking toward a VOR beacon, the radials extending from the beacon represent specific headings (in degrees) that can be intercepted. In this context, the 060 radial implies that an aircraft must be on a heading of 060° to remain directly on that radial.

If the airplane is currently on a heading that does not perfectly align with the 060 radial, the angle at which it will cross that radial is determined by the difference between its current heading and the radial itself. An intercept angle of 60° suggests that the aircraft is approaching the radial from a direction that forms a 60° angle with the direction of that radial.

In this case, the illustration marked as the correct answer effectively depicts the geometry of the situation. It shows the aircraft's heading in relation to the 060 radial, illustrating the correct angle of interception. The visual orientation should confirm that at the aircraft's current heading, when it reaches that 060 radial, it will do so at the designated 60° angle of
