Which illustration indicates that the airplane will intercept the 060 radial at a 75° angle outbound, maintaining the present heading?

To understand why the illustration that shows the airplane intercepting the 060 radial at a 75° angle outbound while maintaining the present heading is option B, one needs to visualize the basics of navigation and radials.

When navigating with VOR (VHF Omnidirectional Range) radials, the radial is a specific line of bearing radiating from the VOR station. The 060 radial extends outward from the VOR at an angle of 60 degrees from true north.

An airplane that is maintaining a present heading toward the radial would ideally cross the radial at a specific angle, which is indicated by the intersection of the aircraft's track and the radial line. A 75° angle outbound means that the aircraft is flying at a heading that is 75 degrees relative to the radial line, which suggests the approach towards the radial is not head-on but at an acute angle, allowing for an outbound course from the specified radial.

Illustration B accurately depicts the aircraft’s current trajectory aligned in such a way that it's set to intercept the 060 radial at the desired angle. The visual representation is critical in aviation to ensure correct navigation and understanding of how to maintain the appropriate course over the ground.

The relevance of the angle shows how the pilot should adjust
