Based on illustration 5, which radial will the airplane intercept if it turns to the designated heading marker?

To determine which radial the airplane will intercept upon turning to the designated heading marker, it's crucial to consider the relationship between the airplane's heading and the radial system. In aviation, radials are typically referenced from the center of a VOR (VHF Omnidirectional Range) station and are expressed in degrees True or Magnetic, depending on the setting.

When the airplane executes a turn towards the designated heading marker, the specific radial it intercepts will depend on the magnetic or true bearing indicated on the aircraft’s navigation instruments. The designated heading marker points directly toward the VOR station from the aircraft’s current position.

If the heading marker shows that the airplane should be turning towards 060 degrees, the aircraft will intercept the 060 radial, meaning it is following a course that leads to the VOR station along the radial designated as 060. This implies the airplane is approaching the VOR on a heading that is aligned with the 060-degree radial.

Understanding the principles of navigation, particularly how radials function relative to the VOR station and how headings are interpreted on a compass or navigation display, clarifies why the 060 radial is the correct answer in this scenario.
