If maintaining zero wind, what would be the expected track if the aircraft remains on the course provided in illustration 1?

The expected track of an aircraft when maintaining a specific course in zero wind conditions can be determined by understanding how the course relates to the navigational aids or geographic points. If the aircraft is positioned at a predetermined bearing relative to a navigation station and remains on this course, the angle defined will dictate its track.

When considering the course indicated in the illustration, if the aircraft is expected to maintain an outbound path from the station at a specific angle, that suggests it is following a radial that diverges from the station. The choice indicating a 60° angle outbound from the station aligns with the concept of a radial navigation pattern, where the aircraft is effectively maintaining the designated course while following the curvature dictated by its navigational aids.

In contrast, other options represent different types of navigation that either maintain a course that does not correspond to the outbound trajectory or deviate from the intended path. The zero deviation option suggests a straight course without any correction, which does not apply in every navigation scenario. The northbound angle also points to a specific geographic direction rather than an outbound navigation track.

Thus, the correct understanding of the aircraft's expected path, given that it remains on the indicated course in zero wind, leads to the conclusion that it follows a 60° angle
