Which type of waypoint is the AGHAN fix?

The AGHAN fix is classified as a fly-by waypoint. A fly-by waypoint is designed to allow an aircraft to commence a turn before reaching the waypoint, enabling a smoother trajectory in navigation. This type of waypoint reduces the need for a sharp turn upon arrival, which is beneficial for maintaining both speed and safety, particularly in areas where flight paths are closely monitored or where other air traffic may be present.

In this case, how the AGHAN fix functions within a navigation context supports its categorization as a fly-by waypoint, as it helps facilitate efficient navigation without the abrupt angles that a fly-over waypoint might generate. A fly-over waypoint, on the other hand, would require the aircraft to directly pass over the waypoint before making any turn, which could be less efficient in certain flight profiles. The other options, including a waypoint with no altitude restriction and a mandatory reporting point, refer to different characteristics and operational purposes and do not specifically convey the nature of maneuvering required at AGHAN. Thus, the identification of AGHAN as a fly-by waypoint aligns with its intended operational use in navigation.
