An ABEAM waypoint results from which type of entry?

An ABEAM waypoint is created when the aircraft is on a course that is perpendicular to the desired track, typically at a point where the aircraft is at a right angle to the next waypoint. This occurs as a result of a DIRECT TO entry. When a pilot selects a waypoint using a DIRECT TO entry, the navigation system calculates the most efficient path to the waypoint, taking the aircraft directly to it. This often leads to a scenario where the aircraft reaches an ABEAM position relative to the earlier waypoint, effectively placing it on a straight path toward the target destination.

In contrast, FLY-BY and REV BEFORE entries refer to navigation tactics that involve either intentionally passing near the waypoint or requiring a turn before reaching the waypoint. The DEFINE WAYPOINT option is not relevant here since it involves the creation rather than the type of approach to an existing waypoint. Thus, the nature of the DIRECT TO maneuver is what establishes the ABEAM waypoint effectively.
