Determines the recommended holding pattern entry type (direct, teardrop, or
parallel) based on the aircraft's heading to the fix and the holding
pattern's inbound course.
The three entry sectors are defined by the AIM (Section 5-3-8). For a
right-turn hold, the sectors are measured clockwise from the outbound
course: parallel (0-70 degrees), teardrop (70-180 degrees), and direct
(180-360 degrees). Left-turn holds mirror this geometry.
Parameters
inboundCourseDeg: number
Inbound course to the holding fix in degrees (0-360).
headingToFixDeg: number
Aircraft's current heading or bearing to the fix in degrees (0-360).
rightTurns: boolean = true
True for a right-turn hold (default), false for left-turn.
