FSNAVIGATOR 5 KEY CODE
If that fails to give good results in the line draw then set the code like this If the Mag Heading is off and the VI is not pointing directly towards the ORABE fix it will wonder off course (lines) because theta and distance is not a requirement when using a VI. VI arcs are varibles unlike RF's which are based on the defined center point but the heading is very important so the arc will snap to the next fix of ORABE.

The objective is to get a small visual radius curve after the FAF of COMMB and a VI will do that if the correct Mag heading is used from COMMB to ORABE. The easist way to bend the approach once inside the FAF (COMMB) is to write the code with a VI

Arc Initial point (fix), Arc ending point (fix) and the key is the Arc Center Point which defines the constant radius turn between two database fixes, lines tangent to the arc and center fix. The RF leg needs 3 waypoints or fixes to work with. In most cases FS stays away from all these rules when bending an approach inside the IAF/FAF. There are a lot of rules in the 424 doc on how a RF leg is used when applied to a RNAV approach.
