9.G,

RNAV RNP, not RNP AR....

Currently the criteria only addresses vertical on approach, it does not address vertical for departure, nor any RF turns.

8168 is TF to TF design, (which is why the containments are so odd looking, accounting for flying inside and over the waypoint)and lays out a foundation for departures, however brief, much more a a placeholder to allow for private departure designs...

note this from 9905...
"The manual includes design criteria to aid States in the implementation of RNP AR approach procedures in accordance with the PBN Manual, Volume II, Part C, Chapter 6, Implementing RNP AR APCH. Similar criteria for departure procedures will be incorporated when developed."

Kijan,
The procedure must be in your navdatabase, because there are a few required points, such as the radial point, that you cannot enter. Essentially, how the box determines a turn, the beginning TF leg, to tan beginning waypoint of the RF leg, maintain "x" distance away from the radial point to the end waypoint of the RF leg, tangent to the TF leg...
