outbound
Like all approaches the whole idea of any approach is to get visual (obviously) in the first place so any deviation from the surveyed tracks of an approach increases the chance of becoming a statistic revolving around those ugly letters "CFIT" (Controlled Flight Into Terrain).
Outbound interception. As long as one is actually heading in a direction to intercept the outbound track (assuming they are off it in the first place) then this is accepted as being suitable for safe flight in Oz. The different categories as in A&B/C&D & in some cases E cat's different outbound tracks attest to the fact that the need to be within 5 degs of any outbound track is essentially not required because often the difference of say Cat B to Cat C track exceedes 5 deg's in the first place.
So anyway you look at it fly accurately as possible & there should be little need to ponder this as one is in cloud, at night & juggling the torque guages to match the correct speeds...............now where would we be without LRN (GPS) these days? :-)
.....there's a great saying......applies to most things in life esspecially aviation........"chance favours the prepared mind"............simply be prepared !:-)
