I missed that note. But, that note is somewhat different in the 530
manual because not reference is made to creating a position using the
intersection of two radials.
So apparently this radial/radial option was a new feature in the WAAS
series.
The functionality is in the 530 (A) but it's not explicitly stated in the
old manual. There is a note in that section but the statement about using
two radials to create a user waypoint is not there.

Thanks for your help.
Indeed it does work in the 530 trainer. I guess I was hung up on the
reference waypoint changing after I created the intersection. The
handbook says that doesn't matter, which of course it doesn't. ;-)
The 530 and the 530W created a slightly different position for the
intersection of V-264 and V-137.
And, the official FAA position is slightly different than those two.
The difference is reasonable for an en route airway intersection. I
wouldn't want to be designing IAPs using this method, though. ;-)
Intersection of V-264 and V137:
FAA:
34 05 49.9
116 54 33.8
530:
34 06 02.0
116 54 50.7
530W:
34 06 01.9
116 54 50.2
It would be interesting to construct this waypoint at a location with a
different mag var than the location I used and see if that would affect
the device's calculation. Next time.
