As many of you have figured out, I'm in the final stages of earning my Instrument rating. In preparation for the checkride, I had a couple related questions about V-airways and changeover points. According to the AIM, a COP can either be marked or (obviously) take place at a fix that defines a dog leg. My question is what degree of change in course would be considered a dog leg? I'm looking at V1 down the East Coast and there is a 5 degree change in course at the WALLO intersection. Would this make WALLO a COP despite the fact it is only about a third of the way along the airway? Also, the other radial that defines the fix (CRE 034) has a DME marking at the fix. I assume a DME fix indicates that the radial can be picked up at that distance as well, but wanted to verify this.
Sorry if these questions are a bit strange, but I know tech/ops is the best place to get a fast and accurate answer from people that know!
If a visual helps, the route in question is on L-27, panels B and C.
