Alpha…
That's a great explanation and answers a lot!! Thank you!!
I guess my question at this point would be….
If it's up to us to fly either approach, why did the approach controller advise us, "Well then you flew the correct approach"?
Some have said we would be correct in flying either approach in absence of a specific approach, but to me, what the ATC guy said would imply that had we flown the Y approach procedure, it would have been the "wrong" approach.
So far, I've not found nor have I been shown here any documentation in black and white saying something to the effect, in the absence of a specific procedure, you can fly any procedure (ILS specific in this case) you want".
Maybe there is no such thing. Then again, I may be so blind as to not see something already discussed here. :-)
