When to descend

Hmmmmm....I'm not sure I buy this. The clearance stated "...maintain
4000'
*until established*..." which to me says that I'm to remain at 4000' until
I am on a *charted* section of the approach. Simply being in the TAA
does not mean I'm on a charted section of the approach. For this
clearance,
I would say I'm on a charted section of the approach after crossing the
IAF
(UDUZI). I would not descend below 4000' until after crossing UDUZI, and
then I would descent to 2000' as depicted. Or am I being too conservative
here?


TAAs are published portions of the approach, when you cross the TAA boundary
you're *established* on the approach.
