You are coming from northeast of SFB. ATC says "Cleared direct UDUZI,
maintain 4000' until established, cleared RNAV 9L approach."

When do you descend below 4,000 and to what altitude?



30 miles from UDUZI, 2700 MSL.



correct.



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?

Too conservative and wrong. The altitudes within a TAA are operational
altitudes, otherwise they would not contain an altitude with an underscore.
