You are coming from northeast of SFB. ATC says "Cleared direct UDUZI,

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



UDUZI is the IAF, so once you're cleared for the approach, and you reach
the IAF, you fly the altitudes prescribed by the approach. For the leg
from UDUZI to UGMAH, that would be at or above 2000'.

I assume your question is due to the sector altitude of 2500 in the
region from UGMAH NW, between the 140 and 185 from UGMAH? Otherwise,
perhaps you could explain what it is about the plate that leaves you
with a question?


Assuming he is arriving between the UDUZI 185 bearing and the UGMAH 095
bearing (the TAA left base sector, AIM 5-4-5-d) he can descend to 2700
crossing 30 ATD from UDUZI. Then, once crossing UDUZI the altitude is
2,000.
