SMO aproach on MMMX

[drbit]

Hi mates and Captains here

I have a few question for you, in the case of anyone has flying to MMMX. In FSX and FpX i have MMMX as base airport, since i live about 5
milles, actually my home are on the ILS path, hehehehe

well my 2 question are.
1) when i come from Mexican Gulf, i try to avoid the departures routes of MMMX, when the 5L&5R are the take-off runways, because the
original fligh-plan send me to PBC, then MEX. Well the question are, what is the true path from the Mexical Gulf, to intercept the SMO
aproach. i do the following... NAU-PAC-SLM, then SMO for approach vector.

2) here in mexico we have 2 level for transition altitude, acctually one are FL195 for TL, and 18500 feet for TA, for my experience on real
cabin, ( i have fortune to 3 flights go on the flight deck ) the captian use the TL when the desent for the approach to MMMX, but i ignore if
are the same TL for climb, or use the TA (18500 feet ). so my question are, which are the TA o TL in Mexico airspace.

Chears!!
