How do pilots make an escalated descent?

In page 10 of MMTJ´s VOR DME 1 & 2 approach chart for rwy 27, (for VOR DME 1) the altitudes are 5000ft at 120° until 11nm, turn to 283° and descend to 4300ft at 13nm, 3400ft at 8nm, 2800ft at 6nm and start final descent, and an altitude of 4300ft at 11nm, 3400ft at 8nm, 2800ft at 6nm and start final descent (for VOR DME 2).

I assume you have to calculate the TOD for the first altitude target (5000ft/4300ft respectively), and what do I do next?

I didn´t find the question in the forum nor in the internet.

You would calculate TOD to the first waypoint and keep going until the last waypoint.

Example: If you’re cruising at 20,000ft and the first waypoint asks to be at 8,000 ft, you would wait until you are ~36nm from there, then descend. The next way point requires you to be at 5,000 ft, you would wait until you are ~9nm from that waypoint then descend and so on.

So you calculate each altitude with the last TOD of the moment, 20000ft to 8000ft, 8000ft to 5000ft and etc…, is that correct?

That’s correct :)

Thanks! I´ll be able to descend correctly now.
