Brain fart, sorry! I should have said you can be at or above the level segment depicted on the chart but the FAF shall be crossed at the mandatory altitude.

Pilot should actually have 2000 at FAF. The "mandatory" label which instructs you to be exactly at 2000 for the full intermediate approach segment (pointed out by Vessbot) had been added by Jeppesen.

According to the Jeppesen chart guide the bold altitude specifically refers to the altitude at FAF/FAP (as opposed to the colloquial platform altitude).

The Lido plate is more clear. The Jepp way of doing things is ambiguous in this case but the mandatory altitude at the FAF/FAP is not in doubt either way.

The "mandatory" label doesn't instruct anything about the segment before the fix, it's about the fix itself. And it's not "added by Jeppesen" as in Jeppesen invented it, it's there because the source data says to, unless it's a charting error. It's simply Jeppesen's presentation of a mandatory (instead of minimum, which is the common one) altitude, equivalent to the 5500 here, from FAA AeroNav charts:

A Jepp altitude with no note (#4 in Oggers' post above) is equivalent to the 2500 here, and is the common one (minimum, aka "at or above")

Thanks for correcting. I meant J. put it there on their own will (charting error), but that is also not true. The restriction is actually visible in the LIDO graphics too.

Had a look last night for the Egyptian AIP, despite some improvements in the Internet realm it is not accessible online.

Then I had it slip away, apologies.

The only reason for having "mandatory" heights depicted on letdown chart is to free the space above..
Jeppesen is a copy company and does not design approach charts, the state does..
I suspect it is a design error by the state but you have to comply with it. You should cross 12d at 2500 ft & 7.4d at 2000 ft.....
