Mandatory Altitude Jepp Chart
Good Day All,
It's been a while a have this question in mind. I did my research on the Jepp manual but I didn't find anything conclusive. Is a level off between 12D and 7,4D mandatory? or the constraint 2000 Ft only apply at the FAF 7,4D? Awaiting for your comments and doc reference if you have one.

Step 1: check the AIP ? It kinda opens the question, how quickly you'd need to descent to comply with the author's intent...

Isn't that the situation if the word MANDATORY had not been there?

Interesting that 'mandatory' is also published for the procedure turn at 2500'. I've never seen this before. Regarding the 2000' & 7.4nm, it is usual to show 2000' AT 7.4nm. If the same was true for the procedure turn it should show 2500' AT 12nm.
It is bizarre by it being an unusual display. I wonder what other chart manufacturers depict? After all, Jeppesen publishes only the information supplied to them by the state. |

Lido shows it a lot more clearly. Unfortunately this is another example of Jeppesen's lack of standardization when it comes to their charts, its like the magic phrase 'authorization required' on CAT II and III minimums (stating the obvious), but the same note on RNP-AR procedures (which are usually called only RNAV still on many of their charts).
|
Jeppesen could show the same as Lido, but for some reason decided not to, and included the M word. Still curious.
|
Lido make it crystal clear!!
Thanks for your answers guys. |

hahaha...just remembered, the term 'briefing strip' is a Jepp trademark!
Jepp Definition: MANDATORY ALTITUDE — An altitude depicted on an instrument approach procedure chart requiring the aircraft to maintain altitude at the depicted value All altitudes depicted in the profile view are MINIMUM altitudes unless specifically labeled otherwise. All altitudes are above mean sea level in feet (AMSL). 5 — Maximum altitudes: may be abbreviated "MAX". 6 — Mandatory altitudes: abbreviations are not used. 7 — Recommended altitudes: abbreviations are not used |

https://www.volpe.dot.gov/ not at Jeppesen. |
Does the ‘Mandatory’ labelling follow ICAO standards and recommended practices? Does the USA/FAA follow ICAO in this matter; if not have they declared a deviation from ICAO? Alternatively if the FAA and ICAO are in agreement, then are ‘volpe’ / Jepp, etc out of step, and are they, and what they publish subject to FAA oversight? |

Just wondering if we had made any further progress on this or if we have anything definitive.
It doesn’t appear to me to make any sense to be using stepdown attitudes nowadays with the systems we have on board and our ability to fly constant descent CDFA approaches. Interested to hear peoples opinions 🤔 |
I'd take it to mean that you must descend to 2000' once passed 12nm. Could it be due to traffic conflicts at another field? Or to separate departing traffic?

Old topic this one, but I asked a similar questions not long ago. It's just a Jeppesen thing, it's mandatory to be at the FAF at or above 2000 ft, not below.
