Altitudes that come with STARs

Hey, do we have to follow the altitudes that come with the STAR when we add it to the flight plan or can we just descend to 3000 feet at the beginning of the ILS cone? (I’m trying to keep it as realistic as possible but I’m not sure about that and that’s why I’m asking)

I believe those altitudes are only recommendations and you do not have to follow them. However, I always follow them as they are accurate and realistic.

Oh ok… so just to get this clear, if I’m trying to be realistic, should I really follow those altitudes?

Yes, if you want to be realistic. They are actual established altitudes.

Alright, thank you so much!

While yes, following the preset STAR altitudes is realistic, you can be even more realistic. In Infinite Flight, procedure altitudes are set points. In real life, altitudes are shown with lines above, underneath, or on both sides of them. This provides information on whether you should be above, at, or below certain altitudes.


Let’s take a look at SFO’s BDEGA3 Arrival:

Hope this makes sense. If you have any other questions, don’t hesitate to ask!

But please keep in kind that very often they are at or above altitudes, so please don’t fly at 5000feet 30NM away from the airport. Only well to really tell is, as @lucaviness said, to use the IRL charts.

Probably an IFATC can confirm how it is with decent via STAR clearences, but I believe they are treated as at or above as well.
