Yes, it is nice when people file flight plans that follow real world procedures. I do the same when I fly. However, you must follow ATC instructions, and often times, that will be different than your flight plan. I know of several radar controllers that try and implement SIDs and STARs into their patterns, but it will never be perfect.
So first off: you wouldn’t actually put in your approach until approach says what exact STAR you will fly. Also you would know what exact runway you will use as winds or other factors can change so that’s why you don’t put your approach in in real life until assigned one. In IF as @BennyBoy_Alpha said controllers at least the ones I have talked to try to implement SID/STARS but it’s hard.
I try to fly with the approach charts open so when I am assigned a runway, I can plug in the appropriate waypoints into my FP. Most of the time, it doesn’t matter because approach controllers in IF rely quite a bit on vectoring.
(I was also referring to using the established procedures for ILS and RNAV, not only SIDS/STARS)
Also @KyleBoas you ever have any questions about ForeFlight I use it in IF and in real life quite often so if you ever have any questions feel free to ok me!
As a controller and pilot, I find it much more useful if you use real world procedures, as it keeps the airspace more organized. I most likely speak for all controllers when I say, please use real world procedures, it keeps everything just a bit cleaner.
I do the same thing. I pick where I want to start and see what real life flights are there and pick one I want to do as long as the matching aircraft and livery are in IF. Then I pull up the real life terminal map and pick an appropriate stand to start from. I make my flight plans in simbrief, copy it into IF, set my weights and fuel as stated in the plan, get the charts out (especially the taxi diagrams) and off I go.
One, I simply prefer to be prepared, and two, it gives controllers a clear picture of what I’m thinking. Obviously, aside from cruise, you’ll usually never fly the plan exactly. Even if I’m going into an uncontrolled airport with zero traffic I’ll usually shortcut the approach if it’s safe to do so and visibility is great.
Always. I use my flight plan as a way to show ATC what I want to do, and how I want to do it. Usually IFATC will give me the runway I wanted, but sometimes they won’t, and I adjust for what I was given. Always listen to ATC over your flight plan. They can see what you can’t.
