In game, depending on traffic, the ATIS will announce if Arrival and departure procedures are required or recommended. Personally, I would always rather having an arrival procedure because that way I know I’m getting myself in the “pattern” with other pilots.
Having an arrival procedure will also make the radar controller and tower controller, if applicable, happier because then at least you will be worked in the same pattern with other pilots.
As for approach procedures, they can be helpful when we check your information to just give you an approach based on what you entered instead of having you request one.
At the end of the day, I would much rather someone have an arrival procedure over an approach procedure.
Which runway do you mean (or rather which procedure)?
Edit: I checked and SIE is an IAF for the ILS for the RWYs 18L/R, but isn’t connected to any active STAR. It might be a point where you end up after a missed approach or after a direct, but with today‘s RNAV equipment you would fly a STAR and use one of the other transitions for the ILS (or get radar vectors). If you have any further questions, especially regarding an exact procedure please feel free to ask!
Thanks a lot for your answer. So if I am not wrong. All IAF must have a previous STAR.
It can be an embarrasing question but, what is a direct?. Is it landing without a STAR? Just IAF.
Unfortunately, LEMD is not frequently used by ATC so I can´t ask vectors to approach or land. I´m looking for some planes that comes from the north like EGLL, that lands via SIE. Also playing IF, I want to put all realism in it.
Not necessarily, no. Most have though, that’s true. In Germany you mainly use RNAV transitions to an IAF directly on the localiser instead of STARs, which would be another option.
Not at all embarrassing. A direct is a clearance (Example: ”Cleared direct VEBIT“, with VEBIT being a waypoint name). So it’s a clearance to turn direct to a certain point (VOR/NDB/Waypoint). It isn’t implemented in IF though in the Moment.
If they approach vie SIE in real life than that’s most likely via vectors as I can’t find a STAR leading to it. If you want to fly via SIE, I would check if they initially fly a STAR or not if you want to fly the same route, and proceed from a point on the STAR direct to SIE if you want.
