Hi all I would appreciate clarification of the followingIs it appropriate to plan a flight and PICK your sid /transition for the direction of flight, and then send in the flight plan. Will atc try to accomodate the planned routing , or;should one wait for the ifr clearance based upon flight plan routing assuming no sid/trans and the atc will assign the appropriate sid based upon the direction of flight and active rnwyI like to plan the flight, using pref routing, and choose the sid/ trans , send in my flight plan etc. Quite often I find atc providing a change to the sid and transitionWhat works best for everyone. ( I typically use fsbuild ) .Thanks in advancePeterPeter K P.EngCF-MMZToronto Ontario CanadaPMDG 747,737and 747FLevel D 767PSS Airbus pro A340-300In reality, a Mooney 201 Pilot

Peter,This is really dependant on the part of the world you are flying in. In short, VATSIM Controllers strive to follow the procedures used in the real world.

What Norman said.For example in the UK, you put the end waypoint of the SID you want to use. Usually this is the same for whichever runway you use e.g. from EGLL going west towards Ireland it will be a CPT (Compton) SID. Whyen you call for clearance the controller will tell you the actual SID based on the departing runway e.g. 09R is a CPT5J, 27L is CPT3G, 27R is a CPT3F. But what you file is a flightplan that looks likeEGLL CPT L9 STU M17 VATRY EIDWYou have to watch out for airports which use different final waypoints depending on the runway e.g. at EGLL if you are going north, the SIDS are via WOBUN on 27s and via BPK on 09s!RuthVATGOV7Vice president, Communications, VATSIM
