The SID HAS TO BE PUBLISHED FOR A REASON, or they wouldn't even have it in the first place. Hi, Let's put this in another perspective. Imagine a case at another airport than KORD where there would be only SID as well and this SID would not start by a vector but a 90 degrees turn to either side. The ATC is clearing you for a departure on runway heading, then vectors. Would you follow the SID without being cleared by the ATC ("because there is only one SID") you may put yourself and the ATC in a tricky situation with a turn where the ATC would expect you to maintain the runway heading for a while. If ever everything happened because of that... I'm pretty sure you would have the worst difficulties to argue during a trial that you followed the SID and not the ATC instructions because there was only one SID! Off course, in KORD the SID is vector as well but still you would do something that you were not cleared to and therefore something that the ATC would not expect you to do. If the ATC wants you to comply with the restrictions of the SID, they will either clear you for the SID or give you the instructions during the clearance.

That's all I want to know. Correct. Unless you are told to do something, don't do it. They should provide alternate instructions - like "after departure fly runway heading" - but again I'll go back to predictability. If you aren't told to climb, descend, or change to a new heading, would you do so? No. Kyle Rodgers
July 31, 20178 yr I suspect ORD2 is used with light aircraft where the instructions are relevant and the note for non-DME equipped aircraft may apply. It has been on the books for many decades, at least since I got my license in the 70s. Dan Downs KCRP
July 31, 20178 yr Just for everyone's clarification I have flown out of KORD many times (actually I was even based there for a year) and, every time I can remember, we were assigned the ORD departure in our ATC clearance. We usually just create some range rings on the fix page for reference to the altitude restrictions. Tom Landry
July 31, 20178 yr Just because a SID contains no lateral instructions doesn't mean it isn’t a real SID or won’t be issued in the clearance. If it contains any special instructions it needs to be issued to make the flight crew aware of those instructions. We have the same type of SID at Paine Field and I always received the paine4 departure as part of the clearance, even when the initial heading is different from the published headings. Brian W KPAE

August 1, 20178 yr Well, if you're willing to fly far enough, you can reach KFJK flying West from KORD....it's called the scenic route! Mark Trainer Mark Trainer
