I get nothing but conflicting viewpoints on this one...
Look at the KLYNK arrival into DTW... (

Reference the 'descend via mach until 280' note...
Let's say you are just about to pass KOZAR and you are at fl240 indicating 300kts (your cruise speed).
My opinion is that you slow to 280 before passing KOZAR.. Some people agree with me, others say "we aren't descending yet and we don't have a published speed until EEEZI." Either way my viewpoint is more conservative. I know the intent of the note is to intercept 280 from the mach number when you were at a higher cruise altitude and descending.. But what about this scenario when you are starting out lower and faster (indicated)? Also would like to see a reference to a rule or guidance in writing if you have a strong opinion.
Cheers
