This might seem like an elementary question but it's in reference to the CHINS6 arrival into Boeing Field. I can't seem to find a reference to post the arrival image in this thread but those that are familiar will know what I'm talking about.
On the arrival there is a crossing restriction for turbojets to cross RADDY at 250kts & 12000 feet when landing north. If I remember correctly the Jepp chart says "RADDY at 250kts 12000feet". My interpretation of this statement is that you need to comply with the speed restriction and the controller will issue the altitude restriction.
Other arrivals say something like "EXPECT RADDY at 250kts and 12000 feet" or "CROSS RADDY at 250kts, EXPECT TO CROSS RADDY 12000 feet".
Basically the situation was that we were descending over a Dash 8 on the way in and the controller couldn't give us the altitude restriction. He did not issue a speed restriction at RADDY, I thought we should slow to 250 based on the chart saying "RADDY at 250kts" but the other pilot disagreed. We slowed anyway and the controller didn't say anything.
If I can find a Jepp I'll scan it and post it up.
