I would assume that (if the speed crossing ahead is CROSS at and not EXPECT to cross at ????) you can speed up to your normal cruising / descend speed for now and than slow down in order to make the speed restriction (to play it safe), however, I would probably ask ATC if they still want me to cross the FIX at the crossing restriction speed.

The speed restrictions are hard crossings not "expect". ATC is busy and you can't get a word in to query them. The controller doesn't like to repeat himself anyway since he already just said "resume normal speed". What is he expecting you to do? Saying you will make the speed restriction "to play it safe" is not an acceptable answer.
 
He is expecting you to stay with the charted arrival unless he says, "Resume normal speed and delete the speed restriction @ xyz"
 
Pertaining to RNAV STARS....

As for the "AT XXX KIAS" restriction, I feel that it is no different from "CROSS AT 11000"...you cannot, nor do you need to comply with the altitude unless allowed by ATC, as in a "Descend Via" clearance. The other times that the controller specifically assigns the altitude to cross the fix at, they seem to also include the speed.

I wholly agree that it feels a bit strange, and I often ask about the speed if it's not clear.

If this sounds wrong, please cite the reference.

Perhaps a trip over to the ATC Forum is in order..

EXPECT clearance to cross at 250kt and 10,000.

Therefore I would resume normal speed until I had to go below 10,000 MSL if there was an EXPECT or I would resume normal speed, and than slow to meet the restriction if it states CROSS AT 250kts. I'm not saying it's correct, but that is what I would do.

It's strange and confusing but you still must comply with the hard speed restrictions unless told otherwise. I'll query the controller in the hope that they're let up keep our speed up.

EXPECT clearance to cross at 250kt and 10,000.

"Expect" speeds is a different matter. My example was about the hard speed crossing restrictions. Lets assume all the crossings on an arrival are "cross at" and the controller says "resume normal speed".
 
Now the confusion of what "resume normal speed" means took another turn. These two statements seem conflicting.

The ATC manual says;

An instruction to "resume normal speed" does not delete speed restrictions that are applicable to published procedures of upcoming segments of flight, unless specifically stated by ATC. This does not relieve the pilot of those speed restrictions which are applicable to 14 CFR Section 91.117.

An FAA document that can be viewed here (http://www.faa.gov/other_visit/avia...afety/info/all_infos/media/2007/info07011.pdf) says;

The phraseology “resume normal speed” does not cancel published speed constraints; rather, per Air Traffic Order 7110.65, Air Traffic Control, it cancels speed constraints previously issued by ATC and returns the aircraft to the published speed for the procedure.

Note the highlighted parts of both statements. They sound different to me as what you are suppose to do.
 
Why is everyone making this seem difficult? There is no grey area. If established on an arrival and given a speed (maintain, at or above, slow to), regardless of what is published, you adhere to that assignment until told otherwise. If given "resume normal speed", that means follow pulished speed restrictions (if applicable) or clacker if none apply. "Expect to cross at" speed means clacker all the way until ATC assigns you a speed or crossing 10k feet.

Here's one for you all that confuses many pilots. You're on an arrival and ATC had previously issued a speed to maintain. They then tell you to resume "normal" speed. You're still on the arrival with speed crossings ahead. What does "resume normal speed" mean?

whatever speed you want. 290....300....320... whatever. Hence normal speed.

just cross that fix on the arrival at whatever speed is printed on the arrival. HOWEVER, if it says expect speed 250 and if ATC did not assign a speed to you at the fix, then its still normal speed.
 
If I may drift the thread a tad, what about altitude restrictions on SIDs, like those in SLC? When there are published crossing restrictions for the climb and ATC issues a "climb and maintain" clearance, does that cancel all intermediate crossing restrictions? I'm more interested in the location of the answer vice the answer itself. (And for what it's worth, SLC ATC often seems peeved when our pilots ask for clarification.)

When ATC gives you a "climb and maintain" instruction, that negates all crossing restrictions on the SID as far as altitudes are concerned. From the ATC Handbook it says;

Restating previously issued altitude to “maintain” is an amended clearance. If altitude to “maintain” is changed or restated, whether prior to departure or while airborne, and previously issued altitude restrictions are omitted, altitude restrictions are canceled, including SID/FMSP/STAR altitude restrictions if any.

If speed is charted--meet the speed requirement.

Giving relief or amending altitude does not change speed limit unless specifically given speed relief.

The speed relief clearance would sound something like "fly normal speed (or some other assigned speed) UNTIL FURTHER ADVISED." If the "UNTIL FURTHER ADVISED" is not given, then you are expected to comply with charted speeds." However, "Expect" is not a clearance either in altitude or speed, until a further clearance is assigned.
