ATC PHRASE

What does it mean when atc tells the crew to delete speed restrictions. I assume it means that crew can fly their own speed schedule.

Pretty much, the controller may have told them to maintain a specific speed and the controller is simply telling them they can disregard that instruction.

I suppose it could also be used in a situation such as the 250kt speed limit in class B airspace, saying they can exceed that, don't hear that much but it would just depend on the context of the instruction.

I believe what you need to know is covered in these websites, it's a lot of reading, maybe a member who is a pilot will jump in here.

Specifically, it means a pilot can disregard a speed restriction indicated on a STAR or other instrument procedure. It does not give a pilot permission to exceed the 250 ias restriction below 10,000 MSL.

If a controller had issued a speed restriction in order to achieve separation and no longer requires the pilot to maintain that speed, the proper phraseology is "resume normal speed".

I have heard that. Yesterday, while delivering close to KSLC I heard the delete speed. I am not sure if it was approch or departure.

I was going to say that you must have been near SLC. That is the only airport in the nation I have flown into that uses that phraseology. If you can get a copy of the SIDs/STARs used at SLC, most of them (if not all) have multiple crossing restrictions that have either an altitude restriction (at xx ft, at or below xx, or at or above xx), a speed restriction (usually at xxx kts) or both. When there is no need to slow an aircraft down to the published speeds, or have them fly faster than they typically would to comply with the restrictions, ATC will issue that clearance.

Believe me, that phraseology is used all over the NAS. I heard it issued more than a few times by controllers in my area at ZME when they were working arrivals last Friday.
