"Speed restrictions removed"
Was talking about this with a few captains I've been flying with regarding the interpretation of the phrase by ATC "speed restrictions removed" on departure. Particularly pertaining to outside of the US, for example departing out of HKG. Most SIDs will have speed restriction at a few waypoints (max 220kts until waypoint X, max 240kts until waypoint Y) and also a note on the plan view "max speed 250kias below 10,000."
My question is, if you're flying a heavy aircraft that requires, say, 265kts for a clean maneuvering speed and ATC tells you that "speed restrictions are removed" can you now
1-cancel any waypoint speed restrictions along the SID (220 to X, 240 to Y) but still limited to 250kts
2-accelerate above 250kts as required to clean up and climb
3-disregard any speed restrictions and accelerate to a cruise climb speed, say 280-320kts
I know in some places the terms "high-speed climb approved" and "speed restrictions removed" are used interchangeably, in others they have different meanings. People I've flown with seem to interpret this phraseology different, figured I'd see what everyone's take on it was.
