I don't expect any particular rate, but I would anticipate at least 500ft/min always, if I need to know the current VSI I'll ask for it, if I need improvement on that I'll ask for it.
"standard rate", oh my brain hurts,
The phrase “STANDARD RATE”, when included in a clearance, specifies a rate of climb or descent of not less than 500FT per minute, except that the last 1,000FT to an assigned level must be made at 500FT per minute.
In the case of a step-climb or descent, the specified rate will be applicable to all level clearances issued in the course of the step climb or descent. If unable to comply with the prescribed rate, the pilot in command must advise ATC.
But hey that may not be a 'standard thing' just down here in sleepy hollow.
