Sabena boy, there are many pilots out there who have to come back to 250 or less when below FL100.
E145 comes back to 240
Easyjet will always come back to 250 unless INSTRUCTED to maintain high speed
There are countless others who will also do the same.
As for asking if there is any speed restriction, 9 times out of 10 they want to keep high speed, othere times they might want to reduce below 250 for reasons unknown to ATC, I've been caught out in the past with a 752 reducing to a ridiculously slow speed with about 35 miles from toughdown, completely screwed up my sequencing plan, but because I didn't stipulate a speed I can't complain.
