Is 250kts required below 10,000 feet in UK airspace
Was departing Heathrow yesterday and overheard the controller ask a Ryan Air flight what his indicated speed was, he answered 310 kts, the controller told him that he was below FL100 and his speed should have been 250. Does the speed limit of 250 only apply to STARS when required to approaching the slp and on SIDS when specified or is there a blanket 250k speed limit unless authorised by ATC? Our company policy is always 250 below 10 unless required by ATC to fly faster. The FAA is very straight forward about this issue.
