7 Speed Limit
(a) A speed limitation of 250 kt applies to all departures following SIDs whilst flying below FL 100 unless previously removed
by ATC. ATC will endeavour to remove the speed limitation as soon as possible and will use the phrase 'No speed
restriction'. The phrase must not be interpreted as relieving the pilot of his responsibility for the observance of any noise
abatement procedures which may include a speed/power limitation.
