Off Rwy 24 at Manchester , very quiet day so given direct Otringham and climb , with No speed restriction. Tightened the bank angle and reduced speed to 140kts [ ATP ] . They tried to 'boxxxx' me for coming off min noise route , which were designed at 210-250 kts . They had forgotten at 140 we'd have a smaller radius of turn . We went up well so less noise , saved fuel , and time as well.
If quiet at LHR , back in the day our rented in 737-300s with all derates out could easily get above FL100 at EPM or Burnham from Westerly departures .
Chevvron , remember full clearances with readback . Never read out as fast as US controllers did , thankfully . When I retired we were getting them on Acars [ data link ] , but the 744s still had NDBs !
