Pages 9 and 19 show that all B737s are QC1 or less & OK for arrival; except for the now largely obsolete -200s (which are more than QC1), all are OK for departure too. Government and military exempt from QC scheme, although they still count towards the monthly 120 per calendar month limit during the night-period. The QC scheme is not a restriction on B737 operation therefore.
Perhaps
asdf1234 using a different QC scheme to the rest of industry?
I take my figures from the EASA list of aircraft approved noise levels, specifically the approach and lateral readings.
