Why is AAHK/CAD enforcing this now though?
The QC scheme was introduced when there were 230 flights scheduled between 10pm and 7am (defined as “night” in the Integrated Noise Model ) and AA was in danger of busting their agreed noise exposure forecast contour limits.
Given the current circumstances, it seems unlikely those sort of numbers will be resumed for another few years at least.
Apart from a few cargos, what else is there overnight at present?? The QC scheme must be hugely undersubscribed right now surely- what’s the pressure the get rid of a few QC4s when the industry is on its knees??
