I think it is wrong to inflict noise on people late at night.
Aircraft (except Queenairs
) are not noise.
I live on the flight path at YPPH where there is no curfew and though we get movements right through the night, it isn't really an issue.
In fact, if it were more consistent, we would probably notice it even less.
Only other problem is listening to the SFC BE58s "losing" an engine at the MM and the resulting howl of the "good engine" getting caned doing the missed app. Painful
