already pointed out that the different flight rotation plans in the us and europe combined with the new ads-b counting method sets european sites back extremely. this is well documented by european ads-b decrease of 50-60% while us decrease was only 25-30%.
now i was thinking about a second thing:
-> a day in fa-stats for all sites worldwide is a day from 0h utc to 24h utc
-> for europe this means the next day begins one hour after midnight and is very similar to the ‘real day’ over here
-> in the us the next day starts middle of the day - varies between east- and west-coast
but what does this mean for ‘aircrafts per day’?
=> in europe when over night there is nearly zero traffic -> nearly zero aircrafts are split in two
=> in the us hundrets of aircrafts count into both days
i’m not 100% shure about this thing at the moment - maybe i overlooked an aspect …
