Then recapping and considering us operating after 1st of may if you have an eobt 10.00Z and an airport taxitime of 10' you will be suspnded at EOBT + Taxitime + 20 = 1030z. Eurocontrol reduced the FAM windows from 30'to 20'in approximately 1 year (or little more) to avoid the situation of Flight/aircraft living in a "limbo"between needing a delay (after 15 minutes of ETOT) and not being suspended. now this period of time is reduced to 5 minutes.
But from Autumn 2019 it will be 15 mins insead of 20 and during winter for example, the taxitime for the runway furthest from the apron is 20 mins, but it's a first I hear about suspension from ETOT and not EOBT. Everything I read said from EOBT (i just looked at an internal announcement that its 20 mins from May and it says EOBT). I also read that a flight must take off 15 mins after EOBT (regardless of that FAM parameter), but don't quote me on that yet, I'll read up again today and paste it here, maybe I misread.
