European flight plans
Good day,
I've been trying to find an answer to this for some time and wasn't very lucky neither on the EuroControl website nor on the ATC section of the jepp manual, perhaps the local experts can shed some light...
I'm needing to know how long ATC flight plans are valid after the EOBT, 60 min? 45 min? 15 min? What are the deadlines for making a DLA/CHG? And off course, with how much advance, in regards to the planned EOBT, the plan has to be filled?
I understand that some countries have differente policies regarding this and as I mentioned, this is not easily found.
Well, maybe I'm looking on the wrong places
Thanks for any inputs!
Best regards,
Salz

flight plans
Ive had instances where id forget to delay the flight plan and putting in a DLA message still worked even after 1 hour after the filed take off time. But i was alway taught it was valid for 30 minutes. Dont know about the CHG. I believe with Eurocontrol you can file a flight plan 4 days in advance.

Thanks so far folks,
Indeed 30' rings a bell here, but I still think there are at least two contries where it's only 15'
In fact, one can file a flight plan with 5 days in advance with Eurocontrol
Cheers

Slots
If you have been issued with a CTOT (restricted slot) then you have a -5/+10 minutes window. You also have to take into consideration the taxi allocation.
For example if you have been issued with a 12:10Z CTOT and at an airport with a 15 minute taxi time allocation, your window to request engine start is between 11:50Z & 12:05Z.
With an ETOT (unrestricted slot) I believe its technically -15/+15 minutes, however I beleive at several locations they go on -30/+30 minutes.

Filing in advance
With regards to how far in advance you can file flight plans with EuroControl it could well be 4 or 5 days, however a lot can change in those few days.
Aside from the fact that you won't have any valid weather forecasts for accurate alternate selection, there could be any number of NOTAM's or airway closures which could result in FPL suspension on the day of operation.

Flight Plans in the IFPS zone (Europe) require a DLA to be put in when the aircraft is running more than 15 minutes later than it's EOBT.
HOWEVER - Don't (as I've seen done) DLA the plan if the aircraft is running slightly late and is on a CTOT (even if it looks like it'll just miss its -5/+10 minute window there). Liaise with ATC first - that 5 minute delay could change into an hour and we might be doing something in the background to get your flight away.
If you want to depart more than 15 minutes earlier you're meant to cancel and re-file. The problem with this is that your departure clearance is actually issued (from the UK centres anyyway) 20 minutes before EOBT. Cancelling means suspending the clearance until the new plan is in the system. So, from a practical point of view, don't do the above unless you want to go more than 30 minutes earlier than the original EOBT.
Flight Plans can be filed up to a week in advance (used to be 96 hours)

CM,
I was always under the impression that if the flight was ready to go early, a Ready Message would suffice, rather than go through cancelling your plan and re-filing, which could on a bad day in effect delay your flight by becoming subject to a CTOT.

Ready messages are there to try and bring forward a CTOT - nothing to do with the FPL EOBT itself. You cannot submit a Ready message if there is no CTOT and the flight is not subject to flow regulation.

This thread just sums it all up…
We need a JAR flight dispatch licence urgently to educate these sorts of things. If the basics are misunderstood then how is the whole industry meant to function. Yes the answers are on the CFMU site but without training how are people to know what to look for..

Actually the "lifetime" of FPLs in IFPS is EOBT+Total EET+3 hours.
E.g. a flight from Barcelona to Manchester, with a EOBT at 10:00, flight time 02:01, will close in IFPS at 15:01.
That means that technically the AO can send a DLA/CHG well past the EOBT, which will be accepted and distributed.
So, in principle ATC systems must be able to accept updates well past the 30 min nr.
Still, as mentioned before ,AO's have to update their EOBT if delaying more than 15 min.
Failure to do so, in areas where Flight Activation Monitoring is enabled, will entail an FLS at EOBT+30 min if nor reported airborne.

It depends from where you leave. You get a FLS after: IOBT + TAXI + 30 minutes. That means that in EDDM you will get a FLS at IOBT + 50. Normally we update earlyier but should we forget to do....
