Let’s say you get the 48hr weekend PN for Sat+Sun, and you get there on the Sat and it becomes obvious that you can’t go back on Sun due to wx.
Let’s also assume you a) can’t speak French and b) do not have unpublished police phone numbers / the police do not answer the phone.
Has anyone just flown back out of there?
Obviously, 48hr or even 24hr PN is ridiculous, operationally…
Quite likely the airport atc might not give you a departure clearance.
In the circumstance described, and assuming you don’t still have 48 hours to give the new notice, then I’d contact the airport tower. They will speak English and probably be able to contact customs on your behalf.
If that doesn’t work out, then I’d simply send a note by whatever means you send the notice originally, advising that your departure had been delayed and advised of the new date and time and give them your contact details and fly at that time.
I don’t think it’s reasonable to just fly the day after your notice without letting customs know of the delay.
LeTouquet is the ultimate backup plan, no PNR between 0900LT-1900LT (also Calais with 2h PNR)
Then you have Kortrijk (EBKT) no PNR between 0600LT-2200LT, just GENDEC on website before departure
I am not aware of other legal work around this, especially on weekends? there are not that many airports (French, German, Dutch, Swiss, Spanish) where I can turn up out of the blue and ask for flight to UK without notice or handling? like LeTouquet or Kortrijk? (well there is Vatry, Carcassone that are rare exceptions like LeBourget for “existing 800€ clients” and then there is Nantes between 1000LT-1700LT, the aeroclub take visiting aircraft without notice or short notice and police will come to their parking for formalities)
there are not that many airports (French, German, Dutch) where I can turn up out of the blue and ask for flight to UK without any notice or short notice
All German major and mid-size airports. No PPR whatsoever for landing / parking and also no PN for extra-Schengen flights.
What I had in mind is departing earlier, but a delay is in the same category (except that a 1 day delay may enable 24hr PN compliance, obviously).
Going back via LFAT is a long way round but a legally valid option. Going back via Germany is impractical.
I was wondering if anyone had actual experience of getting a short-notice approval, or just flying out. I doubt ATC would connect with the police.
I got it once at La Rochelle and they did it (they “had” to turn up to stamp my passport) but not too happily, and it was possibly only because I had their “secret” number, which is found on a notice on the wall of the hut where you pay landing fees. After the “GA gate and no checks” option was posted here a year or so ago, the police there are very much more active; I reckon somebody reading EuroGA told them.
I had two experience of leaving early.
Once in deauville, I asked the agent on arrival if I could leave earlier in the afternoon on a Sunday because I was worried about the weather and she told me it was fine as she would be here all day due to a charter flight. She was there and remembered me and was very pleasant.
Another time another airport, the reply to the PN was that they would not come to check me and the information I had sent was enough (EU passport) and at the end I departed different time than initially booked (but same day)
Though neither case are something you can plan or prepare for, just luck on these days. The other cases I had to changed due weather I flew detour to le Touquet.
LaRochelle has airliners to UK and extra-Schengen (same for Bergerac, Rodez, Carcassone, Poitiers…). They have C+I on duty for these flights and gets easy to waive notice periods. Outside these slots, one can always ask to see if they can turn up?
In airports without scheduled flights, it’s usually not possible to arrange or even talk to anyone during weekend. On weekdays, it’s different they are flexible, however, with pob requiring stamps, they either show up with grumpy face or ask to go elsewhere
One can’t plan based on this (well unless they ask on arrival what to do for change of plan?) and the answer depends on who, when, where, how…
Also want to mention though I never actually did it; as the one day I was planning to I cancelled all together as weather dreadful
But Calais as a 2h pn including on weekend. While it’s very close to le touquet, it has east/west runway and can be a good last minute alternative to le touquet when cross wind too high.
On that Sunday I considered it, I called them to confirm it was fine with 2h PN Sunday, which they did, but ultimately I didn’t go as mentioned.
I sent this to Deauville
Do I also have the option of a day trip on 15th, if the weather is too bad to return on the 16th?
It would be impossible to do the 48hr PN, obviously.
and got this back
If there is a change, please send an email and we will transfer to the customs.
So, a non-answer. The wx clearly needs to be perfect 
Isn’t this hobby of ours completely mad sometimes? A flight EGKA-LDLO (700nm+) is vastly simpler than a flight EGKA-LFRG (~70nm). And it shows… if AOPA DE says “let’s go to LDLO” about 50 planes turn up, flying right across the Alps. And LFRG just gets a few locals.
I have worked around this issue at a few French airports airports by filing notifications for both days and/or multiple timeslots and explained that this was due to weather uncertainty.
