This summer is going to be worst ever in Europe for delays (so we’re told), which means if you’re going there you’re going to get a nasty CTOT sooner rather than later.
So rather than writing a long and helpful blog post to help you navigate the slot rules, instead we’ve put together a vacuous and infantile story book.
But, it might still help a little to figure out how NMOC (the artists formerly known as CFMU) at Eurocontrol works, how to deal with a bad slot, requesting improvement, how and when to file, and when you should or should not contact NMOC for help.
Once you’ve enjoyed (or not) storytime, be sure to scroll down for some more “adult” links to the in-depth material đ

If you prefer, try this “Book” version …
So, onto the adult version… Eurocontrol NMOC have published a really useful guide to slots this month, for the Summer of 2022. Download that here as a PDF (31 pages)
For the full bible, you want the IFPS users manual, and the ATCFM operations manual.

It’s been a great few days on a sun-soaked Mediterranean island. Your passengers are onboard, you are about to close the door, and then you get told your Calculated Take Off Time (CTOT) is an hour from now! Sound familiar? You’re not alone! ?
“Data from Eurocontrol shows that in the first half of 2018, Air Traffic Management (ATM) delays more than doubled to 47,000 minutes per day, 133% more than in the same period last year. Most of these delays are caused by staffing and capacity shortages as well as other causes such as weather delays and disruptive events such as strikes. The average delay for flights delayed by air traffic control limitations reached 20 minutes in July, with the longest delay reaching 337 minutes.”
