A journalist collects and distributes news and other information

Unfortunately in NM’s experience far too many of them fall into the following genre

writing that reflects superficial thought and research, a popular slant, and hurried composition, conceived of as exemplifying topical newspaper or popular magazine writing

So not so long ago a piece appeared in a local rag bemoaning the fact that a reader posted a message on a local airport story, saying an airline could not get the ATC slots for summer flights because it does not have enough staff available to man the planes having made lots of cuts over the winter.

An ATC slot is produced via the CFMU, (thats a big building in Belgium, but thats not important at the moment,) as a function of airspace capacity. Naff all to do with airline staffing. So heres how it works …

Idiots guide to ATC slots.
Its very simple, if you have a room that holds ten idiots, you can’t put eleven idiots in the room. (much as you might like to)
Idiot number eleven has to wait until one or more idiots come out, or the room is made bigger, so the idiot (No11), gets a slot time. This is the time the idiot has to present itself to commence their journey to the room. If there’s only seven idiots in the room, then you can get three further idiots in there without restricting their progress at all, but the fourth idiot and any subsequent idiots will have to wait their turn. If that room is in fact a corridor joining two rooms, then you can only get so many idiots down that corridor at any one time, even if the room at either end has a limitless supply of idiot capacity. Therefore any idiot wishing to pass through the corridor may get a slot time for the corridor, depending on how many idiots wish to use the corridor at any given time. If there is another different corridor, joining the rooms you can send the idiots down those corridors, which may mean that the idiots will not be restricted at all.

So you can see using the above idiots guide, you should be able to see that ATC SLOTS, do not get secured by an airlines schedule, or their staffing levels, they are a tactical daily/hourly response to airspace capacity. But please don’t let inconvenient substance like facts get in the way
