I have a considerable amount of UK (and European) GA flying around, all individual paints, with a layer of AI beneath that for generics - to get traffic levels more realistic, and can relatively easily create plans, but it still takes time and resources. Since I don't use the DFAI package and have stuck with FS9, these won't be made for my setup anyway.
It is likely that you would need to set up the late Don Grovestine's AIFP and create plans using that software. I contacted Don within the last year of his life (he died in 2022, August 3) and he passed along some useful info to me for my own planner. I used his software to sanity check the output from the tool I created.
https://www.owlsnest.eu/donuser.phpTo use Don's AIFP you'd need information about the aircraft's cruising speed, and research its base (unless Danny has that in the CFG entry's description field) and ideally find out where these things generally operate to, as well as how and where they will operate circuit training. Often school aircraft fly this way and only visit two or three other airfields in a typical week, unless a qualified member rents one of the training fleet.
You may well be aware that in the UK, school aircraft stay close to home and rarely venture more than 100 nm from base, club aircraft might make the occasional long trip. I've rented and flown to the north of the country from Kent, in an aircraft that seldom ventured more than 60 miles from base (it was effectively re-based in EGCC for 3 days in the late 80s!). So, it happens.
You might want to give Don's software a try. If the aircraft speeds are correct, that program gives you an arrival time at the airport you select for a visit, and you only need to decide how long it will sit there, or whether it performs TNGs etc. One tip is that if you decide to do this, an aircraft arriving at a place to perform TNGs will not land there if you make the departure time within about 4 minutes of arrival from the last TNG. So, you could have a training aircraft fly to Blackpool for an hour of circuits and then return, without landing, to base.
Otherwise you will need to find someone that uses your sim, or one close to it, is interested in AI traffic, has the time and inclination to make AI plans, and probably also uses the DFAI package. That's a very small demographic!
