Does anyone know how much weight is given to experience to ATC/CCF and UAS experience in cadet programmes as a whole?
There's plenty of people who get into BA FPP et al. without having done UAS. It certainly helps but if it was a requirement the airlines would say so. I guess the main benefit would be proving your motivation and giving you examples for the "HR" type questions. Gliding/PPL will certainly suffice for the motivation aspect and any work/life experience can be just as good when it comes to giving skill examples.
In general, I'd say don't waste too much time looking for a "golden bullet" with these schemes. Degrees/PPL/Cadets/loads of work experience are all nice to have but plenty of people get in whilst "missing" one or two of them. If you're well-rounded enough and can prove you've got the aptitude/motivation/experience in other ways then there isn't a problem.
Just my two-cents worth anyway
