It then depends on the instructor/staff cadets being at the squadron, on those nights.
If you are going have older cadets doing things at least do the courtesy of getting them ‘planned in’ and not just there to do filler / last minute things.
How do you fix camps and DofE expeds into the plan? We generally work no more than 3 or 4 months in advance for DofE so that the amount of staff needed can provisionally commit to the dates. I know Gold are done well in advance, but the other two aren’t, or not with us. Camps affect so few cadets now as not to be worthy of mention. Four to six is not like the old days of 15-20 places per squadron, but then that was easy to deal with and just stand down. Now it’s no more of an embuggerance than people going on holiday.
Similarly Wing events, for us at any rate used to be announced well in advance but now not so. I would suggest the only things you can definitely put on a programme are RAFA Wings Appeal if you are involved and Poppy collecting and Remembrance parades, and national holidays. Everything else is fluid.
I would suggest however looking at borough and school websites to see when their holidays and other things are on school websites calendar/events page or parents letters to ensure that you plan in such a way to be sympathetic to the cadet’s availability and you don’t just crash along and then find the attendances aren’t as expected due to something happening at school.
As TO not really your remit to plan, but ensure the adult staff get sufficient time off to do family things especially at Christmas. We used to parade right up the last possible moment at Christmas and back straight in just after New Year, but for the last 6/7 years we have stood down with a clear week before Christmas and return in the second week of January. The last night of the year is bowling and pizza. I was finding that people went out with work 2 or 3 weeks before Christmas and invariably clashed with parade nights, being the cheaper nights of the week, so I felt it better to remove any concern about ATC. I’ve had no staff, parents or cadets complain.
