One thing I noticed a few weeks ago when trying to write up my UAS hours was that the little orange UAS logbooks (RAF F414 [UAS]) do not have space to record actual time of departure and actual time of arrival, only durations of sorties and creditable hours. Actual times are required, as I understand it, should you wish to gain any sort of civy license when the CAA/FCL/whoever have a look at your logbook. So, in order to save yourself a rather long and tedious trawl through auth sheets in a year or two, record this information somewhere.
Perhaps a civvy logbook would be the place? But then you've got the whole taxi-time palaver as well - I'll leave that for someone else yo go through.. as I don't think I'm quite clear on it yet!
As for the flying available to students - I left in July, and the biggest hindrance to flying was those pesky EFT full-timers stealing (breaking?) all the aircraft!
