Arr I don't know the exact details as I'm not an instructor, your logbook is a legal document (make sure it's signed). As far as we seem to know so far is that all your documents will still be in the HFS building, jock mentioned that the local PPL examiner will be the person in charge of what happens next to them. I'm sure he's getting alot of requests as this is typed hopefully there will be a way of administering the student records so that people can get all their exam certs and hours logged counting towards the rest of their ppl course which can be finished with another training provider.
Sit tight for a few more days and more actually useful information will become clear.
Jock, you're right I had a good read through the ICO website, it's hardly clear but sadly I'm not protected by Data Protection. I just do not want HAC to get my student records, I don't trust what they might do. What can I do?
