Keeping IR instructing privileges
CAP 804 states that when revalidating your FI rating, if you are also revalidating your extension to instruct for the IR then you need to have done 10 hours instrument instructing in the 12 months leading up to the renewal.
It doesn't say what you can do if you haven't got these 10 hours. Would it be a full course, or just going to an ATO for them to do some "training as required" before the flight check?
