Spent a large part of the (no-fly) afternoon doing just that ffb. The latest 5th edition ANO makes substantive revisions on previous editions - it now seems to almost exclusively refer to non-EASA aircraft. I've assumed S4 ROTA is an exemption to SERA.3215. The sub-text of my question was to query whether 'continue to fly during the day' included continuing to use a (training) aircraft for multiple exercises during daylight hours knowing it's anti-collision lights were u/s. The way the ROTA is written, I've interpreted it as a single flight. Splitting hairs maybe.
