Hi everyone,
For what it's worth I go with the above, i.e. five take-offs and landings to full stops, logged as one flight but with the remarks column entered with some appropriate description of what was done. I've never had any trouble with the CAA accepting this for my students' night qual. applications. Just one thing though, and without wishing to start the usual bun fight (see multi-engine instruction dangers!), I'm not a great fan of the stop and go (personally). I get my students to backtrack to the threshold after each landing - may as well use all the runway if you've got it and I find they usually need the time anyway. However, I appreciate that this may not always be practical, or necessary, depending upon where you fly from.
Anyway, safe flying, good instructing and a happy new year to everyone in the air.
Regards, GT.
