Actually it's civil twilight, which is about half hour the dark side of
sun thresholding, depending on latitude.



The FAA uses different definitions of "night" in different situations. For
purposes of currency "night" is the period beginning 1 hour after sunset and
ending 1 hour before sunrise.



Yes, but this isn't a currency flight, this is a training flight for
logging night flight time, so I think the civil twilight definition is
appropriate.
