I thought all loggers just started again after a momentary power loss,
and continued the same flight file. It sounds like yours isn't behaving
properly, or are some brands a bit touchy?

There are some earlier approved flight recorder designs that will start
a new flight data file if the 12V power supply is interrupted
momentarily. The specifications were then changed to eliminate this
behavior from newer designs...
