That would be troublesome, because the g in non-accelerated flight (ie. straight and level, steady climb, steady descent) must average exactly1g. Given there will inevitably be times when it is slightly above 1g, also by definition, there must be times when it is similarly below 1g.
How would a helicopter ever level off from a climb or enter a descent if what you claim were true?
Where is it said that teetering heads are not allowed to fly at less than 1g?
