It depends on the weather condition and the pilot
controllability...
When there is no gust wind and the pilot got good control over
the helicopter then it can float or stand in the air for longer
time

poles are the plot of the transfer function of a system on the
left side of the origin, in s-plane. zeroes are the right side
plot. poles and zeroes specifies the absolute stability of the
system.. they also gives the observability and controllability of
the system..
