-how would a high density altitude affect performance of a helicopter?
performance would be good due to the high value of the air density
performance May improve or be decrease the density altitude has to be
corrected for non-standard temperature engine performance would increase
but rotor performance of d3s performance would be decreased due to low
value of the air density density altitude is not as important a factory
performance as temperature and humidity - -
