An increase in temperature, and, to a much lesser degree, humidity will cause an increase in density altitude.
12.
In this configuration the aircraft flew acceptably, but did not climb well on hot days at higher density altitudes.
13.
In hot and humid conditions, the density altitude at a particular location may be significantly higher than the true altitude.
14.
Several factors affect the rate of descent in autorotation : density altitude, gross weight, rotor rotational speed, and forward airspeed.
15.
An aircraft must also take off at a reduced weight in hotter or more humid conditions ( see density altitude ).
16.
Combined graphs allow the pilot to predict aircraft performance for variations in density altitude, weight, and winds all on one chart.
17.
Thus, in hot and humid conditions, the density altitude at a particular location may be significantly higher than the true altitude.
18.
These gas balloons float at a constant density altitude, where the balloon displaces a mass of air equal to its own mass.
19.
Both an increase in temperature, decrease in atmospheric pressure, and, to a much lesser degree, increase in humidity will cause an increase in density altitude.
20.
The specific airspeed is different for each type of helicopter, yet certain factors ( density altitude, wind ) affect all configurations in the same manner.
