density altitude การใช้

• These speeds, in true airspeed terms, vary considerably depending upon density altitude.
• Field elevation is, and density altitude problems can be encountered in the summer.
• High temperatures in summer can result in high density altitude conditions.
• Contributing to the accident were the downdrafts, high density altitude, and mountainous terrain ."
• Aviators gauge air density by calculating the density altitude.
• The Integrator was test flown at lower density altitudes.
• Density altitude can exceed in summer months.
• In aviation, the density altitude is used to assess the aircraft's aerodynamic performance under certain weather conditions.
• It features two Lycoming TO-360-E1A6D engines, which offer a significant improvement in performance at high density altitude.
• At low density altitude and light loading, best performance is achieved from a slight decrease in normal airspeed.
• An increase in temperature, and, to a much lesser degree, humidity will cause an increase in density altitude.
• In this configuration the aircraft flew acceptably, but did not climb well on hot days at higher density altitudes.
• In hot and humid conditions, the density altitude at a particular location may be significantly higher than the true altitude.
• Several factors affect the rate of descent in autorotation : density altitude, gross weight, rotor rotational speed, and forward airspeed.
• An aircraft must also take off at a reduced weight in hotter or more humid conditions ( see density altitude ).
• Combined graphs allow the pilot to predict aircraft performance for variations in density altitude, weight, and winds all on one chart.
• Thus, in hot and humid conditions, the density altitude at a particular location may be significantly higher than the true altitude.
• These gas balloons float at a constant density altitude, where the balloon displaces a mass of air equal to its own mass.
• 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.
• The specific airspeed is different for each type of helicopter, yet certain factors ( density altitude, wind ) affect all configurations in the same manner.
