What occurs to density altitude with a temperature increase from 30 to 50 degrees F, given a constant pressure altitude of 3,000 feet MSL?

• A. 1,000-foot decrease
• B. 1,100-foot increase
• C. 1,300-foot increase
• D. 1,500-foot decrease

Answer: (C)

To determine the effect of a temperature increase on density altitude, we need to understand the relationship between temperature, pressure altitude, and density altitude. Density altitude is the altitude at which the air density is equal to that of a standard atmosphere at a given pressure altitude. When the temperature increases, the air becomes less dense, which causes the density altitude to increase. At a pressure altitude of 3,000 feet MSL (Mean Sea Level), an increase in temperature from 30 to 50 degrees Fahrenheit (a 20-degree increase) causes a substantial decrease in air density. Since density altitude is influenced by temperature fluctuations—warmer air is less dense—the increase in temperature directly leads to an increase in density altitude. The general rule of thumb for calculating the change in density altitude due to temperature is that for every 1 degree Fahrenheit above standard temperature, the density altitude increases by approximately 120 feet. At a pressure altitude of 3,000 feet, the standard temperature is around 27 degrees F (standard atmosphere). With a temperature rise from 30 to 50 degrees F, we surpass the standard temperature significantly. Calculating that 20-degree increase, you would estimate a density altitude increase of roughly 2,400 feet (20 degrees x
