To determine the approximate density altitude, you begin with the pressure altitude, which in this case is 6,000 feet. The next step is to adjust this altitude based on the current temperature, as density altitude is affected by deviations from standard temperature.

In standard atmospheric conditions, the temperature at 6,000 feet is typically around +10 °C. However, the stated true air temperature is +25 °C, which is 15 °C above the standard temperature. This increase in temperature results in a decrease in air density, which is reflected in a rise in density altitude.

The adjustment for increasing temperature is roughly 120 feet of density altitude for each degree Celsius above standard temperature at that altitude. Since we have a deviation of approximately 15°C, this leads to an increase in density altitude of around 1,800 feet (15°C x 120 feet/°C).

Therefore, adding this to the pressure altitude gives us:

6,000 ft (pressure altitude) + 1,800 ft (adjustment for temperature) = 7,800 ft.

However, the density altitude is typically not stated as such; the adjustment proceeds through a more refined calculation for precision. When we adjust accordingly for standard atmospheric conditions and compare
