Question

1. if the outside air temperature (oat) at a given altitude is warmer than standard, the density altitude is

○ a. equal to pressure altitude.
○ b. lower than pressure altitude.
○ c. higher than pressure altitude.

Explanation:

Density altitude is pressure altitude corrected for non - standard temperature. When the outside air temperature (OAT) is warmer than standard, the air is less dense. Since density altitude is calculated based on temperature and pressure, a warmer - than - standard temperature (while pressure altitude remains the same) will cause the density altitude to be higher. For example, in the formula for density altitude (which is more complex and involves the ideal gas law concepts), temperature has a direct impact on density. Higher temperature (above standard) leads to lower air density, and density altitude (which is an altitude representing the density of the air) will be higher than the pressure altitude (which is based on pressure alone).

Answer:

C. higher than pressure altitude.
