Answer :
Final answer:
The pressure and density altitudes cannot be determined from the provided information, which includes an outside pressure of 1.5089 N/m^2 and a temperature of 220K, due to the lack of standard atmospheric conditions for comparison.
Explanation:
To determine whether the provided values of pressure and temperature correspond to pressure altitude or density altitude, one must understand the definitions of these terms. Pressure altitude is the height above the standard datum plane when atmospheric pressure is measured. Density altitude refers to the altitude relative to the standard atmosphere conditions at which the air density would be equal to the observed air density.
The question asks for the pressure and density altitudes given an outside pressure of 1.5089 N/m2 and a temperature of 220K. Neither of these values, however, directly provide pressure altitude or density altitude without additional calculations and information such as the standard atmospheric pressure and temperature, and the altitude at which these conditions are observed.
Without the additional information needed to calculate pressure and density altitudes, or a provided set of standard conditions to compare to, one cannot determine the correct altitudes. Therefore, the most appropriate answer to the student's question is (c) The values cannot be determined.
