Given the following, what is the density altitude?

Pressure altitude: 5500 feet
Static Air Temperature SAT: +33°C

  • A
    6500 feet
  • B
    9000 feet
  • C
    5800 feet
  • D
    6000 feet
Calculation of Density altitude with Pressure altitude and Temperature

Density altitude is not related with the altitude of the aircraft, it is a measure used for aircraft performance.
Density altitude is the altitude in the ISA atmosphere with corresponds to the density which you are experiencing in the current ambient atmosphere.
Density Altitude = Pressure Altitude + (ISA DEV. x 120)

ISA temp. = 15 - 2 x 5.5 = 4ºC
ISA dev. = 29º C
Density Altitude = 5500 + (29 x 120) = 8980 ft
