Density Altitude (Pressure Altitiude) Worksheet

8-47
(Refer to figure 8 on page 8-30)

Determine the pressure altitude with an indicated altitude of 1,380 feet MSL with an altimeter setting of 28.22 at standard temperature.

a. 3,010 feet MSL
b. 2,991 feet MSL
c. 2,913 feet MSL


A    28.22
B    * Altimeter 28.20   factor 1,630     97 Feet
C    * Altimeter  28.30  factor 1,533

* pressure altitude conversion chart

A - B   =  28.22 - 28.20   = .02
C - B   =  28.30 - 28.20    = .10


97/.1   x .02    = 19.4 feet

Pressure Altitude Conversion Factor  = 1,630  - 19.4 feet  = 1611

Pressure Altitude  = 1, 611 + 1,380 feet MSL = 2,991 feet MSL

Density Altitude   =  Pressure altitude of 2,991 feet MSL to 59 deg intersection on chart is 3600 Feet

Note: 59 deg is standard temperature
