27
What is Pressure Altitude equation?
PA = Airfield Elevation + 30(1013-QNH)
28
Determine PA
```
Elevation = 120ft
QNH = 1005hPa
```
PA = 120ft + 30x(1013-1005) = 120ft + 30x8
PA = 120ft + 240ft = 360ft
29
Determine PA
```
Elevation = 240ft
QNH = 993hPa
```
PA = 240ft + 30x(1013-993) = 240ft + 30x20
PA = 240ft + 600ft = 840ft
30
Determine PA
```
Elevation = 60ft
QNH = 1038hPa
```
PA = 60ft + 30x(1013-1038) = 60ft + 30x(-25)
PA = 60ft + (-750)ft = -690ft
31

32

33
What is Density Altitude equation?
DA = PA + 120(Outside Air Temp - ISA Temp @ PA)
34
Determine DA
PA = 2000ft
Outside Air Temp = 10C
ISA Temp @ PA = 15C-(2x2[1,000fts]) = 15- 4 = +11C
```
DA = 2000ft +120(10 - 11) = 2000ft + (-120)ft
DA = 1880ft
```
35
Determine DA
PA = 4100ft
Outside Air Temp = 20C
ISA Temp @ PA = 15C-(2x4.1[1,000fts]) = 15- 8.2 = +6.8C
```
DA = 4100ft +120(20 - 6.8) = 4100ft + 1584ft
DA = 5684ft
```
36
Determine DA
PA = 4100ft
Outside Air Temp = -0.5C
ISA Temp @ PA = 15C-(2x4.1[1,000fts]) = 15- 8.2 = +6.8C
```
DA = 4100ft +120(-0.5 - 6.8) = 4100ft + (-876)ft
DA = 3224ft
```
37
Determine DA
PA = 800ft
Outside Air Temp = 5C
ISA Temp @ PA = 15C-(2x0.8[1,000fts]) = 15- 1.6 = +13.4C
```
DA = 800ft +120(5 - 13.4) = 800ft + (-1008)ft
DA = -208ft
