CORRECT Answers
Why is a direct comparison of station pressures difficult? - CORRECT ANSWER✔✔-
Weather stations are often at different altitudes
You're flying in Europe and the altimeter setting is reported as 988mb. What is the altimeter
setting in inches Hg? Recall 1013.2mb ~ 29.92 "Hg - CORRECT ANSWER✔✔- 29.17"Hg
Altimeter setting and sea level pressure (SLP) both provide estimates of the pressure at a
station if that station were lowered all the way to mean sea level? - CORRECT
ANSWER✔✔- True
Altimeter setting and sea level pressure (SLP) are calculated the same way and provide the
same value, just in different units (inches mercury versus millibars). - CORRECT
ANSWER✔✔- False
The aneroid barometer at your station reads 27.57"Hg. If the station elevation is 2,000ft, what
is the altimeter setting? - CORRECT ANSWER✔✔- 29.65"Hg
For the same station as above, what is the altimeter setting if your station pressure is
27.32"Hg? - CORRECT ANSWER✔✔- 29.38"Hg
At what Pressure Altitude (PA) does 27.32"Hg occur? - CORRECT ANSWER✔✔- 2,500 ft
MSL
If your station elevation is 1,250ft MSL and your altimeter setting is 30.19"Hg, what is the
pressure altitude at the station (i.e., the surface PA)? - CORRECT ANSWER✔✔- 1000 ft
MSL
What is the PA conversion factor for question 8, i.e., how much height must you add to the
station elevation to get the surface PA? - CORRECT ANSWER✔✔- -250 ft MSL
