WX 301 Exam 1 Questions and
Answers 100% Pass
Why is a direct comparison of station pressures difficult? - ✔✔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 - ✔✔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? - ✔✔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). - ✔✔False
The aneroid barometer at your station reads 27.57"Hg. If the station elevation is 2,000ft,
what is the altimeter setting? - ✔✔29.65"Hg
For the same station as above, what is the altimeter setting if your station pressure is
27.32"Hg? - ✔✔29.38"Hg
At what Pressure Altitude (PA) does 27.32"Hg occur? - ✔✔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)? - ✔✔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? - ✔✔-250 ft MSL
