WX 301 Test 1 / Comprehensive Study Guide
Complete Questions and Correct Detailed Answers
Explain the difference between altimeter setting and "actual" SLP -
...(ANSWERS)....Altimeter Setting is the station pressure reduced to sea-level using
the standard atmosphere While SLP accounts for a non standard temp.
Identify the 5 types of altitude commonly used in general aviation (i.e., true
altitude, indicated altitude), and know the difference between each -
...(ANSWERS)....True altitude - Your height above mean sea level
Absolute altitude - Your height above the ground
Pressure altitude - Your height above the standard
Mean SLP surface of 29.921″Hg
Density altitude - Pressure altitude corrected for
non-standard temperatures
Indicated altitude - The altitude displayed on your altimeter. Only the same as
true altitude under standard conditions (assuming a calibrated altimeter)
List the three most common errors in altimeter readings and know which error
the altimeter setting can correct for - ...(ANSWERS)....Sea level pressure (SLP)
different from 1013.25 mb (29.92 ″Hg).
, a.SLP > standard í true altitude > indicated
b.SLP < standard í true altitude < indicated
●
Temperature warmer or colder than standard temperature.
a.Temp. > standard í true altitude > indicated
b.Temp. < standard í true altitude < indicated
●
Strong vertical wind gusts
a.Thunderstorms
b.Mountain/lee waves
Estimate the error between true altitude and indicated altitude when the
Kollsman window (altimeter setting) is incorrectly set - ...(ANSWERS)....You're
flying at an indicated altitude of 3,000 feet MSL over a region where there is a
strong high-pressure area at the surface. The altimeter setting is 30.42"Hg but the
Kollsman window of your altimeter is only set at 30.17 "Hg. Estimate your true
altitude.
3250 feet
Calculate the altimeter setting given station pressure, station elevation and a
standard atmosphere chart - ...(ANSWERS)....see question 8 in pressure altimetry
