PSTAR Navigation and Charts 1 — Questions and Answers
Question 1: What type of chart is most commonly used for VFR cross-country navigation in the United States?
- IFR En Route Low Altitude chart
- Sectional Aeronautical Chart (Correct answer)
- Terminal Area Chart
- World Aeronautical Chart
Correct answer: Sectional Aeronautical Chart
Sectional Aeronautical Charts at a scale of 1:500,000 are the standard chart for VFR navigation, showing terrain, airspace, and navigation aids.
Question 2: What is the difference between true north and magnetic north called?
- Deviation
- Variation (Correct answer)
- Declination
- Inclination
Correct answer: Variation
Variation (also called magnetic declination) is the angular difference between true north and magnetic north at a given location.
Question 3: What is the scale of a standard sectional aeronautical chart?
- 1:250,000
- 1:500,000 (Correct answer)
- 1:1,000,000
- 1:2,000,000
Correct answer: 1:500,000
Sectional Aeronautical Charts have a scale of 1:500,000, meaning one inch on the chart equals approximately 6.86 nautical miles.
Question 4: What color is used on sectional charts to indicate Class B airspace?
- Red
- Blue
- Magenta
- Blue with solid lines (Correct answer)
Correct answer: Blue with solid lines
Class B airspace is depicted on sectional charts with solid blue lines forming the upside-down wedding cake shape.
Question 5: On a sectional chart, what does a number in a box with a 'T' symbol indicate?
- Terrain elevation
- Tower height above MSL (Correct answer)
- True airspeed at that point
- Temporary restricted area
Correct answer: Tower height above MSL
A tower symbol on a sectional chart with a number above the T-icon shows the tower's height above mean sea level (MSL) with AGL height in parentheses.
Question 6: What is the maximum elevation figure (MEF) shown in each quadrangle of a sectional chart?
- The average terrain elevation
- The highest known obstacle within that grid quadrant (Correct answer)
- The minimum safe IFR altitude
- The airport elevation
Correct answer: The highest known obstacle within that grid quadrant
The Maximum Elevation Figure (MEF) shown in bold blue numbers is the highest obstacle or terrain in that lat/long quadrangle.
