RPC Aeronautical Charts & Navigation 1 — Questions and Answers
Question 1: On a sectional aeronautical chart, airports with an operating control tower are depicted in what color?
- Magenta
- Blue (Correct answer)
- Green
- Red
Correct answer: Blue
Airports with operating control towers are shown in blue on sectional charts, while uncontrolled airports are depicted in magenta.
Question 2: What does a dashed magenta circle on a sectional chart typically indicate?
- Class D airspace boundary
- Class C airspace outer ring
- Class E airspace with a surface area designation (Correct answer)
- Prohibited area boundary
Correct answer: Class E airspace with a surface area designation
A dashed magenta circle indicates Class E airspace that begins at the surface, often surrounding airports that have instrument approaches but no control tower.
Question 3: On a sectional chart, what does blue shading (vignette) around an airport indicate?
- Class B airspace
- Class E airspace beginning at 1,200 feet AGL (Correct answer)
- Military operations area
- Instrument approaches are available
Correct answer: Class E airspace beginning at 1,200 feet AGL
Blue shading on a sectional chart indicates Class E airspace that transitions from Class G and begins at 1,200 feet AGL.
Question 4: Which aeronautical chart provides the most detailed depiction of airspace around major airports?
- Sectional Chart (1:500,000)
- VFR Terminal Area Chart (1:250,000) (Correct answer)
- World Aeronautical Chart (1:1,000,000)
- IFR Enroute Low Altitude Chart
Correct answer: VFR Terminal Area Chart (1:250,000)
VFR Terminal Area Charts use a larger scale of 1:250,000, providing more detail around Class B airspace and major airports than standard sectional charts.
Question 5: On a sectional chart, what does a solid blue line represent?
- Class C airspace boundary
- Class B airspace boundary (Correct answer)
- Victor airway centerline
- Military training route
Correct answer: Class B airspace boundary
Solid blue lines depict the lateral boundaries of Class B airspace on sectional charts.
Question 6: What does the Maximum Elevation Figure (MEF) displayed in quadrangles on a sectional chart represent?
- The highest terrain elevation only, excluding man-made structures
- The highest known elevation including terrain and obstacles, rounded up to provide clearance (Correct answer)
- The minimum altitude required by ATC for IFR aircraft
- The highest altitude at which VFR flight is permitted
Correct answer: The highest known elevation including terrain and obstacles, rounded up to provide clearance
The MEF represents the highest known feature (terrain or obstacle) within a quadrangle, rounded up to the next 100-foot increment with added buffer, indicating the altitude needed for clearance.
Question 7: A circle with the letter "R" followed by a number on a sectional chart (e.g., R-2508) indicates what type of special use airspace?
- Restricted area (Correct answer)
- Radio navigation facility
- Regulated transition zone
- Required reporting point
Correct answer: Restricted area
"R" followed by a number designates a Restricted Area where flight is subject to restrictions due to hazardous activities such as artillery fire or missile testing.
