Aviation Navigation & Charts 1 — Questions and Answers
Question 1: On a VFR sectional chart, what color is used to depict Class B airspace?
- Blue
- Magenta
- Red
- 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 its multiple tiers.
Question 2: What does a VORTAC provide that a VOR alone does not?
- Glide slope
- TACAN distance (DME) information (Correct answer)
- ILS localizer
- Weather broadcast
Correct answer: TACAN distance (DME) information
A VORTAC combines a VOR with a TACAN, providing both azimuth and distance (DME) information to military and civilian aircraft.
Question 3: When using a sectional chart, the magnetic variation is shown by which line?
- Contour line
- Isogonic line (Correct answer)
- Isobar
- Latitude line
Correct answer: Isogonic line
Isogonic lines on sectional charts connect points of equal magnetic variation and are shown as dashed lines with the variation value labeled.
Question 4: What is the maximum scale for a VFR Terminal Area Chart (TAC)?
- 1:250,000 (Correct answer)
- 1:500,000
- 1:1,000,000
- 1:125,000
Correct answer: 1:250,000
Terminal Area Charts are published at a scale of 1:250,000, twice the scale of standard sectional charts.
Question 5: On a sectional chart, a symbol showing a circle with an 'R' inside indicates which type of airspace?
- Restricted area (Correct answer)
- Runway protection zone
- Radio mandatory zone
- Radar coverage
Correct answer: Restricted area
A circle with 'R' followed by a number on a sectional chart identifies a restricted area (e.g., R-2508).
Question 6: What is the purpose of the latitude and longitude lines on an aeronautical chart?
- They show magnetic headings
- They provide a coordinate grid for position fixing (Correct answer)
- They indicate wind direction
- They mark airways
Correct answer: They provide a coordinate grid for position fixing
Latitude and longitude lines form a geographic coordinate grid used to identify and report aircraft positions precisely.
