WITH UPDATED QUESTIONS AND ANSWERS
Section 1: Basics of Navigation (Q1–Q30)
1. What is the primary reference line for measuring latitude?
A. The Prime Meridian
B. The Equator
C. The International Date Line
D. The Ecliptic
B. The Equator
Latitude is the angular distance north or south of the Equator, measured
along a meridian from 0° at the Equator to 90° at the poles. The Equator is the
fundamental reference plane for latitude.
2. The angular distance measured east or west of the Prime Meridian is called:
A. Latitude
B. Longitude
C. Variation
D. Deviation
B. Longitude
Longitude is measured east or west of the Prime Meridian (0°) at
Greenwich, from 0° to 180°.
3. How many minutes of arc are in one degree?
A. 30
B. 60
C. 90
D. 100
, B. 60
One degree (°) equals 60 minutes of arc (′). One minute of arc equals 60
seconds of arc (″).
4. One minute of latitude is approximately equal to:
A. 1 statute mile
B. 1 nautical mile
C. 1 kilometre
D. 1.15 nautical miles
B. 1 nautical mile
One minute of latitude is approximately equal to one nautical mile (1 NM
= 6,076.1 feet = 1,852 metres). This is the basis for the nautical mile.
5. The shape of the Earth is best described as:
A. A perfect sphere
B. An oblate spheroid
C. A prolate spheroid
D. A geoid
B. An oblate spheroid
The Earth is an oblate spheroid — flattened at the poles and bulging at the
Equator. The polar diameter is approximately 6,864 NM while the equatorial
diameter is approximately 6,887 NM.
6. A great circle is defined as:
A. Any circle on the surface of the Earth
B. A circle whose plane passes through the centre of the Earth
C. A line of constant latitude
D. A rhumb line
, B. A circle whose plane passes through the centre of the Earth
A great circle is the largest possible circle that can be drawn on a sphere —
its plane passes through the centre. The shortest distance between two points on
a sphere lies along the arc of a great circle.
7. Which of the following is a great circle?
A. The Equator
B. A line of latitude at 45°N
C. A line of latitude at 60°S
D. A small circle
A. The Equator
The Equator is a great circle because its plane passes through the Earth's
centre. All meridians are also great circles (when paired with their opposite
meridian). Lines of latitude other than the Equator are small circles.
8. A rhumb line is:
A. A line that crosses all meridians at the same angle
B. The shortest distance between two points
C. A great circle
D. A line of constant longitude
A. A line that crosses all meridians at the same angle
A rhumb line (loxodrome) crosses every meridian at the same angle and
appears as a straight line on a Mercator chart. It is not the shortest distance but is
easier to fly constant heading.
9. The shortest distance between two points on the Earth's surface is along:
A. A rhumb line
B. A great circle
, C. A parallel of latitude
D. A meridian
B. A great circle
The great circle track is the shortest distance between two points. On a
Mercator chart, it appears as a curved line convex to the nearest pole.
10. Which of the following is NOT a unit of distance used in aviation?
A. Nautical mile
B. Statute mile
C. Kilometre
D. Knot
D. Knot
A knot is a unit of speed (nautical miles per hour), not distance. Nautical
miles, statute miles, and kilometres are units of distance.
11. 1 nautical mile is equal to:
A. 1,852 metres
B. 1,609 metres
C. 1,000 metres
D. 2,000 metres
A. 1,852 metres
1 NM = 1,852 metres = 6,076.1 feet. 1 statute mile = 1,609 metres.
12. The term "true north" refers to:
A. The direction indicated by a magnetic compass
B. The direction of the geographic North Pole
C. The direction of the magnetic North Pole
D. The direction of grid north
