Question 1

Which of the following ratios correctly defines the flattening (compression) of the Earth spheroid?

(a - b) / a, where a is the semi-major axis and b is the semi-minor axis (a - b) / b, where a is the semi-major axis and b is the semi-minor axis (a + b) / a, where a is the semi-major axis and b is the semi-minor axis b / a, where a is the semi-major axis and b is the semi-minor axis

Correct Answer:

(a - b) / a, where a is the semi-major axis and b is the semi-minor axis

Question 2

What is the primary difference between geodetic latitude and geocentric latitude?

Geodetic latitude is measured relative to the local horizon, while geocentric latitude is measured relative to the Earth's true polar axis. Geodetic latitude is the angle between the equatorial plane and the normal to the spheroid at that point, while geocentric latitude is the angle between the equatorial plane and a line connecting the point to the Earth's center. Geodetic latitude is measured in statute miles from the equator, while geocentric latitude is measured in nautical miles from the prime meridian. Geodetic latitude accounts for the Earth's rotation speed, while geocentric latitude is a static coordinate based on Keplerian orbits.

Correct Answer:

Geodetic latitude is the angle between the equatorial plane and the normal to the spheroid at that point, while geocentric latitude is the angle between the equatorial plane and a line connecting the point to the Earth's center.

Question 3

Calculate the departure distance between two positions on parallel of latitude 60°N: Position A is at 010°W and Position B is at 020°W.

600 NM 300 NM 520 NM 150 NM

Correct Answer:

300 NM

Question 4

What is the distance along a Great Circle path between Position X (00°00'N/S, 010°00'E) and Position Y (00°00'N/S, 025°00'E)?

900 NM 1500 NM 450 NM 779 NM

Correct Answer:

900 NM

Question 5

Calculate the earth convergence angle between two meridians of longitude separated by 20° at a mean latitude of 45°N.

20.0° 14.1° 10.0° 7.1°

Correct Answer:

14.1°
