Question 1

Comparing the equatorial radius and the polar radius of the Earth, which of the following statements is correct regarding the Earth's geodetic shape?

The Earth is an oblate spheroid; the polar radius is approximately 21.5 NM (0.3%) shorter than the equatorial radius. The Earth is a prolate spheroid; the polar radius is approximately 21.5 NM (0.3%) longer than the equatorial radius. The Earth is a perfect sphere; the polar and equatorial radii are exactly equal to 3,440 NM. The Earth is an oblate spheroid; the polar radius is approximately 80 NM (1.2%) shorter than the equatorial radius.

Correct Answer:

The Earth is an oblate spheroid; the polar radius is approximately 21.5 NM (0.3%) shorter than the equatorial radius.

Question 2

An aircraft departs from position A (60°N, 010°E) and flies due East along the parallel of latitude to position B (60°N, 020°E). What is the distance flown along this parallel?

600 NM 300 NM 520 NM 150 NM

Correct Answer:

300 NM

Question 3

An aircraft flies a distance of 424 NM due West along the parallel of latitude 45°S. What is the change of longitude during this flight?

10° 00' 6° 00' 7° 04' 14° 08'

Correct Answer:

10° 00'

Question 4

Which of the following statements correctly describes the properties of a great circle and a rhumb line?

A great circle has a constantly changing true track (except when along the Equator or a meridian), while a rhumb line maintains a constant true track. A rhumb line represents the shortest distance between any two points on the Earth's surface. A great circle is a straight line on a Mercator projection chart, whereas a rhumb line is curved. A rhumb line always spirals toward the equator, eventually forming a circle around it.

Correct Answer:

A great circle has a constantly changing true track (except when along the Equator or a meridian), while a rhumb line maintains a constant true track.

Question 5

What is the apparent drift rate of a directional gyroscope due to Earth's rotation at a latitude of 45°N?

10.6° per hour clockwise 10.6° per hour counter-clockwise 15.0° per hour clockwise 7.5° per hour clockwise

Correct Answer:

10.6° per hour clockwise
