Question 1

Which ellipsoidal parameters best define the reference shape of the Earth used in modern satellite navigation (WGS-84) and aeronautical charting?

An oblate spheroid with a equatorial radius (~6378 km) slightly larger than its polar radius (~6357 km), flattened at the poles by approximately 1/298.25 A prolate spheroid with a polar radius larger than its equatorial radius by approximately 1/298.25 A perfect sphere with a uniform radius of 6371 km across all parallels and meridians A triaxial ellipsoid where all three principal axes differ in length by over 5%

Correct Answer:

An oblate spheroid with a equatorial radius (~6378 km) slightly larger than its polar radius (~6357 km), flattened at the poles by approximately 1/298.25

Question 2

By international standard definition, one international Nautical Mile (NM) is equal to exactly:

1,852 metres (6,076.1 feet) 1,609 metres (5,280.0 feet) 2,000 metres (6,561.7 feet) 1,760 metres (5,774.3 feet)

Correct Answer:

1,852 metres (6,076.1 feet)

Question 3

What is the standard formula for Departure (distance in nautical miles along a parallel of latitude between two meridians)?

Departure (NM) = Change of Longitude (minutes of \arc) × cos(Latitude) Departure (NM) = Change of Longitude (minutes of \arc) × sin(Latitude) Departure (NM) = Change of Latitude (minutes of \arc) × cos(Longitude) Departure (NM) = Change of Longitude (degrees) × 60 × tan(Latitude)

Correct Answer:

Departure (NM) = Change of Longitude (minutes of \arc) × cos(Latitude)

Question 4

An aircraft positioned at 26°00'S 028°00'E flies due West along the parallel of 26°S to 025°00'E. Calculate the departure distance flown.

161.8 NM 180.0 NM 141.5 NM 198.2 NM

Correct Answer:

161.8 NM

Question 5

Which statement correctly describes the geometric differences between a Great Circle track and a Rhumb Line track on the Earth's surface?

A Great Circle is the shortest distance between two points whose plane passes through the centre of the Earth, whereas a Rhumb Line crosses all meridians at a constant angle A Rhumb Line is the shortest distance between two points, while a Great Circle maintains a constant true heading All parallels of latitude \are Great Circles, whereas meridians of longitude \are Rhumb Lines A Great Circle track maintains a constant track direction relative to Magnetic North, while a Rhumb Line changes track continuously

Correct Answer:

A Great Circle is the shortest distance between two points whose plane passes through the centre of the Earth, whereas a Rhumb Line crosses all meridians at a constant angle
