Question 7

When using a GPS for tracking to the next waypoint, a deviation indication is shown by a vertical bar and dots to the left and to the right of the bar. What statement describes the correct interpretation of the display?

Accepted Answer

The deviation of the bar from the centre indicates the track error as absolute distance in NM; the scale for full deflection depends on the operating mode of the GPS

Answer

The deviation of the bar from the centre indicates the track error as angular distance in degrees; the scale for full deflection depends on the operating mode of the GPS

Answer

The deviation of the bar from the centre indicates the track error as angular distance in degrees; the scale for full deflection is +-10°

Answer

The deviation of the bar from the centre indicates the track error as absolute distance in NM; the scale for full deflection is +-10 NM

Accepted Answer

12° to the right

Answer

18° to the right

Answer

9° to the right

Answer

6° to the right

Question 10

Which statement about a rhumb line is correct?

Accepted Answer

A rhumb line cuts each meridian at the same angle

Answer

A rhumb line is a great circle intersecting the equator with 45° angle

Answer

The centre of a complete cycle of a rhumb line is always the Earth's centre

Answer

The shortest track between two points along the Earth's surface follows a rhumb line
