Accepted Answer

1 : 1000000.

Answer

1 : 500000

Answer

1 : 250000.

Answer

1 : 2000000.

Question 5

For a short flight from A to B the pilot extracts the following information from an aeronautical chart: True course: 245°. Magnetic variation: 7° W The magnetic course (MC) equals...

Accepted Answer

252°.

Answer

238°.

Answer

245°.

Answer

007°.

Question 6

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 center 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 center 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 center indicates the track error as angular distance in degrees; the scale for full deflection is +-10°.

Answer

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

Question 7

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 the equator with 45° angle.

Answer

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

Answer

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

Question 8

An aircraft is flying with a true airspeed (TAS) of 180 kt and a headwind component of 25 kt for 2 hours and 25 minutes. The distance flown equals...

Accepted Answer

1 : 1500000

Answer

1 : 500000

Answer

1 : 1 000000

Answer

1 : 150000
