estimated time of arrival at an en-route point or fix

estimated time of arrival at destination

8) The ICAO definition of ETA is the: Report

actual time of arrival at a point or fix

estimated time of arrival at an en-route point or fix

estimated time of arrival at destination

9) The ICAO definition of ETA is the: Report

actual time of arrival at a point or fix

estimated time of arrival at an en-route point or fix

estimated time of arrival at destination

10) At the magnetic equator, when accelerating after take off on heading West, a direct reading compass : Report

underreads the heading

indicates a turn to the south

indicates the correct heading

11) An island appears 30° to the left of the centre line on an airborne weather radar display. What is the true bearing of the aircraft from the island if at the time of observation the aircraft was on a magnetic heading of 276° with the magnetic variation 12°W? Report

234°

038°

054�

12) The lines on the earth's surface that join points of equal magnetic variation are called: Report

isogrives

isoclines

isogonals

13) An aircraft departing A(N40º 00´ E080º 00´) flies a constant true track of 270º at a ground speed of 120 kt. What are the coordinates of the position reached in 6 HR? Report

N40º 00´ E068º 10´

N40º 00´ E064º 20´

N40� 00� E070� 30�

14) The main reason that day and night, throughout the year, have different duration, is due to the: Report

inclination of the ecliptic to the equator

earth's rotation

relative speed of the sun along the ecliptic

15) The parallels on a Lambert Conformal Conic chart are represented by: Report

arcs of concentric circles

parabolic lines

hyperbolic lines

16) Which of the following is an occasion for carrying out a compass swing on a Direct Reading Compass? Report

Before an aircraft goes on any flight that involves a large change of magnetic latitude

After an aircraft has passed through a severe electrical storm, or has been struck by lightning

Whenever an aircraft carries a large freight load regardless of its content

17) Which one of the following is an advantage of a remote reading compass as compared with a standby compass? Report

It eliminates the effect of turning and acceleration errors by pendulously suspending the detector unit

It is more reliable because it is operated electrically and power is always available from sources within the aircraft

It senses the magnetic meridian instead of seeking it, increasing compass sensitivity

18) Complete the following statement regarding magnetic variation. The charted values of magnetic variation on earth normally change annually due to: Report

magnetic pole movement causing numerical values at all locations to increase or decrease

magnetic pole movement causing numerical values at all locations to increase.

a reducing field strength causing numerical values at all locations to decrease.

19) The Earth can be considered as being a magnet with the: Report

red pole near the north pole of the earth and the direction of the magnetic force pointing straight down to the earth's surface

blue pole near the north pole of the earth and the direction of the magnetic force pointing straight up from the earth's surface

blue pole near the north pole of the earth and the direction of the magnetic force pointing straight down to the earth's surface

20) Given: Chart scale is 1 : 1 850 000. The chart distance between two points is 4 centimetres. Earth distance is approximately : Report

40 NM

74 NM

100 NM
