Answer 2

Phase comparison

Question 3

What is a VOR radial

Answer 3

Magnetic bearing from the station

Question 4

Where are lambert projections best suited

Answer 4

Mid latitude regions such as Europe USA and Australia

Question 5

What is the angle between the earths magnetic field and the horizontal

Answer 5

Dip or Z

Question 6

When taking off from runway 22 you are given a wind reading of 240/20 what is the approximate crosswind component?

Answer 6

7kts

Question 7

An aircraft travels north along the same meridian from latitude 20° 15’ south to 10° 00’ south. What is the distance flown in kilometres?

Answer 7

1139km

An aircraft travels north along the same meridian from latitude 30° 15’ south to 14° 00’ south. What is the distance flown in kilometres?

20° 15’ – 10° = 10° 15’

(1 degree of latitude = 60nm)

10 x 60 = 600nm

960 + 15’ (15nm) = 615nm

Answer is in km (1nm = 1.852km)

so 615nm x 1.852 = 1139km

Question 8

When requesting a magnetic bearing to a VDF station, the correct Q code phrase to use is:

Answer 8

QDM

BEARING TO - No R in it

QTE	= True bearing from the station
QDR = Magnetic bearing from the station
QDM = Magnetic bearing to the station
QTF	= Position of a station taken by bearings from D/F stations
QUJ	= True bearing to the station

Question 9

When requesting a magnetic bearing from a VDF station, the correct Q code phrase to use is:

Answer 9

QDR

BEARING F(R)OM - It has an R in it

QTE	= True bearing from the station
QDR = Magnetic bearing from the station
QDM = Magnetic bearing to the station
QTF	= Position of a station taken by bearings from D/F stations
QUJ	= True bearing to the station

Question 10

An aircraft travels north along the same meridian from latitude 40° 15’ north to 24° 15’ north. What is the distance flown in nautical miles?

Answer 10

960nm

An aircraft travels north along the same meridian from latitude 40° 15’ south to 24° 15’ south. What is the distance flown in kilometres?

40° 15’ – 24° 15’ = 16°

(1 degree of latitude = 60nm)

16 x 60 = 960nm

Question 11

If the scale of a chart is given as 1:500,000, how many km does 5cm represent?

Answer 11

25km

5 / 100,000 = 0.00005
0.00005 * 500,000 = 25

or just * by 5

A common chart scale for general aviation flying is 1:500 000.

This scale means that 1cm = 500 000cm on the earth’s surface.

Question 12

The Lambert conformal conic chart was devised to be best suited for coverage of which areas of the Earth?

Answer 12

mid-latitudes

Question 13

A line of latitude

Answer 13

varies from 0° at the equator to 90° North and South at the poles

The longitude of a point has a shorter angular distance measured east/west from the Greenwich meridian.

Question 14

An aircraft tracking 240° with 10° right drift; variation from the chart is 5°E and the compass correction card indicates 3°E. What is the required compass heading?

Answer 14

222°

240°- 10° right drift = 230°
230° - 5°E = 225°
225° - 3°E = 222°

Question 15

When requesting a true bearing to a VDF station, the correct Q code phrase to use is:

Answer 15

QUJ

QTE	= True bearing from the station
QDR = Magnetic bearing from the station
QDM = Magnetic bearing to the station
QTF	= Position of a station taken by bearings from D/F stations
QUJ	= True bearing to the station

Question 16

The longitude of a point is best described as the:

Answer 16

shorter angular distance measured east/west from the Greenwich meridian

The longitude of a point has a shorter angular distance measured east/west from the Greenwich meridian.

Question 17

With the sun coming up, sunrise is said to occur when the:

Answer 17

upper limb of the sun (the first bit to become visible) is on the observer’s horizon

Question 18

A magnetic compass is designed to use the horizontal component, of the earth’s magnetic field. The compass will be most accurate:

Answer 18

at low latitudes

Dip is the angle between the horizontal and total components of the earth’s magnetic field.

As latitude increases the horizontal component of the earth’s magnetic field decreases and the dip increases.

At the magnetic equator dip is 0° and at the magnetic poles dip is at its maximum of 90°.

The compass is most accurate at low latitudes where dip is lowest.

Question 19

With the sun’s altitude decreasing, sunset occurs when the:

Answer 19

upper limb of the sun is on the observer’s horizon
