1184 feet is the mast's top elevation above ground, and 394 feet is a safety altitude for clearance.

Mast number 1184 (see chart legend for details) has its top at 394 feet above mean sea level.

1184 feet is the mast's top elevation above ground, for mast number 394 (see chart legend for details)

1184 feet is the mast's top elevation above mean sea level, and 394 feet is its height above ground.

#3. What is an isogonal?

A line joining places of nil deviation

A line joining places of equal deviation

A line joining places of nil variation

A line joining places of equal variation

#4. An aircraft is flying with a true airspeed (TAS) of 180kt and a headwind component of 25kt for 2 hours and 25 minutes. What is the total distance flown?

375nm

435nm

202nm

With a 25 kt headwind component, the groundspeed of the aircraft would be 155kt.

155 kt for 2:25 = 375nm

#5. When variation is nil ...

compass and magnetic direction are the same

the compass must be broken

there is no angle of dip

true and magnetic direction are the same

#6. The shortest track between two points on the earth is called

a Great Circle

a direct meridian

a Rhumb Line

#7. If a pilot changes an altimeter setting from 986hPa to 1013hPa, the altitude indication will:

remain the same

increase

decrease

#8. On a chart, 12cm represents 60km, what is the scale of the chart?

1:500,000

1:250,000

1:1,000,000

On a 1:500,000 (or “half-mill”) chart, each centimetre represents an actual distance of 50,000cm – or 500m, 0.5km.

#9. An aircraft is heading 201° with 12° left drift; variation from the chart is 6°W and the compass correction card indicates 6°E deviation. What is the aircraft's true track?

213°

189°

203°

#10. A rhumb line

is always curved on any chart

is always a straight line on any chart

cut meridians at the same angle

#11. The Lambert Conformal Conic Projection method used on 1:500,000 scale charts:

has lines of longitude converge toward poles

has lines of longitude parallel to one another

has lines of latitude converge at the poles

has lines of latitude diverge at the poles

#12. Zero degrees latitude is found

at the equator

in the Southern Hemisphere

Over Greenwich, London, UK

in the Northern Hemisphere

#13. An aircraft is heading 270° with 7° left drift; variation from the chart is 2°W and the compass correction card indicates 4°E deviation. What is the aircraft's true track?

265°

269°

253°

#14. True heading is 270°. Magnetic variation is 10° East. What is magnetic heading?

280°

Cannot be calculated, insufficient information

260°

270°

#15. You plan a flight over Barnsley. By Referencing the 1:500,000 chart, you note that the Yorkshire CTA (A) is above Barnsley. With a QNH of 1006 Hectopascals, the base of the Yorkshire CTA over Barnsley will be at approximately which altitude above mean sea level (AMSL) ?

4,939ft

5,500ft

5,290ft

5,710ft

The Yorkshire CTA is at FL55 (Flight level 55 and above), 5500 feet using standard pressure settings (QNE.)

This is assuming an altimeter subscale setting of 1013 hectopascals.

With the given QNH of 1006 hPa, there is a difference of 7 hPa under the QNE standard; assuming 30 feet per hPa, 30 x 7 = 210, so the base of the CTA would be 5500-210 = 5290 feet altitude.

The question here has been kind enough to remind you that altitude is expressed as above mean sea level.

Height is above ground, and flight levels are assuming a fixed setting of 1013 hPa, irrespective of current meteorological conditions.

#16. In reference to the earth's magnetic field, Where is dip the greatest?

Dip is equal at all locations around the earth

The magnetic equator

The magnetic poles

#17. Refer to the image with the MEF (Maximum Elevation Figure) circled. Which of the following statements is correct?

One should fly above 2600 feet altitude in order to avoid hitting any obstacles.

One should fly at a flight level 0026 in order to avoid hitting any obstacles.

One should fly at least 2600 feet altitude in order to avoid hitting any obstacles.

One is not permitted to fly about 2600 feet altitude in that quadrant.

#18. Variation is:

The angular difference between true and magnetic north

The angular difference between isogonals and the agonic line

The angular difference between true and compass north

The angular difference between magnetic and compass north

#19. An aerodrome is marked on a chart with the letters FIG and a Morse code pattern. What does this mean?

There is an aerodrome light beacon which flashes green

When the light flashes green, the aerodrome is open to all traffic

The aerodrome uses green light signals at night

#20. The circled large number 2 with smaller number 6 in the image depicted is a Maximum Elevation Figure (MEF). What defines this?

The highest elevation above the immediate surrounding ground within a quadrant, including terrain and other vertical obstacles.

The highest elevation depicted as a flight level within a quadrant, including terrain and other vertical obstacles.

The highest altitude above mean sea level one can fly at within Visual Flying Rules.

The highest elevation above mean sea level within a quadrant, including terrain and other vertical obstacles.

How an MEF is worked out:

Elevation of obstacle top, above mean sea level: 2424

Possible vertical error: 100

added together = 2524

Raise to the following 100′ level: 2600

MEF: 2^6
