#1. Variation is:

#2. What is an isogonal?

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

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

#5. 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) ?

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.


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

#7. In the image, what do the numbers 1184 with 394 in parenthesis depict?

#8. What is the difference between a Great Circle and Rhumb Line?

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

#10. Review the chart excerpt. Which altimeter setting should be used when flying under the base of the Yorkshire CTA over Barnsley to ensure vertical separation from the lower airspace boundary?

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

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


#12. 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?

#13. Zero degrees latitude is found

#14. When variation is nil ...

#15. Typically found on 1:250,000 chart, the transverse Mercator projection method has lines of longitude that:

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

#17. The distance of 1nm is equivalent to

Lines of longitude, also called lines of meridian.

They converge at the poles, with their farthest distance from one another at the equator.

Each degree of latitude is 60nm; each minute, of which sixty make up one degree, is therefore 1 nm.

#18. You have calculated your True Track to destination to be 180°. The magnetic variation is 3° West, and your compass has a deviation of 5° East. Ignoring any wind corrections, what would your final heading on your compass need to be to maintain track?

#19. When viewing the information publication for an airfield, you see the abbreviation "PPR." What does this mean?

#20. Allowing for one hour's reserve fuel, how far can an aircraft travel with 50 litres of useable fuel, using 22 litres per hour with a groundspeed of 90kts?

22 l/hr with 50 litres = 2.273 hours maximum endurance.

Leaving one hour reserve, calculate distance travelled in 1.273 hours (1h16m23s) at 90kt.
