Question 1

VFR Navigation Charts (VNC Series) are based on a Lambert Conformal Conic Projection. The following list contains three properties characteristic of this projection and three other properties characteristics of a Mercator projection.

1. Meridians are straight, parallel lines, intersecting the parallel (which are also straight, parallel lines) at right angles
2. Meridians are converging lines, intersecting the parallels (which are concentric arcs of circles) at right angles
3. A straight line represents a great circle
4. A straight line represents a rhumb line
5. Scale errors are small, hence the scale may be considered constant over a single sheet
6. Scale varies with latitude and is only constant at the equator, hence distance must be measured on the latitude scale adjacent to the area.

Which of the following includes the three items which are characteristic of the Lambert Conformal Conic Projection?

A. A-C-FB. B-D-FC. A-D-ED. B-C-E

Question 2What does a map scale expressed in 1:1,000,000 mean?

A. 1 inch = 8 milesB. 1 inch on the map = one millionth of a mileC. 1 mile equals 1,000,000 inchesD. 1 inch on the map = 1,000,000 inches on the ground

Question 3To determine the location and base of low level controlled airspace, you should consult:

A. The VFR Navigation ChartsB. The VFR Terminal Area ChartsC. The Designated Airspace HandbookD. Any of the above

Question 4Chrome yellow and black strips painted on pylons or on the roof of a building identifies:

A. An area where explosives are in usedB. An open pit mineC. An artillery rangeD. A fur farm

Question 5Magnetic variation is defined as:

A. An error in the compass caused by magnetic fields associated with metal in the airframe and engineB. The difference between the magnetic track and the magnetic heading of the aircraftC. The angle between true north and magnetic north at any given point on the EarthD. The difference between true track and magnetic track

Question 6Complete familiarity with the compass rose is essential to navigation. Which statement is true?

A. The reciprocal of 267° is 117°B. The direction NE is 090°C. Turning right 90° from a heading of 145° results in 235°D. The reciprocal of 115° is 225°
